Full textAbstract:
Life cycle assessment (LCA) has become an international recognized method to estimate the environmental impacts of a building during its life. A building’s environmental impacts can be divided into two parts－impacts in the service stage and impacts in other stages of its life cycle. Other stages comprise material acquisition stage, constructing stage and final disposal stage. In life cycle except service stage, the LCA analysis was made on a timber structure teaching building using Athena software Eco-calculator. Then the teaching building is assumed to be redesigned adopting the structure of RC-frame and steel frame respectively. And the LCA analysis was made on the two assumed buildings too. By comparing the results, the conclusion can be drawn that timber buildings have lower environmental impact indexes compared with that of RC-frame and about the same with that of steel structure. The aboard usage of the timber structure instead of RC-frame structure can result in good environment performance. In service stage, if a sensible thermal insulation scheme is also considered, a great amount of energy will be saved, and the environmental impact of a building can be made minimum.

Full textAbstract:
The whole life cycle carbon emission of buildings was calculated in this paper. Based on the whole life cycle evaluation theory, a carbon emission calculation model was established by using a single urban building as an example. The whole life cycle building of carbon emission calculation includes five stages: planning and design, building materials preparation, construction, operational maintenance, as well as dismantlement. It provides a reference for standardizing the calculation process of building carbon emissions by analyzed the carbon emissions and composition characteristics of each stage of the life cycle of the case house. The calculation results demonstrate that the carbon emission during the operational maintenance and building materials preparation stages in the whole life cycle of the building account for 78.05% and 20.59% respectively. These are the two stages with the greatest emission reduction potential.

Green Building rating tools are the essential need of this era, to cope up with the sustainable development goals, climate change, and natural resource degradation through buildings. Realization of green building incentives decently increased within past few decades with abrupt declination in real estate markets and economic depletion has decelerated the interest of investors towards the green building projects. This research calculates influence of costing elements in MyCREST (IS-design) using questionnaire survey distributed amongst qualified professionals (QP’S) of green buildings and expert practitioners. Firstly, factor score and then weightage factor was performed to produce the final result with weightage output for evaluating weighatge and ranking of the relevant criteria of MyCREST and life cycle cost elements respectively. It is found that the criteria of storm water management has weighatge of 0.236 as highest and criteria environmental management plan (EMP) as 0.061 as lowest. Research also identified another perspective by finding association of cost element at design stage of MyCREST and found that management cost is highly associated at design stage with the value of 87.7%. The outcome of this research will add value to green building development and map road towards sustainable development using green building tools to uplift quality of life. Furthermore, this paves a way to integrate various stages of MyCREST with life cycle costing tool to potentially contribute in evaluating cost association through green building rating tool.

Full textAbstract:
Energy consumption and pollutant emissions from buildings have caused serious impacts on the environment. Currently, research on building environmental costs is quite insufficient. Based on life cycle inventory of building materials, fossil fuel and electricity power, a calculating model for environmental costs during different stages is presented. A single-objective optimization model is generated by converting environmental impact into environmental cost, with the same unit with direct cost. Two residential buildings, one located in Beijing and another in Xiamen, China, are taken as the case studies and analyzed to test the proposed model. Moreover, data uncertainty and sensitivity analysis of key parameters, including the discount rate and the unit virtual abatement costs of pollutants, are also conducted. The analysis results show that the environmental cost accounts for about 16% of direct cost. The environmental degradation cost accounts for about 70% of the total environmental cost. According to the probabilistic uncertainty analysis results, the coefficient of variation of material production stage is the largest. The sensitivity analysis results indicate that the unit virtual abatement cost of CO2 has the largest influence on the final environmental cost.

Full textAbstract:
Life Cycle Assessment (LCA), developed over 30 years ago, has been helpful in addressing a growing concern about the direct and indirect environmental impact of buildings over their lifetime. However, lack of reliable, available, comparable and consistent information on the life cycle environmental performance of buildings makes it very difficult for architects and engineers to apply this method in the early stages of building design when the most important decisions in relation to a building’s environmental impact are made. The LCA quantification method with need of employing complex tools and an enormous amount of data is unfeasible for small or individual building projects. This study discusses the possibility of the development of a tool that allows building designers to more easily apply the logic of LCA at the early design stage. Minimising data requirements and identifying the most effective parameters that promise to make the most difference, are the key points of simplification method. The conventional LCA framework and knowledge-based system are employed through the simplification process. Results of previous LCA studies in Australia are used as the specific knowledge that enable the system to generate outputs based on the user’s inputs.Keywords: Life Cycle Assessment (LCA), early design stage, most effective parameters, life cycle environmental performance

