Full textAbstract:
Renovating old neighborhoods for the benefit of people has become increasingly important in urban renewal. Nevertheless, old neighborhood renovations are currently considered a group decision-making issue under public participation, involving diverse decision-making subjects. Conflicts within a group are a common problem during group decision-making. In this paper, conflict is examined in the decision-making process for renovating old neighborhoods and novel ideas are provided for quantifying conflict. Public participation in old neighborhood renovations is assessed using conflict degree calculations in group decision-making. Based on the preferences of decision-making experts, a MIP DEA–DA (Mixed Integer Programming Data Envelopment Analysis–Discriminant Analysis) based partial binary tree cyclic clustering model is constructed for clustering experts, and an aggregated group conflict indicator and an aggregated conflict vector are computed, allowing for the quantification of conflict during the renovation process of the old neighborhood based on actual situations. Results indicate that there is primarily a conflict between the benefits of decision-making subject interests and the professionalism of decision-making renovations. This paper contributes to improving public participation, promoting the application of group decision-making theory in old neighborhood renovation, reducing conflict between decision-makers, and speeding up urban renewal.

ABSTRACT With the progress of urbanization, most people live in cities and adjacent urban areas. Meanwhile, the transformation and development of cities and their industries leaves behind a large volume of old building blocks and requires renovating some urban spaces. Notably, urban renewal plays an important role in the sustainable development of cities. As a typical task of urban renewal, the renovation of industrial buildings involves the protection of the industrial heritage and the adaptive reuse of the existing building spaces. Yet, the complex nature of district-level industrial building renovation work spells challenges to effective urban renovation and sustainable city renewal. Although a few studies were devoted to the renovation of industrial buildings, very limited research focused on the renovation of existing industrial urban areas. In particular, the cooperation of different work disciplines to orchestrate sustainable district-level industrial building renovation and strategies to facilitate effective administration of such a way of urban renewal remain to be clarified. To close such a gap, this research employs an approach of multi-case study to conceptualize sustainable district-level industrial building renovation. Four case projects from the Big Bay Area cities, including Dongguan, Foshan, Guangzhou, Shenzhen, are investigated and analyzed due to specific local policies of renovation and their rapid urbanization. Based on the knowledge disciplines of urban planning, industrial heritage reservation, and building renovation, a taxonomy framework is introduced, and the relevant sustainable development strategies are identified. The framework demystifies sustainable district-level industrial building renovation regarding the key aspects of sustainable management to achieve sustainable urban renewal and their hierarchical relations and enhances the knowledge body of industrial building renovation by broadening the scope to the urban scale. Furthermore, the proposed strategies can provide practical implications to sustainable urban renewal with industrial building renovation.

Full textAbstract:
There is an urgent need for energy renovation of the existing building stock, in order to reach the climate goals, set in Paris in 2016. To reach climate targets, it is important to considerably lower energy demand as well as switch to fossil-free heating systems. Unfortunately, renovation rates across the EU remain at a low level of 1% per year. Deep renovation, which lowers energy use with 60% or more, accounts only for 0,2% of renovations. The heating transition thus progresses much more slowly than the electricity transition. We draw on the framework of technological innovation systems, which allows comparison of different transitions. In the literature, it is argued that the configurational nature of the renovation system is one of the main reasons for the slow heating transition. The renovation system is context-bound and consists of many actors both on the demand-side and the supply-side, which leads to a fragmented market. For increasing the speed of the heating transition, it is deemed important to counter this fragmentation. We carried out a review of reports and publications of EU-funded projects on energy renovation. In many projects fragmentation in the building sector was identified as one of the main obstacles. We analyzed the deliverables of these energy renovation projects to find tried and tested solutions. One of these is the so-called one-stop-shop, which promises to improve the organization of the supply side, while also providing an appropriate and affordable solution to the customer. In the discussion we argue that the energy renovation system could be improved by increasing collaboration on the supply side and at the same time simplifying the renovation process for customers. A promising tool to make this happen is the one-stop-shop.

Building energy renovations contribute significantly to energy sustainability and environmental protection. These advantages have increased the importance of renovating existing residential buildings in many countries. In China, the government has supported the energy-saving renovation of existing urban residential buildings since 2007. However, quality failures, which do not meet the technical requirements, occur during construction processes in building energy renovation projects. Although quality failures are regarded as a crucial problem in building energy renovation projects, the identification of quality failures and their sources, likelihood, impacts, and causes remain mostly unknown. This paper investigates the nature of quality failures in building energy renovation projects. A total of 25 quality failures were first identified through five cases, and interviews with six experienced construction professionals in China. A questionnaire survey was further conducted to evaluate the frequency of quality failures. The results show the nature of quality failures that arise during construction and their sources, occurrence frequency, causes, and impacts. The research reveals that quality failures are caused by defaults by workers; inadequate checking procedures; incomplete construction site surveys; inaccurate design work; fraud of construction companies; and inefficient cooperation between different departments. Above all, the behaviors of the main actors are responsible for poor construction quality. Additionally, emphasis on quality control during the renovation preparation stage is critical to ensure that quality failures are reduced in numbers and severity.

Full textAbstract:
Renovating buildings with cultural heritage significance is an important step toward achieving sustainability in our cities. The benefits are not only energy-related but also encompass social aspects that make these renovations a high apriority. The present work investigates the renovation process of a cultural heritage building in the Municipality of Trento in Italy, specifically focusing on achieving energy savings and renewable energy integration by implementing various renovation actions. These renovation actions include improvements to the building envelope, such as roof insulation and window replacements. Additionally, the renovation actions for active systems involve the installation of a ground-source heat pump for heating/cooling coupled with a borehole thermal energy storage system, which is an innovative technology for the renovation of cultural heritage buildings. The electrical systems of the building are upgraded through the addition of standard rooftop photovoltaics, innovative building-integrated photovoltaics (shingles), and the installation of an LED lighting system. The baseline and the renovation scenarios are studied using the dynamic simulation tool INTEMA.building, written in the programming language Modelica. This tool simulates both the building envelope and the energy systems with a high level of detail, using advanced control systems and adjustable time steps. According to the simulation analysis, the primary energy demand is reduced by 30.49%, the final energy demand by 36.74%, and the net electricity demand by 8.72%. Results from this study can be useful to interested stakeholders (e.g., building owners, architects, construction companies, public agents, and urban planners) dealing with the renovation of cultural heritage and protected buildings. Also, the results can be exploited for estimating energy savings by applying advanced renovation strategies for cultural heritage buildings.

Full textAbstract:
The scaling up of zero energy (ZE) renovations contributes to the energy transition. Yet ZE renovations can be complex and error-prone in both process and outcome. This article draws on theory from sociotechnical design, participatory design, and inclusive design to analyse four recent case studies of ZE renovation/building in the Netherlands. The cases are studied using a mix of retrospective interviews and workshops, as well as ethnographic research. Three of the cases studied are ZE renovations of which two are recently completed and one is in progress, while the fourth case is a recently completed ZE new build. Three of the cases are social housing and one is mixed ownership. The research enquired into the situation of the project managers conducting the processes and also drew on resident experiences. The ZE renovation/builds are analysed as sociotechnical product-service systems (PSSs). The article evaluates how the use values, product values, and result values of these PSSs emerged from the processes. This perspective reveals issues with the usability of the PSSs, as well as with cost structures, technical tweaks, and maintenance agreements. Applying a design perspective provides starting points for co-learning strategies that could improve outcomes. Two example strategies that have potential in this regard are described, using demo dwellings and user manual as PSS prototypes in the early design phase. These and similar strategies could support the professionals in the field in creating successful ZE renovation/building processes.

The article discusses the possibility of renovating park areas in order to create public spaces, taking into account all the existing problems of this area, the wishes of residents and the foundations of sustainable development. The main objectives of the study are: to analyze the environmental, natural and anthropogenic factors of mutual influence, as well as the interaction of the relevant systems in areas with urban development, its slow development, and especially during reconstruction and renovation; to substantiate the problem of renovation of urban spaces in the ratio of city-forming zones (industrial, rural and recreational); trace the development of park areas in connection with the development of the city and determine ways to solve the problems of renovation of urban spaces; present a comprehensive architectural concept of linking park and recreation areas and development of the coast of the Odessa Bay. After analyzing the history of the emergence and development of parks in Ukraine, first of all, the historical features of the territory where the hydropark "Luzanovka" is located, the importance of this park area for various factors (environmental, social, urban planning, etc.) is revealed. The introduction of new functions in the territories of historical parks, the competent development of an urban planning structure through the renovation and rehabilitation of the territory will lead to an influx of funds and investors, and will make it possible to reproduce and maintain parks at a new historical stage. The article presents the features of the design and renovation of parks, identifies trends in the further development of the territory, presents social and environmental effects, and provides an example of a project for the renovation of the Luzanovka hydropark.

Full textAbstract:
The European Commission and EU member states have prioritised the renovation of the existing housing stock as a means of achieving their energy-efficiency targets. As buildings account for 40% of Europe’s energy consumption and much of this is used in the residential sector a major breakthrough could be realized here. Despite the fact that energy saving targets have been prioritized in EU and national policy programme’s, progress is slow. The actual rate and extent of renovations are by fare not enough to achieve the targets. Although the necessity of energy savings is acknowledged by institutional investors in housing, housing associations, individual homeowners and occupants, it appears to be difficult to get sufficient support for energy efficiency renovations. The current economic situation is an additional barrier preventing large scale investments in energy renovating the housing stock. This article connects the realisation of energy efficiency goals with the creation of jobs in the EU. The shift from new-build to renovation will have considerable effects on employment in especially the construction industry and the qualifications required by the workforce. Studies show that for every €1 million investment in the existing building stock in the form of energy renovation work, 12 to 17 new jobs could be created. Potentially this could lead to may new jobs. However, there are many uncertainties in these calculations. Are these direct or indirect jobs, what sectors would benefit, are these jobs created within the EU and what would be the net effect on the labour market? Nonetheless these uncertainties, the positive employment effects will prevail. A new and ambitious investment programme in the housing sector could not only improve the energy performance of the sector but create 100.000’s of valuable jobs at a time when these are seriously needed.

Full textAbstract:
We analyze the financial returns to a green building renovation project for a small commercial office building in the urban Midwest. Compared with a comparable conventional renovation, the LEED renovation required additional building costs of approximately $7.41 per square foot. This additional up-front investment, or “green premium,” promises to generate an estimated $1.38 per square foot in annual savings, mostly from reduced energy expenditures. Viewed strictly in financial terms as an investment opportunity, the LEED renovation offered an expected Internal Rate of Return (IRR) of approximately 12%. A sensitivity analysis suggests that this estimate is relatively robust across a range of alternative model assumptions. The findings suggest that LEED renovations could be very attractive to organizations with relatively low capital costs, such as government agencies, but might prove marginal or unattractive to smaller private firms with high costs of capital.

To optimize the organizational and technological model of construction of buildings and structures in a dense urban environment, it is necessary to take into account the factors that have a destabilizing effect on the process of construction and installation works, and arising from the very definition of " constrained urban development", which involves getting near buildings, structures and linearly extended objects in the zone of influence of new construction or reconstruction. This article highlights a number of destabilizing factors that most strongly affect the time and economic costs that must be considered when developing a construction project.