Full textAbstract:
Exiting green building assessment standards sometimes cannot work well for large-scale public buildings due to insufficient attention to the operation and maintenance stage. This paper combines the theory of life cycle assessment (LCA) and building information modeling (BIM) technology, thereby proposing a green building assessment method by calculating the greenhouse gas emissions (GGE) of buildings from cradle to grave. Life cycle GGE (LCGGE) can be divided into three parts, including the materialization stage, the operation and maintenance stage, and the demolition stage. Two pieces of BIM software (Revit and Designbuilder) are applied in this study. A museum in Guangdong, China, with a hot summer and warm winter is selected for a case study. The results show that BIM can provide a rich source of needed engineering information for LCA. In addition, the operation and maintenance stage plays the most important role in the GGE reduction of a building throughout the whole life cycle. This research contributes to the knowledge body concerning green buildings and sustainable construction. It helps to achieve the reduction of GGE over the whole life cycle of a building. This is pertinent to contractors, homebuyers, and governments who are constantly seeking ways to achieve a low-carbon economy.

The last few decades have witnessed a rapid development of green buildings in China especially the office sector. The life cycle assessment (LCA) approach has potential to weigh the benefits and costs associated with green building developments. Essentially, the LCA method evaluates the costs and benefits across a building's life cycle with a system approach. In this study, a green office building in Beijing, China, was analyzed by life cycle assessment to quantify its energy use and evaluate the environmental impacts in each life cycle stage. The environmental impacts can be reduced by 7.3%, 1.6% and 0.8% by using 30% gas-fired electricity generation, increasing the summer indoor temperature by 1°C, and switching off office equipment and lighting during lunchtime, respectively. Similarly, by reusing 80% of the selected materials when the building is finally demolished, the three major adverse environmental impacts on human health, ecosystem quality, and resource depletion can be reduced by 11.3% 12.7%, and 7.1% respectively. Sensitivity analysis shows that electricity conservation is more effective than materials efficiency in terms of a reduction in environmental impacts. These findings are useful to inform decision makers in different stages of the green building life cycle.

India is a rapidly growing economy witnessing continuous growth in the housing sector and living standards. The main focus of construction practices still remains on the architectural aspects of the buildings, largely unconcerned with their environmental impacts. The current thrust of concern for building sector, especially in developing countries, is to assess the environmental impact of buildings in a quantifiable way for implementing sustainable measures and achieving sustainability. Lifecycle assessment (LCA) is a comprehensive tool that is used worldwide to assess the environmental performance of any product or a process. This paper assesses the environmental impact of a residential house at planning stage on the basis of lifecycle assessment (LCA) considering various stages of building like construction, operation (for service life) and demolition, and identifies the hot-spots in the form of building components, materials, and stages.

In the context of the general trend to accelerate change, the actual goal of scientific research in the field of construction is to analyze and design the stages of the life cycle of a construction object. The object of the study becomes the information model of the life cycle of the building. It is studied and modeled based on the concept of real estate development and using the methods of project analysis of the construction project. The widest possibilities for obtaining and analyzing data on the state of a construction object, as well as the possibilities of systematizing information flows and information modeling of different periods of its life cycle, are realized in the approach of BIM modeling of buildings and structures. With the help of BIM-modeling tools, mandatory stages and possible phases of the life cycle of a building object can be represented as hierarchically and sequentially related information flows, in which the attributes of each stage of the life cycle are formed under the influence of the preceding stages and of special factors for the considered stage. As a result, the project documentation should reflect the decisions aimed at providing the necessary conditions and opportunities for subsequent periods of the life cycle of the construction object, as well as the most adapted for the predicted changes and transformations for all future stages and phases. The analysis of characteristics and the developed structure of simple and complex construction works allows determining for each stage and phase of the life cycle of a construction object: interconnection of information flows, composition and content of the information model of the building required for the work of specialists.

Today the construction of green buildings is in full swing, and the concept of green goes deeply into the hearts of the people. However, practitioners in the construction industry often place the emphasis of green building construction on the stage of design and construction. They hardly realize that green building's operation stage is the most important part in the whole life cycle of the building. To build real green building, it also needs sustainable development in the operation stage. The appearing of BIM (Building Information Model) technique effectively solved this problem. Using BIM technique in operation stage can effectively promote work efficiency of the operation organization, improve quality of service to customers, reduce the occurrence of emergencies in building's operation stage, improve safety performance, reduce resources waste and then construct real green buildings.