Introduction. The problem of rehabilitation and modernization of panel residential buildings covered many European countries in the nineties. The renovation programme started in Moscow in 2017. Despite the typical panel mass housing construction in European countries and in Russia, there are still many urban planning, architectural and construction differences, and therefore different methods of residential renovation have been adopted. Considerable positive and negative construction experience has been accumulated over the past period which should be taken into account for the extension of the renovation to Russian regions.
Materials and methods. The analysis of socio-economic methods of rehabilitation and modernization of residential buildings in several European countries was carried out, and the experience of residential buildings renovation in Moscow was studied in detail. The organizational and financial conditions for the implementation of residential rehabilitation and renovation programs have been studied and a number of features have been noted.
Results. Based on the studied methods of implementation of rehabilitation, modernization and renovation programs in European cities and in Moscow, a table with positive and negative factors was compiled. Considering these factors, a flowchart for the choice of renovation method in relation to the specific built-up area was developed. The socio-economic vector ofthe renovation programme on the management of the housing and communal services has been proposed.
Conclusions. When choosing a method of renovation of residential buildings, it is necessary to consider the interests of residents and business entities. For megacities where the number and density of the population is high, the Moscow model of renovation may be preferable, taking into account positive and negative experience. For small cities in Russia, where low-rise buildings are of historical and architectural value and a population density is low, the European renovation experience can be applied. When developing renovation programs, it is important to maintain a balance between new construction and the preservation of historically established urban development.

Open policy reform has been implemented more than 40 years, the city construction and development of China turns out new face very fast. China evolved the grid and applied it to the planning, construction and ordering of its great imperial capital cities. Urban villages are a product of China's urban-rural dual system and rapid urbanization. In early China, the renovation of urban villages mainly focused on demolition and reconstruction, neglecting the residents' demand for high-quality housing. With institutional changes and the development of urban governance concepts, urban village renovation has begun to adopt organic renewal and micro renovation methods, and more emphasis has been placed on the quality of urban living. This research mainly explores the impact of policy changes on the transformation of urban villages from the perspectives of institutional change theory and transaction cost theory. This study also compared the policy differences and impacts of urban village renovation between Zhengzhou and Shenzhen. In the process of urban village transformation, it is necessary to consider the impact of institutional environment on urban village transformation policy.

Renovation philosophy and residential construction mode are key problems encountered in the renovation of urban villages in China. Existing research fruits on renovation philosophy, and policies consider fairness and efficiency and cover-sharing research consensus. However, research on residential construction mode in renovation still faces challenges, such as weak relevant policy pertinence, insufficient objective references, and poor universality. In this study, the changes of the architectural spaces of a typical urban village community in Xi'an City from the beginning to the end of the renovation were discussed. The space requirements of different user groups were analyzed and summarized, and then adapted to the different types of building spaces. In addition, the residential construction model applicable to the inclusive renovation philosophy was established. Research results corroborated that the renovation of urban village should refer to its functional orientations in the community. The community-centered renovation residential district should also meet the requirements of different user groups in the community, including residential, living, and entertainment functions. Community-subcentered residential district should meet the space demands of residential and living functions. Community-subordinated residential district meets space demands of internal residents for residential and living. Moreover, residential district space is relieved by combining practical and certain spatial factors. In this research, the building space compositions of different user groups were reviewed and refined in the “bottom-up” pattern. Research conclusions provide design references for the practical renovation of urban villages.

Building energy renovations can effectively improve the environmental performance and energy sustainability of existing buildings. From 2007 onwards, the Chinese government has promoted energy-saving renovations of existing urban residential buildings. Nevertheless, various quality failures happen during the construction period in energy-saving renovation projects of residential buildings. Yet, the causes and their characters remain largely unknown. Through a literature review, this paper investigates the causes of quality failures. Validated through experts’ interviews, a total of 18 causes were identified in building energy renovation projects. These causes were analyzed from two main aspects: the importance of a cause (related to impact and frequency), and the level of effort required to address a cause (related to origin and scale), using both a questionnaire survey and a focus group. The results indicate that the critical causes of quality failures are working under high-cost and high-time pressure, adverse natural conditions, fraud of construction companies, incomplete construction site survey, poor checking procedures of supervisors, poor operational skilled workers, inadequate equipment performance, lack of experienced project managers, and incomplete building information in projects. The causes were classified as external and internal causes of building energy renovation projects. The outcome of this paper should aid policy makers and project coordinators to focus on critical causes of quality failures, and to develop effective actions and policy interventions to achieve successful renovation projects with high-quality performance.

More significant reductions in residential primary energy consumption and in space heating in particular, can contribute to achieving climate change and energy efficiency objectives. Project information from demonstration projects is now becoming available for highly energy-efficient renovation concepts. The goal of this research is to understand how owner-occupants can be persuaded to apply far-reaching energy-saving renovations of single-family houses. To this end, the research examines drivers and barriers of owners to adopt highly energy-efficient renovation concepts. Theory on decision processes in innovation diffusion is used, in order to examine the adoption of integrated concepts to achieve high energy performance. Belgian case studies (different building typologies) were examined. Adoption drivers and barriers perceived by owner-occupants are analysed. This leads to improved understanding of characteristics that can persuade future adopters. Possible measures are discussed to overcome barriers in the introduction phase of innovation diffusion, and are illustrated more in detail with a case study. The research shows that especially expectations of improved comfort provide an opportunity for the market entry of integrated concepts. Owners, architects and contractors could benefit from increased attractiveness, competitiveness, affordability and availability of highly energy-efficient renovations. Holistic approaches (stronger coordination and clustered renovation concepts), higher skill competence (education) and improved communication (actor networks, significant economic incentives) are recommended.