Introduction. An approach to the development of the organizational-technological model of the life cycle of a medical facility building is presented. Buildings of medical organizations have a number of features in the design, construction and operation. The buildings of nuclear medicine are subject to particularly high requirements of radiation and fire safety. Materials and methods. To organize the design, construction and maintenance of medical buildings, it is advisable to create and develop an organizational and technological model of the medical building life cycle. Such model was created by the author in the form of a business processes sequence. Confirmation of the effectiveness of the model is carried out with the help of multi-criteria expert evaluation. Results. To solve this problem, it is proposed a number of changes in the order of the investment project carrying. A new element is the Preliminary justification of the requirements for the health facility. It should become a mandatory document when obtaining a town-planning plan of the ground area, which is in Russia a de facto permission to design. It is also proposed to prepare technical requirements of three levels. The first level requirements are used for pre-design stage procedures. The requirements of the second level are included in the medical and technical design assignment. The requirements of the third level are applied to the detailed design, as well as to the construction and maintenance of the facility. Requirements are included in the requirement system and must be checked at key stages of the project. At the preliminary project phase, it is also advisable to make a technical and economic calculation with the justification of the main technical solutions and technical and economic indicators. This document should also include a project management plan. New elements are included in organizational and technological models of different stages of the object life cycle. Conclusions. On the basis of the developed model, it is proposed to make adjustments to the normative guideline used in the construction management. For example, it is necessary to make mandatory documents of the pre-design stage. These works have to be paid by investor therefore the standard of design cost has to be increased.

In the building industry, decreasing the CO2 emission not only is an important environmental issue but also an international responsibility in the future. This research analyzed building life cycle CO2 emission and used a building life cycle CO2 emission index (LCCO2). LCCO2 allows us to compare the impacts of different building designs to the environment and finds out the most efficient CO2 reduction strategy. A low floor house life cycle simulation showed that most CO2 emission in the life cycle comes from the daily use stage. Therefore, energy preservation in the daily life is the most important strategy to reduce CO2 emission in a building. Compared with the RC house, the light weight steel house uses more eco-friendly building materials and heat preservation materials. Therefore, the LCCO2 of the light weight steel house is reduced 31.34%. The research also showed that proper increase in the life span of the building also decreases CO2 emission. The light weight steel house is more eco-friendly than the RC house in the buildings life cycle.

In the conditions of rapid scientific and technological progress, the technologies development pace of designing buildings and structures began to outstrip the practical application of them in the domestic market in comparison with the countries of the western world. Ukrainian building design tools have ceased to be internationally competitive. In these circumstances, it is especially important to introduce new and improve existing methods and tools for modeling buildings and structures. An important task for a modern designer is the ability to use a computer model at various stages of the building's life cycle, namely: design, construction, operation. To solve this problem, one can apply a new design method - Building Information Modeling (BIM). The purpose of this research is to explore the possibilities of using information modeling technologies for buildings as a means of their life cycle managing. The scientific and practical importance of the work stands in the possibility of introducing of information modeling technologies of buildings not only as a new design method, but also as a means of managing of the life cycle of the building at all its stages. The results of the research are based on the analysis of literary sources and practical experience of the authors. The article revealed the possibility usage of building information modeling as means of managing of the life cycle of building and structures. There is considered options and the main problems of information modeling application on different stages of buildings life cycle. In this paper, the main functions of building information modeling, which are necessary for managing of the life cycle of buildings and structures, have been analyzed and formulated. The practical importance of the results of this paper is in the presentation of the proposed functions and development prospects of building information modeling tools.

Building performance evaluation is generally carried out through a non-automated process, where computational models are iteratively built and simulated, and their energy demand is calculated. This study presents a computational tool that automates the generation of optimal building designs in respect of their Life Cycle Carbon Footprint (LCCF) and Life Cycle Costs (LCC). This is achieved by an integration of three computational concepts: (a) A designated space-allocation generative-design application, (b) Using building geometry as a parameter in NSGA-II optimization and (c) Life Cycle performance (embodied carbon and operational carbon, through the use of thermal simulations for LCCF and LCC calculation). Examining the generation of a two-storey terrace house building, located in London, UK, the study shows that a set of building parameters combinations that resulted with a pareto front of near-optimal buildings, in terms of LCCF and LCC, could be identified by using the tool. The study shows that 80% of the optimal building’s LCCF are related to the building operational stage (σ = 2), while 77% of the building’s LCC is related to the initial capital investment (σ = 2). Analysis further suggests that space heating is the largest contributor to the building’s emissions, while it has a relatively low impact on costs. Examining the optimal building in terms compliance requirements (the building with the best operational performance), the study demonstrated how this building performs poorly in terms of Life Cycle performance. The paper further presents an analysis of various life-cycle aspects, for example, a year-by-year performance breakdown, and an investigation into operational and embodied carbon emissions.

Development in the direction of supporting the process of building construction: from the moment of the idea of its construction to complete dismantling, the BIM concept also included economic and planned components. At the present stage, the information model should develop and live with the building, even after putting it into operation. The purpose of this study is to analyze the maturity level of BIM solutions in accordance with the current development of BIM technologies at all stages of the building's life cycle. The stages of creating a model are distinguished: drawing up technical specifications for designing, performing engineering surveys, compiling 3 types of information models in accordance with the requirements for the development of the relevant sections of project documentation. The stages of the BIM-model life cycle that need to be improved are identified: operation, dismantling of buildings. The features of compiling information models, existing BIM solutions from various software manufacturers are considered. The comparison of existing BIM-solutions at all stages of creating an information model. For the analysis of BIM solutions, an expert assessment method will be used. A list of indicators and their rating weight for the methodology of expert evaluations is compiled. An assessment of the maturity of BIM-solutions. As a result of the analysis, a graph was compiled that clearly demonstrates the degree of maturity of the information model for the life cycle. The average percentage of development as a result of the assessment is determined. Some BIM solutions raise the question of the appropriateness of their use in the field of BIM technologies.

Full textAbstract:
This paper develops a life cycle assessment framework for embodied environmental impacts of building construction systems. The framework is intended to be used early in the design stage to assist decision making in identifying sources of higher embodied impacts and in selecting sustainable design alternatives. The framework covers commonly used building construction systems such as reinforced concrete construction (RCC), hot-rolled steel construction (HRS), and light steel construction (LSC). The system boundary is defined for the framework from cradle-to-grave plus recycling and reuse possibilities. Building Information Modeling (BIM) and life cycle assessment are integrated in the developed framework to evaluate life cycle embodied energy and embodied greenhouse emissions of design options. The life cycle inventory data used to develop the framework were extracted from BIM models for the building material quantities, verified Environmental Product Declarations (EPD) for the material production stage, and the design of construction operations for the construction and end-of-life stages. Application of the developed framework to a case study of a university building revealed the following results. The material production stage had the highest contribution to embodied impacts, reaching about 90%. Compared with the conventional RCC construction system, the HRS construction system had 41% more life cycle embodied energy, while the LSC construction system had 34% less life cycle embodied energy. When each system was credited with the net benefits resulting from possible recycling/reuse beyond building life, the HRS construction system had 10% less life cycle embodied energy, while the LSC construction system had 68% less life cycle embodied energy. Similarly, the HRS construction system had 29% less life cycle greenhouse gas (GHG) emissions, while the LSC construction system had 62% less life cycle GHG emissions. Sustainability assessment results showed that the RCC construction system received zero Leadership in Energy and Environmental Design (LEED) credit points, the HRS construction system received three LEED credit points, while the LSC construction system received five LEED credit points.

Global construction industry has a huge influence on world primary energy consumption, spending, and greenhouse gas (GHGs) emissions. To better understand these factors for mass timber construction, this work quantified the life cycle environmental and economic performances of a high-rise mass timber building in U.S. Pacific Northwest region through the use of life-cycle assessment (LCA) and life-cycle cost analysis (LCCA). Using the TRACI impact category method, the cradle-to-grave LCA results showed better environmental performances for the mass timber building relative to conventional concrete building, with 3153 kg CO2-eq per m2 floor area compared to 3203 CO2-eq per m2 floor area, respectively. Over 90% of GHGs emissions occur at the operational stage with a 60-year study period. The end-of-life recycling of mass timber could provide carbon offset of 364 kg CO2-eq per m2 floor that lowers the GHG emissions of the mass timber building to a total 12% lower GHGs emissions than concrete building. The LCCA results showed that mass timber building had total life cycle cost of $3976 per m2 floor area that was 9.6% higher than concrete building, driven mainly by upfront construction costs related to the mass timber material. Uncertainty analysis of mass timber product pricing provided a pathway for builders to make mass timber buildings cost competitive.

Full textAbstract:
The building sector is one of the most relevant in terms of generation of wealth and occupation, but it is also responsible for significant consumption of natural resources and the generation of environmental impacts, mainly greenhouse gas emissions. In order to improve the eco profile of buildings during their life-cycle, the reduction of the use of resources and the minimization of environmental impacts have become, in the last years, some of the main objectives to achieve in the design of sustainable buildings. The application of the life-cycle thinking approach, looking at the whole life cycle of buildings, is of paramount importance for a real decarbonization and reduction of the environmental impacts of the building sector. This paper presents an application of the life-cycle assessment methodology for assessing the energy and environmental life-cycle impacts of a single-family house located in the Mediterranean area in order to identify the building components and life-cycle steps that are responsible of the higher burdens. The assessment showed that the largest impacts are located in the use stage; energy for heating is significant but not dominant, while the contribution of electricity utilized for households and other equipment resulted very relevant. High environmental impacts are also due to manufacture and transport of building materials and components.