One of the most complex and urgent challenges in the energy transition is the large-scale refurbishment of the existing housing stock in the built environment. In order to comply with the goals of the Paris convention, the aim is to live “energy-neutral,” that is, a dwelling should produce as much sustainable energy as it consumes on a yearly basis. This means that millions of existing houses need to undergo a radical energy retrofit. In the next 30 years, all dwellings should be upgraded to nearly zero-energy buildings, which is a challenge to accomplish for a reasonable price. Across the EU, many projects have developed successful approaches to the improvement of building technologies and processes, as well a better involvement of citizens. It is important to compare and contrast such approaches and disseminate lessons learned. In practice, it is crucial to raise the level of participation of inhabitants in neighborhood renovation activities. Therefore, the central question of this issue is: How can we increase the involvement of tenants and homeowners into this radical energy renovation?

Urban forest ecosystems are increasingly recognized as necessary components of a city's overall sustainability. The number of municipal governments planning and implementing urban forest management programs is rising, as the benefits of urban forest ecosystems are becoming common knowledge. However, the urban forest is an exceedingly complex and vulnerable social–ecological system that presents a wide array of management challenges. One area of concern that is understudied and worthy of investigation is the effects of housing renovation activities and neighborhood revitalization on the urban forest. The purpose of this study is to investigate the possibility of renovation activity as a significant source of disturbance in urban forest ecosystems. We conducted ordinary least squares regression and geographically weighted regression analyses using canopy cover, building permit data, and socioeconomic variables in Toronto, Canada. We then conducted a parcel-level assessment of tree mortality using ortho-imagery from 2003 and 2014 and government open data describing 16 years of renovation activity. Findings suggest that renovation activity, as indicated by building permit abundance, is a possible cause of tree mortality and subsequently a source of urban forest disturbance. Our findings also suggest that the relationship between renovation activity and canopy cover is highly complex, and is likely influenced by residential tree planting rates, land use mix, and different trajectories of urban change.

Full textAbstract:
Residential segregation between social groups has grown in European cities, while the housing sector has boomed in major cities since 2009. These two forces raise questions about the role of new housing construction in the growth of segregation. This article explores the sorting of both socio-economic and ethnic groups into three housing types: older, newer and renovated apartment buildings. We employ data from Tallinn, the capital city of Estonia, where new housing construction has been extensive during the past ten years. We link census data with building-level data for publicly subsidised and privately funded housing renovations, and we calculate segregation indices by housing type and construct a multinomial regression model. Results suggest that publicly subsidised housing renovation contributes to continued mixing of socio-economic (occupational) groups, while new housing construction and especially private renovation increase segregation between ethnic and occupational groups. Ethnic and occupational segregation interact most strongly in privately funded apartment building renovations primarily within central city historic neighbourhoods.

Full textAbstract:
As Chinese cities transition into a stage of stock development, the revitalization of industrial areas becomes increasingly crucial, serving as a pivotal factor in urban renewal. The renovation of old factory buildings is in full swing, and architects often rely on matured experience to produce several profile renovation schemes for selection during the renovation process. However, when dealing with a large number of factories, this task can consume a significant amount of manpower. In the era of maturing machine learning, this study, set against the backdrop of the renovation of old factory buildings in an industrial district, explores the potential application of deep learning technology in improving the efficiency of factory renovation. We establish a factory renovation profile generation model based on the generative adversarial networks (GANs), learning and generating design features for the renovation of factory building profiles. To ensure a balance between feasibility and creativity in the generated designs, this study employs various transformation techniques on each original profile image during dataset construction, creating mappings between the original profile images and various potential renovation schemes. Additionally, data augmentation techniques are applied to expand the dataset, and the trained models are validated and analyzed on the test set. This study demonstrates the significant potential of the GANs in factory renovation profile design, providing designers with richer reference solutions.

Journal of Social Science Humanities and Literature 7, no. 4 (August 29, 2024): 54–63. http://dx.doi.org/10.53469/jsshl.2024.07(04).10.
Full textAbstract:
To deeply analyze the specific renovation models used in the collective rental housing renovation projects in urban villages, along with the residents' satisfaction post- renovation, and to extract related insights, this study adopted field survey and literature review methods to comprehensively organize and identify the renovation models of collective rental housing in urban villages. Moreover, this research employed two quantitative methods: Factor analysis and structural equation modeling. By selecting yuanfen new village in shenzhen city as a case study, it conducted an empirical investigation into the factors affecting the residents' satisfaction with the renovation of collective rental housing in urban villages. The results indicated that the influencing factors are divided into three categories: Fairness in procedures and policy planning, economic benefits and repair compensations, and historical culture and community cohesion. All these factors significantly positively impact residents' satisfaction. Based on these findings, the study suggests that the government should ensure fairness, justice, and transparency in the decision-making process of the collective rental housing renovation projects, establish reasonable compensation mechanisms to balance economic interests, protect cultural heritage, and enhance community identity and cohesion.

Full textAbstract:
In the cities of post-industrialized countries, renovation is the main part of building construction activity and has a major urban impact. Measuring this ongoing phenomenon and its distribution is of great usefulness for municipality urban planning and public policies. In this context, it is essential to introduce tools and processes that can allow for describing and predict how building renovation evolves. Open databases have become a valuable resource for observing processes and interactions in urban context. Data-driven analysis methods were used to directly interact with open city data, thus aiming to propose an alternative building renovation approach based on data gathering, parametric modeling, and visualization. Kernel Density Estimation (KDE) is an efficient tool that overcomes incomplete data, as not all renovation is reported to city halls. This article presents a preliminary study on a method of measuring building renovation intensity using the city of Lisbon building permit alphanumerical and spatial database as a case study.