Construction is a crucial sector in terms of worldwide environmental impacts. Building material production along with transport and demolition are no exception, because in the last decades, they have constantly increased their carbon dioxide (CO2) emissions. Actions and initiatives are therefore important to tackle the relationship between buildings and climate change. Particularly, it is necessary to develop Life Cycle Assessment (LCA) tools useful to calculate the environmental impact of buildings and to make them accessible to designers and stakeholders acting in the building sector. The article aims to contribute to the international debate about environmental assessment indicators for buildings and the simplified LCA based tools. The Embodied Energy (EE) and the Embodied Carbon (EC) have been investigated. The former, related to primary energy content; the latter, associated with the equivalent carbon dioxide emissions. EE and EC have been used as indicators for the development of a calculation tool named EURECA, for assessing the environmental impact of the building over its life cycle, as defined by the EN 15978:2011 standard. The Solar Decathlon Latin America and Caribbean’s house designed and built by an international academic team has been an opportunity to check the indicators and the tool’s effectiveness.

Full textAbstract:
Digital twin (DT) or so-called ‘building information model (BIM)’ has brought great revolution to the current building industry. Its applications to life cycle management of buildings and infrastructures can further increase the social and economic benefits. As a complete information model, a digital twin integrates the information of a project from different stages of the life cycle into a model, in order to facilitate better asset management and communicate through data visualizations with participants. This paper unprecedently introduces a digital-twin aided life cycle assessment to evaluate a subway station. Dadongmen subway station in Hefei was used as a case study. This new study benchmarks the cost estimation and carbon emission at each life cycle stage of the project. The cost in the construction stage of the project is the highest, accounting for 78% of the total cost. However, the amount of carbon emissions in the operation and maintenance is higher than the amount during the production of building materials, accounting for 67%. Among them, concrete only accounts for 43.66% of the carbon emissions of building materials, even though concrete was mainly used for constructing the metro station. Steel bar and aluminum alloy have carbon emissions of 29.73% and 17.64%, respectively. In addition, emerging risks of the subway stations can be identified. The digital twin has been used to illustrate vulnerability and potential solutions to emerging risks, and to assess the suitability through life cycle cost and carbon footprint. This initiative is relatively new to the industry. The new insight into life cycle assessment or LCA (especially carbon footprint over the life cycle) integrated with digital twin applications will enable sustainable development that will enhance resilience of metro railway systems globally.

By connecting Project and Facility managements, the facility acquires a new method during the process management as early as in the initial stage of its life cycle. If a facility manager is engaged in these initial stages, in which parameters of a future facility are defined, he can use his experience and a different point of view to help architects, designers, investor and other participants in the building project avoid errors in design and operation collisions that would come out in implementation or exploitation stages. The aim of the paper is to refer to areas in which it could be possible to influence making decision on properties and parameters of a future facility in conceptual and designing stages and thereby ensure the improvement of the properties that will come out in the exploitation stage as a saving in uselessly expended investments due to errors in project preparation.

There is growing demand to develop methods that integrate environmental and economic assessment of more sustainable technologies incorporated into commercial and residential buildings. In this paper, we incorporate economic and energy use data obtained for a green roof operating in the Midwest U.S. at latitude 42.94N into an integrated approach to estimate and compare the economic and environmental impacts of an intensive (or extensive) green roof with a built-up roof. The life cycle stages included in the analysis were material acquisition life stage which including the transportation effects from material extraction through manufacturing to the finished products, and the use and maintenance life stage of the building. Environmental impact analysis indicates that green roof emits three times more environmental pollutants than built-up roofs in the material acquisition life stage. However, in the use and maintenance life stage, built-up roof emits three times more pollutants than a green roof. Overall, when emissions from both material acquisition life stage and use and maintenance life stage are combined, the built-up roof contributes almost 3 times more (or 46% more) environmental emissions than green roof over a 45-year building life span. Furthermore the overall energy use, specifically energy involved in the transportation from material extraction through to the finished product indicate that green roof uses 2.5 times less energy than a built-up roof. An Economic Input and Output life cycle assessment (EIO-LCA) was used to estimate the environmental impacts. The economic impact over an assumed 45-year building life was determined using life cycle costing, taking into account Net Present Value (NPV) calculations. Life cycle costing results indicate that green roof costs approximately 50% less to maintain over a 45 year-building life than a built-up roof. A Monte Carlo simulation is also performed to account for any variability in cost data. In addition, the paper presents a method to quantify the value incentive that a decision-maker has in adopting green technology. Results from the study indicate that when a green roof is compared to the Midwest regional NPV of a built-up roof, we find that the cost to maintain it ($35 per square foot) lies well below the average regional NPV of $59 per square foot of a built-up roof.

Using building information modeling (BIM) and Ecotect, this paper estimated carbon emissions during an office building’s life cycle. This building’s life cycle CO2emissions were divided into three parts: the construction, operation, and demolition stages. Among these, the statistics on the schedule of quantities were generated using BIM, and the energy consumption during the building’s operational stage was obtained using ECOTECT simulation. Sensitivity analysis was performed by changing several alternative parameters, to identify which parameter has more impacts on building performance. The paper demonstrated that (1) BIM and Ecotect are very helpful in estimating carbon emissions from a building’s life cycle, (2) the primary and effective measures to reduce the building’s CO2emissions in hot and humid climate should be arranged as follows: (a) within the limits of comfort, reducing the fresh air volume; (b) extending the indoor temperature range; (c) improving the thermal insulation performance of exterior windows, walls, and roofs; (d) exploiting natural ventilation during transition seasons, and (3) currently there are some limitations in performing LCA based on BIM and Ecotect.

Full textAbstract:
Envelope insulation and protection is an important technical solution to reduce energy consumption, exterior damage, and environmental impacts in buildings. Thermal insulation tiles are used simultaneously as thermal insulation of the building envelope and protection material of under layers in flat roofs systems. The purpose of this research is to assess the environmental impacts of the life cycle of thermal insulation tiles for flat roofs. This research presents the up-to-date “cradle to gate” environmental performance of thermal insulation tiles for the environmental categories and life-cycle stages defined in European standards on environmental evaluation of building. The results presented in this research were based on site-specific data from a Portuguese factory and resulted from a consistent methodology that is here fully described, including the raw materials extraction and production, and the modelling of energy and transport processes at the production stage of thermal insulation tiles. These results reflect the weight of the raw-materials within the production process of thermal insulation tiles in all environmental categories and show that some life cycle stages, such as transportation of raw materials (A2) and packaging and packaging waste (A3.1 and A3.3, respectively), may not be discarded in a cradle to gate study of a construction material because they can make a significant contribution to some environmental categories. Moreover, complementary results regarding the economic, environmental, and energy performance Life Cycle Assessment (LCA) of flat roofs solutions incorporating the thermal insulation tiles studied showed that the influence of the economic costs on the total aggregated costs of these solutions is much higher than that of the environmental costs due to the lower environmental costs of the thermal insulation tiles at the product stage (A1–A3). These costs influenced the corresponding percentage of the environmental costs (between 14% and 18%) and the percentage of the economic costs (between 70% and 75%) in the total aggregated (environmental, economic, and energy) net present value (NPV). Finally, a complementary “cradle to cradle” environmental LCA discussion is presented including the following additional life cycle stages: maintenance and replacement (B2–B4), operational energy use (B6), and end-of-life stage and benefits and loads beyond the system boundary (C1–C4 and D).

Purpose The purpose of this paper is to present an analysis of common parameters in existing tools that provide guidance to carry out Whole Building Life Cycle Assessment (WBLCA) and proposes a new taxonomy, a catalogue of parameters, for the definition of the goal and scope (G&S) in WBLCA. Design/methodology/approach A content analysis approach is used to identify, code and analyze parameters in existing WBLCA tools. Finally, a catalogue of parameters is organized into a new taxonomy. Findings In total, 650 distinct parameter names related to the definition of G&S from 16 WBLCAs tools available in North America, Europe and Australia are identified. Building on the analysis of existing taxonomies, a new taxonomy of 54 parameters is proposed in order to describe the G&S of WBLCA. Research limitations/implications The analysis of parameters in WBLCA tools does not include Green Building Rating Systems and is only limited to tools available in English. Practical implications This research is crucial in life cycle assessment (LCA) method harmonization and to serve as a stepping stone to the identification and categorization of parameters that could contribute to WBLCA comparison necessary to meet current global carbon goals. Social implications The proposed taxonomy enables architecture, engineering and construction practitioners to contribute to current WBLCA practice. Originality/value A study of common parameters in existing tools contributes to identifying the type of data that is required to describe buildings and contribute to build a standardized framework for LCA reporting, which would facilitate consistency across future studies and can serve as a checklist for practitioners when conducting the G&S stage of WBLCA.

Buildings produce a large amount of carbon emissions in their life cycle, which intensifies greenhouse-gas effects and has become a great threat to the survival of humans and other species. Although many previous studies shed light on the calculation of carbon emissions, a systematic analysis framework is still missing. Therefore, this study proposes an analysis framework of carbon emissions based on building information modeling (BIM) and life cycle assessment (LCA), which consists of four steps: (1) defining the boundary of carbon emissions in a life cycle; (2) establishing a carbon emission coefficients database for Chinese buildings and adopting Revit, GTJ2018, and Green Building Studio for inventory analysis; (3) calculating carbon emissions at each stage of the life cycle; and (4) explaining the calculation results of carbon emissions. The framework developed is validated using a case study of a hospital project, which is located in areas in Anhui, China with a hot summer and a cold winter. The results show that the reinforced concrete engineering contributes to the largest proportion of carbon emissions (around 49.64%) in the construction stage, and the HVAC (heating, ventilation, and air conditioning) generates the largest proportion (around 53.63%) in the operational stage. This study provides a practical reference for similar buildings in analogous areas and for additional insights on reducing carbon emissions in the future.