Full textAbstract:
With the progress of urbanization in China, the energy-saving renovation of a large number of existing buildings, especially old buildings, has become an important project for the green and low-carbon development of urban renewal. This paper takes the old brick school building in a university in Chengdu as an example. Through field research, the existing problems of the building are analyzed in detail in terms of building function, structure and appearance, and a detailed plan for functional upgrading, structural reinforcement and façade renovation is drawn up, taking into account the actual requirements and environmental status. In addition, solar photovoltaic technology is integrated into the renovation of the building’s pitched roof. Through modelling and analysis, the amount of solar energy captured by the photovoltaic roof is quantitatively simulated and the dynamic energy-saving potential of the renovation project under changing actual meteorological conditions is pre-evaluated. The preliminary results indicate that such green renovations can contribute to about 164,066 kWh annual solar energy collection and the self-use electricity from the PV roof accounts for 42–76% of total energy consumption, leading to about 60% building energy consumption conservation. The payback period of such a renovation program is assessed to be about 1.9 years, which is quite economically feasible considering the local energy tariff policy. This paper explores the feasibility and design direction of green and low-carbon renovation and upgrading of old buildings, which can provide a reference for the application of green and low-carbon renovation of local old buildings.

Full textAbstract:
The renovation of old residential communities not only meets the people’s aspirations for a better life, but also promotes the image of a city. However, unreasonable cost allocation in the renovation of old residential communities seriously impedes the multi-channel fundraising and progress of renovation. The general aim of this study was to construct a cost allocation model for the renovation of old residential communities, so as to address unreasonable cost allocation and speed up the renovation. With the government, home owners, and private sectors as the main participants and stakeholders, we constructed a cost allocation model for the renovation of old residential communities based on the structural equation model and the Shapley value. The structural equation model is used for indicator screening and weight computing, while the Shapley value is used for cost allocation. Then, we improved the cost allocation model based on the influencing factors that were screened out. This discovery will increase the cooperation between the government, home owners, and private sectors to fund the renovation of old residential communities, and further improve the progress of renovation of old residential communities. The study results show that by fully taking into account the degree of participation, the degree of risk sharing, the degree of value-added return, and the degree of resource input of participants, the improved cost allocation model makes the cost allocation more reasonable and fairer.

This article introduces a method for advancing environmental and social sustainability objectives in relation to home renovations laid out in European and Belgian policies. The comfort tool is an instrument that simultaneously addresses the energy efficiency and universal design aspects of a sustainable home renovation while being usable and meaningful to laymen homeowners and improving their communication with building professionals. It is based on recent research exploring a synergetic merging of energy efficiency and universal design in housing through the concept of indoor environmental comfort. It employs comfort as a way of intervening in the decision-making process for energy efficiency and universal design measures in home renovations. The comfort tool takes a user-centered approach and rests on an interdisciplinary set of theoretical constructs bringing together knowledge from psychology, nursing, design, and building sciences. Besides describing the method itself, the article lays out the theoretical underpinnings and motivations behind its development and discusses relevant future considerations for sustainable home renovations research and practice.

The Plan of 1758 for the reconstruction of Lisbon's Baixa Pombalina followed principles of unparalleled efficiency and regularity. The grid of rectangular urban blocks with pre-designed street façades had a lasting impact on urban identity. Today, the original features of the blocks of flats allow renovation strategies that address changes in domestic life and present-day comfort demands: making use of alcoves and the enfilade to address intimacy; turning kitchens into social areas; using multiple entrances for flat division; introducing lifts according to staircase design. Recent renovations show how the flats' original features contribute to unconventional flexible layouts adapted to contemporary living.

Full textAbstract:
Urban land use multi-objective optimization aims to achieve greater economic, social, and environmental benefits by the rational allocation and planning of urban land resources in space. However, not only land use reconstruction, but renovation, which has been neglected in most studies, is the main optimization direction of urban land use. Meanwhile, urban land use optimization is subject to cost constraints, so as to obtain a more practical optimization scheme. Thus, this paper evaluated the renovation and reconstruction costs of urban land use and proposed a cost-heuristic genetic algorithm (CHGA). The algorithm determined the selection probability of candidate optimization cells by considering the renovation and reconstruction costs of urban land and integrated the renovation and reconstruction costs to determine the direction of optimization so that the optimization model can more practically simulate the actual situation of urban planning. The reliability of this model was validated through its application in Shenzhen, China, demonstrating that it can reduce the cost consumption of the optimization process by 35.86% at the expense of sacrificing a small amount of economic benefits (1.18%). The balance of benefits and costs enhances the applicability of the proposed land use optimization method in mature, developed areas where it is difficult to demolish buildings that are constrained by costs.

Full textAbstract:
In the article, the international experience of renovating historical buildings is explored, with an emphasis on historic residential buildings.
The history of the emergence of the idea of renovating historical buildings abroad is investigated. The concept of organized architecture preservation emerged in Italy and quickly spread to other European countries in the early 19th century. With the growing interest in preserving architectural heritage, new renovation technologies and methods, as well as innovative funding schemes, were developed.
Financial programs and grants used in Europe and America to finance the restoration of historical buildings are highlighted. In the United States, there are numerous programs that provide financial support for the restoration and preservation of important historical buildings, including federal tax incentive programs for historic preservation, certified local government programs that offer financial assistance for building rehabilitation through state historic preservation offices, the Community Development Block Grant program administered by the Department of Housing and Urban Development, and financial assistance from the Federal Emergency Management Agency for the repair and reconstruction of historic buildings damaged by natural disasters. In Europe, each country has its own program for financing the renovation of historical buildings, for example, in Germany, there is the "Städtebaulicher Denkmalschutz" program, in France, there is "La Fondation du patrimoine," in the UK there is the "Heritage Lottery Fund," and in Sweden, there is the "Riksantikvarieämbetet" program, all of which provide funding for the renovation of historical buildings, including residential ones. Funding under these programs may come in the form of grants, interest-free loans, or tax credits.
The main methods of renovating historical buildings that are most commonly used in European and American countries have been identified. The method of renovation is determined by the condition of the building, its inclusion in a certain list of landmarks, the legislation of the country in which the renovation is carried out, etc. In particular, the following methods of renovation can be distinguished, which are used in practically all countries: superstructure, construction of new buildings on the site of historical ones, extension, increasing the energy efficiency of the building, renovation of the building, construction of underground parking.