This article concerns the Life Cycle Assessment method of evaluation and the ways in which it can be applied as a tool facilitating the design of buildings to reduce embodied energy and embodied carbon. Three variants of a building were examined with the same functional ground plan and usable floor area of 142.6 m2. Each variant of the building was designed using different construction technologies: bricklaying technology utilizing autoclaved aerated concrete popular in Poland, wooden frame insulated with mineral wool, and the Straw-bale technology. Using digital models (Building Information Model) the building’s energy characteristics was simulated and the embodied energy and embodied carbon of the production stage (also called cradle-to-gate) were calculated. The performed calculations were used to compare the cumulative energy and embodied carbon of each variant for a 40 year long life cycle.

In Russia, Building Information Modeling (BIM) is becoming a mandatory requirement for the construction of new buildings. There is a positive experience in the implementation and examination of projects with BIM. A number of Russian companies have already introduced and are actively using information design technologies in their activities. However, at the current moment, the use of BIM in Russia is at the start. This paper shows examples of the use of BIM and laser scanning in the development of scientific and project documentation for cultural heritage sites. The paper shows the stages of engineering research. A comparison is made between traditional methods of building inspection and with the method of laser scanning. The key advantages of using a BIM model at the design stage, restoration and subsequent stages of the object’s life cycle are shown. The promising areas of application of BIM technologies, laser scanning technologies at different stages of the life cycle of an object (buildings, structures, utilities) have been identified.

Life Cycle Assessment (LCA) is an advantageous tool for the analysis of the overall environmental effects of a building. Most of the decisions that influence the final result of an LCA are made during the design process of the building. Therefore, LCA in early design stages is crucial, because the changes in this period of design are cheaper and more effective. However, there are many other aspects that influence the design of a building. During the design process a high number of variables have to be defined, and in each design stage a specific number of variables have to be fixed depending on various engineering considerations. In this paper we investigate the effect of decisions made in each design stage on LCA results. Within this paper the available possibilities are compared with the variant that was actually selected in each stage, and it is evaluated how environmental indicators evolve during the whole design process. The approach is demonstrated on a case study of a realized single family house.

Under the background of Chinese Rural Revitalization Strategy, how to improve rural regional environment and living quality is very important and urgent. At present, residential buildings in gully regions of the Loess Plateau have poor insulation and high-energy consumption. Thus, better ecological design can largely save energy and improve living comfort. The findings of this paper provide an insight into the ecological design potentials for reducing energy demand across rural regions in China. In this paper, we select three main types of residential buildings in gully regions and build energy demand models based on the Life Cycle Assessment (LCA) method. The results show that the energy demand in the building use stage is extremely high in all three typical buildings, which account for around 90% of the whole life cycle. The energy demand of the traditional adobe residential building is lower than the brick-concrete structure buildings. The LCA method used in this paper can quantify the energy demand in each stage of life cycle, which helps to put forward the corresponding ecological design strategy. The research results can be used as a reference in the future development of this region and other rural regions in China.

Full textAbstract:
Energy efficient buildings are viewed as one of the solutions to reduce carbon emissions from the built environment. However, studies worldwide indicate that there is a significant gap between building energy targets (as-designed) and the actual measured building energy consumption (as-built). Several underlying causes for the energy performance gap have been identified at all stages of the building life cycle. Focus is generally on the post-occupancy stage of the building life cycle. However, issues relating to the construction and commissioning stages of the building are a major concern, though not usually researched. There is uncertainty on how to address the as-designed versus as-built gap. The objective of this review article is to identify causes for the energy performance gap in buildings in relation to the post-design and pre-occupancy stages and review proposed solutions. The methodology applied in this research is the rapid review, which is a variant of the systematic literature review method. Findings suggest that causes for discrepancies between as-designed and as-built energy performance during the construction and commissioning stages relate to a lack of knowledge and skills, lack of communication between stakeholders and a lack of accountability for building performance post-occupancy. Recommendations to close this gap during this period include better training, improved communication standards, collaboration, energy evaluations based on post-occupancy performance, transparency of building performance, improved testing and verification and reviewed building standards.