Apartment houses in Japan now face many serious problems. Japanese society is aging, resulting in 1 or 2 elderly people now living in houses built for larger households consisting of 3 or more people. This has distorted the structure of the population residing in apartments, so they do not function as district communities. To ensure the future effective utilization of our housing stock, we must tackle one fundamental challenge, namely developing methods of flexibly upgrading the existing housing stock to respond to change of the makeup of the population of regional societies and to changing life styles. Housing production and supply systems that enable residents to personally plan and decide specifications must be introduced to establish infill upgrading as an effectively functioning part of the future housing market.

Full textAbstract:
Currently, urban renovation activities in China are booming. And promoting the renovation of public buildings is a key feature of urban renovation due to its large scale, high cost, and significant impact to the natural and social environment. To reduce the ambiguity and uncertainty in evaluating the potential for the renovation of existing public buildings, a renovation potential evaluation model integrating a game theory-based combination weighting method and cloud model theory is proposed. This paper constructs a comprehensive evaluation index system based on relevant standards and the literature. Game theory is used to optimize the weights obtained by AHP and entropy weight methods to obtain a combined weight. MATLAB programming is used to calculate the comprehensive cloud parameters of the evaluation index for the potential renovation of existing public buildings and therefore generate cloud Graphs. Through a case study in Nanjing, China, it was demonstrated that the combination weight cloud model can objectively reflect the relationship between the fuzziness and randomness of evaluation indicators for public building renovation potential. The visual expression of cloud Graphs can intuitively reflect the magnitude of renovation and renovation potential and the degree of uncertainty in evaluation results. The research result provides useful references for the sustainable utilization of building resources in the era of building.

Housing renovations have become an important part of the construction of living environments in China, and improving residential flexibility is an important way to facilitate renovations. This study focused on the adjustments of interior space and living function from the perspective of the application of flexible design strategies through two-stage surveys. The renovation contents and needs of 439 residents were statistically analyzed, an evaluation of design strategies was performed by 226 architects, and a correlation analysis was carried out based on the data. The results showed that the distribution of renovations was positively related to the renovation difficulty and could be summarized into four parts, viz., functional arrangement, device and pipeline, furniture and storage, and decorative details, while the willingness to renovate was related to living requirements. Twenty design strategies for improving housing flexibility were evaluated, and a statistical analysis was carried out on the flexibility assessment and adoption willingness provided by architects. In 14 of these strategies, the flexibility assessment affected the architects’ willingness to adopt the design (p < 0.05); however, the adoption willingness was affected by external factors in the other six strategies, such as cost control. In addition, the architects’ adoption willingness score was generally lower than their assessment score for the same strategy; thus, top-level guidance to promote the application of flexible strategies should be strengthened.

The relevance of this study is devoted to overcoming a complex of social, environmental and economic problems in urban planning associated with the effective use of former industrial territories and the creation of public spaces with the preservation of architectural monuments. Foreign experience has shown the possibility of using former industrial areas through their renovation. Full use of all territories of the city ensures its integrity and connectivity of the transport system. Creation of new functions in buildings and on the territories of historical industrial enterprises, rethinking the architecture of industrial buildings (renovation, reconstruction and rehabilitation), which will lead to an influx of funds and investors, will make it possible to reproduce and maintain former industrial facilities at a new historical stage. Identifying ways to harmonize and develop the urban environment through the renovation of industrial areas is one of the urgent tasks in the formation of the concept of sustainable development of the city. Recommendations are presented for the implementation of the renovation of industrial territories, an analysis of the existing experience in the renovation of industrial territories, trends in the further development of their architectural and planning structure are revealed. The main aspects of the renovation of industrial territories are given, which will allow creating a more comfortable urban environment, developing social infrastructure and convenient public spaces. Industrial areas and former factory and factory buildings that are being renovated have a number of features that make it possible to use these features as an aid to new opportunities. Former industrial territories are often located in the central parts of cities and by activating these territories, this area can bring income to the economy, improve the environment, and itself provide comfort for each resident.

Full textAbstract:
The renovation and utilization of industrial heritage are important issues in the field of sustainable urban renewal. The renovation of industrial heritage is influenced by various factors such as the value of a heritage site, its location, the positioning of renovation, and the cost of renovation. Most existing studies focus on the concept of renovation and the establishment of heritage management techniques. However, a low cost in the context of urban sustainability has a greater impact on renovation. Therefore, this paper takes Beijing Xinhua 1949 Cultural and Creative Industrial Park as an example, incorporates the cost–benefit ratio into the plans for a low-cost construction, and proposes a method to evaluate the performance of holistic low-cost construction during the whole life cycle of industrial heritage renovation and utilization. This study uses the AHP method to create an evaluation index system and fuzzy TOPSIS(FTOPSIS) to rank the solutions so as to establish a comprehensive evaluation system to thus evaluate industrial heritage renovation projects that are difficult to fully quantify, with the aim to obtain performance evaluation conclusions. The results of this study suggest that the definition of a low-cost renovation should not be limited to a reduction in investment costs but should also pay equal attention to the cost–benefit ratio before and after renovation, and that functional and spatial sustainability is another feasible strategy for achieving the sustainable renovation of industrial heritage.