Climate change, environmental degradation, and limited resources are motivations for sustainable forest management. Forests, the most abundant renewable resource on earth, used to make a wide variety of forest-based products for human consumption. To provide a scientific measure of a product’s sustainability and environmental performance, the life cycle assessment (LCA) method is used. This article provides a comprehensive review of environmental performances of forest-based products including traditional building products, emerging (mass-timber) building products and nanomaterials using attributional LCA. Across the supply chain, the product manufacturing life-cycle stage tends to have the largest environmental impacts. However, forest management activities and logistics tend to have the greatest economic impact. In addition, environmental trade-offs exist when regulating emissions as indicated by the latest traditional wood building product LCAs. Interpretation of these LCA results can guide new product development using biomaterials, future (mass) building systems and policy-making on mitigating climate change. Key challenges include handling of uncertainties in the supply chain and complex interactions of environment, material conversion, resource use for product production and quantifying the emissions released.

Energy conservation and human thermal comfort enhancement in buildings is a topical issue of modern architecture and construction. The innovative solution of this problem makes it possible to enhance building ecological and maintenance safety, to reduce hydrocarbon fuel consumption, and to improve life standard of people. The requirements to increase of energy efficiency in buildings should be provided at all the stages of building's life cycle that is at the stage of design, construction and maintenance of buildings. The research purpose is complex analysis of energy efficiency in operated high-rise residential building. Many actions for building energy efficiency are realized according to the project; mainly it is the effective building envelope and engineering systems. Based on results of measurements the energy indicators of the building during annual period have been calculated. The main reason of increase in heat losses consists in the raised infiltration of external air in the building through a building envelope owing to the increased air permeability of windows and balcony doors (construction defects). Thermorenovation of the building based on ventilating and infiltration heat losses reduction through a building envelope allows reducing annual energy consumption. Energy efficiency assessment based on the total annual energy consumption of building, including energy indices for heating and a ventilation, hot water supply and electricity supply, in comparison with heating is more complete. The account of various components in building energy balance completely corresponds to modern direction of researches on energy conservation and thermal comfort enhancement in buildings.

Urban population has been increased rapidly and caused such urban problems as shortage of housing and traffic jam, and the continuously expanding buildings have resulted in strong impact on global resource consumption and environmental pollution. Green building materials are the basic guarantee to the quality and service life of buildings, the material carrier to realize various functions of buildings and also the foundation and support to develop green buildings. Based on the coherence and relevance of assessment on full life cycle of buildings and building materials, the influence of exterior window selection on carbon emission of buildings was analyzed in aspects of the initial stage (production, consumption and transport of building materials) of carbon emission of buildings, i.e. the intrinsic energy per unit product, operation, demolition and treatment. The comprehensive assessment was also established, and the selection of green building materials was investigated for exterior windows based on the reduction of energy consumption during full life cycle of buildings by combining such indicators as the usability, durability, fireproofness, environmental protection and functionality of exterior windows. It solved the puzzles of architects on selection of building materials and the puzzles of building material manufacturers on demand of green buildings. The selection of green building materials on green buildings was promoted and the realization of the goal of "green buildings" also assisted.

What's more, it emphasized the importance of energy saving design at the stage of planning and design. Meanwhile, the paper not only analysed the whole life cycle energy saving contents and calculation formulas of large-scale public building by taking advantage of LCEA model, but also proposed some corresponding measures to save energy.

Purpose - to ensure sustainable development of the territory and incentives to increase the "green" building by improving the competitiveness of the buildings that have higher environmental and economic performance at all stages of the life cycle. A systematic analysis of standards of "green" building and the existing methodologies for life cycle assessment back. Developed and studied environmental-economic model of the life cycle of the building effectively, by identifying and organizing the quantitative and qualitative characteristics and to calculate the total cost of the building. These issues are discussed in this article.

The role of buildings in the context of addressing the consequences of climate change and the energy deficit is becoming increasingly important due to their share in the overall amount of green house gas (GHG) emissions and rapidly growing domestic energy consumption worldwide. Adherence to a sustainability agenda requires ever-increasing attention to all stages of a building′s life, as such approach allows for the consideration of environmental impacts of a building, from design, through construction stages, until the final phase of a building′s life—demolition. A life cycle assessment (LCA) is one of the most recognized and adopted models for the evaluation of the environmental performance of materials and processes. This paper aims to perform an LCA of four different types of residential buildings in Nur-Sultan, Kazakhstan. The assessment primarily considered embodied energy and GHG emissions as key assessment indicators. Findings suggest that the operational stage contributed to more than half of the GHG emissions in all the cases. The results of the study indicate that there is a dependence between the comfort levels and the impact of the buildings on the environment. The higher the comfort levels, the higher the impacts in terms of the CO2 equivalent. This conclusion is most likely to be related to the fact that the higher the comfort level, the higher the environmental cost of the materials. A similar correlation can be observed in the case of comparing building comfort levels and life-cycle impacts per user. There are fewer occupants per square meter as the comfort level increases. Furthermore, the obtained results suggest potential ways of reducing the overall environmental impact of the building envelope components.