Introduction. Following any war, the destruction of cities causes severe damage to the lives of citizens, so urban planning and accelerating the process of renovation and development of a city is the priority of every country after the war, in order to reduce the damage caused by war. Since then, citizens can resume their normal living in their hometowns. The process of urban renovation and development takes a long time, and the main urban indicators should be regularly evaluated in different dimensions to find out whether the living environment has improved and the preset urban goals have been achieved.
Materials and methods. In this study, the process of renovation and development of the city of Homs was analyzed by evaluating the pre-selected social and economic indicators. The sign test and the Wilcoxon test were used to evaluate and compare the indicators before and after the war.
Results. The results of the research show that the null hypothesis of this research was rejected with a z-value of –3.137916 and a p-value of 0.002 in respect of the social dimension. Also, the zero hypothesis of this research is rejected in the economic dimension according to the results of the Wilcoxon test. The results show that the z-value is equal to –2.075 and the p-value is equal to 0.038, which is less than 0.50 and, hence, insignificant. The rejection of the null hypothesis and the large number of negative indicators in the social dimension indicate that the process of renovation and development of the city of Homs is very slow after the war and the city has not been able to approach the desired stable condition.
Conclusions. This research has found that only 11 indicators out of 45 improved in the process of renovation and development of the city of Homs after the war if compared to the pre-war period. In fact, more than 75 % of selected indicators were negative, and this shows the slow pace of urban renovation and development with an emphasis on the sustainable city of Homs.

We aimed to identify the characteristics of the changes in the buildings and alleyways in Yeonnam-dong, Seoul, where low-rise, residential buildings are being renovated or repurposed into commercial buildings, as well as to investigate their renovations, repurposes, and sociocultural implications. Thus, we surveyed and classified 149 renovated buildings, investigated the perceptions and ambiance of the area and buildings using a trade area analysis and interviews with visitors and store owners, and uncovered the importance of renovation. Since the early gentrification, a trend of performing renovations that retained the original form of the building from the initial renovation stage was seen; this created an ambiance of nostalgia, naturalness, and authenticity, along with the urban conditions of low-rise, residential buildings in Yeonnam-dong, a representative undeveloped area. These renovated buildings reflect the social status, taste, and practice of gentrifiers, and they reveal a hybridization of the past and present, Korean circumstances and exotic cultures, and residential and commercial buildings. As commercialization progressed, renovated buildings vastly differing from the original and displaying active commercial characteristics were seen. Our findings imply that the area’s early ambiance, which had an air of “distinctiveness”, has lost its personality and begun to generalize. Thus, numerous gentrifiers have been replaced and several aspects of renovation have changed that the visitors are aware of.

Full textAbstract:
Climate change is the main cause of frequent extreme weather and natural disasters. Therefore, effective climate adaptation strategies for urban rail transit (URT) should be adopted to cope with extreme precipitation events (EPEs). This study proposes a decision-making model based on climate change for drainage renovation, which consists of an optimal renovation sequence model and an optimal investment timing model. This study analyzes the inundation risk of each station and its node importance in the URT network and then uses a multi-attribute decision analysis (MADA) to determine the optimal renovation sequence. This study also uses a real options pricing approach to calculate the value of an option in order to defer the renovation project and determine the optimal investment timing. Then, the Beijing Urban Rail Transit (BURT) is taken as an example to conduct an empirical analysis of the proposed model. Considering the uncertainty of climate change and the complexity of the URT network, the model can obtain the optimal renovation sequence and the investment timing of each station, which is expected to provide a decision-making tool for urban governments to formulate an optimal plan that strengthens the prevention of flooding disasters.

Large cities are multifaceted organisms. They are arena of social and urban conflicts. In current conditions of technological development and improvement of the urban environment quality, local authorities are increasingly reorganize industrial areas.
The relevance of the article is determined by the global trend of finding new forms of renovation of depressed areas, which are explored quite well and reflected in the general vector of policy of developed countries. According to the research, it is ecological and urban forms of renovation that can ensure the efficient use of resources and create quality conditions to improve the living standard of population.
The purpose of the article is to establish ecological and urban forms of renovation of industrial areas.
The article substantiates the term "ecological and urban renovation", which main principle is to open new opportunities for depressed areas and buildings in order to improve the ecological and urban situation of the environment. Methods and approaches to the ecological and urban planning form of renovation of depressed areas are described. This allows adapting industrial architecture to modern urban conditions with a numerous architectural techniques.
The study examines foreign experience of redevelopment of industrial territories in Barcelona (Spain), Berlin (Germany), London (UK), Paris (France), Copenhagen (Denmark). The analysis of global practice shows that the most successful examples of ecological and urban transformation of industrial areas are implemented through the principle of landscape design and methods of integrating elements of industrial heritage into public space.
Consequently, by means of landscape design, the art space as a new phenomenon in the urban environment is created, which improves the aesthetic perception of the architectural city image. The experience has shown that industrial areas, which are located within the city, should be used for recreational and commercial facilities or residential real estate, whereas the areas near the city could be used for high-tech and environmentally-friendly industries.

Despite the fact that specialists from the economic, social and architectural fields of sciences have studied the topic, there is still ambiguity in solving the following issues: renovation strategy in the country; the possibility of residential buildings' renovation; types of residential buildings to be renovated. As a result of a comparative analysis of design materials, literary sources and statistical data, the authors determined the classification of multi-apartment residential buildings of mass series in the Republic of Kazakhstan. This classification combines the chronological order of construction, the type of structural scheme of buildings and the name of the series of residential buildings. The systematization of statistical data of the housing stock by various parameters made it possible to identify, with a small error, the proportion of multi-apartment housing subject to renovation. In addition, this work generally reveals the problem of renovation in the country related to the structure of the housing stock, the peculiarity of housing and communal services and the process of architectural and urban planning design.

The article analyzes modern trends of organization, development and renovation of hydroparks (;), identified functional planning methods hydroparks renovation (;) for the further creation of a single recreational network of the urban ecological framework. The study revealed problematic aspects related to the organization of riverside urban space, analyzed the natural and recreational potential and the current state of hydroparks (;). The formation and renovation (;) factors of recreational areas with water object were identified. The development of a park system in modern city to harmonize people’s relationships with nature, as well as to improve the conditions for people’s full recreation is a rather urgent strategic task of the state’s socio-economic policy.
An actual problem is the inconsistency of hydroparks (;) with the modern needs of the city’s residents and the insufficient level of attention to their development. Therefore, the main requirement for the development of recreational complexes with water objects, namely the goal is the formation of methods for the organization and rehabilitation of hydroparks (;) in the city structure. First of all, it is necessary to emphasize the urban planning significance of water object and other natural structures for the recreational functions of the city as a whole. The main principles of the organization and renovation of hydroparks (;): the formation of a comfortable environment, multifunctionality, the principle of complex renovation, compliance with socio-economic requirements. One of the possible ways of complex renovation is the use of three main principles – the rationality of the planning structure, the usefulness of the functional organization and the beauty of architectural and town-planning forms. All components form the integrity of the architectural and urban planning space. Thus, the search for a balance between anthropogenic and natural factors of the urban space contributes to the humanization of the spatial environment in the concept of sustainable development of the city.

Nowadays, in the context of smart city construction, the changes brought by the smart system to the city are not only material intelligence, but also because the smart system is completed by the cooperation of human wisdom and the wisdom of things, it is even more enhanced. There are various connections between people and people and cities. In this paper, the construction of urban parks, its management, and service requirements also show a trend of diversified development. However, some traditional urban parks cannot meet the new social needs. The application of smart park systems in their renovation is an important way for urban parks to rejuvenate and is an indispensable part of smart city construction. For urban parks, the upgrade of smartization in the traditional park model is not only an inevitable trend in the development of information technology but also an important direction for the future construction of parks. The purpose of this paper is to study and discuss the systematic methods applied by the smart park system in the renovation and renewal of urban parks, to discuss the common problems and solutions faced in the renovation and renewal of urban parks today, and to realize the renovation of the smart park system of urban parks. And by studying the application background, ways, and needs of the smart park system, it will carry out practical exploration on the renovation and renewal of Wuhan Jiefang Park. Through the analysis of the current situation of the Jiefang Park and the interpretation of the existing problems, special transformation is carried out under the guidance of the smart park system according to the existing problems, and the methods and systems of the application of the smart park system are summarized through practice. From a practical point of view, the update design strategy proposed in this paper is tested.

Children spend the majority of their time indoors, and a substantial portion of this time in the school environment. Air pollution has been shown to adversely impact lung development and has effects that extend beyond respiratory health. The goal of this study was to evaluate the indoor environment in public schools in the context of an ongoing urban renovation program to investigate the impact of school building renovation and replacement on indoor air quality. Indoor air quality (CO2, PM2.5, CO, and temperature) was assessed for two weeks during fall, winter, and spring seasons in 29 urban public schools between December 2015 and March 2020. Seven schools had pre- and post-renovation data available. Linear mixed models were used to examine changes in air quality outcomes by renovation status in the seven schools with pre- and post-renovation data. Prior to renovation, indoor CO measurements were within World Health Organization (WHO) guidelines, and indoor PM2.5 measurements rarely exceeded them. Within the seven schools with pre- and post-renovation data, over 30% of indoor CO2 measurements and over 50% of indoor temperatures exceeded recommended guidelines from the American Society of Heating, Refrigerating, and Air Conditioning Engineers. Following renovation, 10% of indoor CO2 measurements and 28% of indoor temperatures fell outside of the recommended ranges. Linear mixed models showed significant improvement in CO2, indoor PM2.5, and CO following school renovation. Even among schools that generally met recommendations on key guidelines, school renovation improved the indoor air quality. Our findings suggest that school renovation may benefit communities of children, particularly those in low-income areas with aging school infrastructure, through improvements in the indoor environment.

Compared with developed countries, the research on modern urban renewal in China is relatively late. However, with the landing of more and more projects in recent years, since Guangzhou, Shenzhen and other places took the lead in urban renewal, urban renewal has gradually entered a period of market-oriented and diversified operation. In recent years, under the influence of urban renewal strategy, the construction of old residential renovation projects is in full swing. In order to reduce the risk of construction, the construction unit often selects EPC project general contracting mode as the contract form of old residential renovation projects. However, the EPC project general contracting mode not only reduces the investment risk of the construction unit, but also greatly improves the difficulty of the general contracting unit's cost management of the renovation project of the old residential area. In order to complete the renovation project of the old residential area within the range of the budget estimate approved by the government and obtain the expected social benefits, cost management has become the control point of the project management of the EPC project general contractor. Based on the perspective of the general contractor, this paper takes the renovation project of the old residential area under EPC mode as the research object, uses AHP and fuzzy comprehensive evaluation method to evaluate the project cost management, analyzes the deficiencies in the actual cost management and puts forward countermeasures and suggestions.
