Abstract:

The move towards a de-carbonised world, driven partly by climate science and partly by the business opportunities it offers, will need the promotion of environmentally friendly alternatives, if an acceptable stabilisation level of atmospheric carbon dioxide is to be achieved. This requires the harnessing and use of natural resources that produce no air pollution or greenhouse gases and provides comfortable coexistence of human, livestock, and plants. The increased availability of reliable and efficient energy services stimulates new development alternatives. This paper focuses on and presents a comprehensive review of energy sources, and the development of sustainable technologies to explore these energy sources. The author investigates the potential renewable energy technologies, efficient energy systems, energy savings techniques and other mitigation measures necessary to reduce climate changes.

Abstract:

Urban environments can be key to sustainable energy in terms of driving innovation and action. Urban areas are responsible for a significant part of energy use and associated greenhouse gas emissions. The share of greenhouse gas emissions is likely to increase as global urban populations increase. As over half of the human population will live in cities in the near future, the management of energy supply and demand in urban environments will become essential. Developments such as the transformation of the electricity grid from a centralised to a decentralised system as well as the electrification of the transportation and heating systems in buildings will transform the urban energy landscape. Efficient heating systems, sustainable energy technologies, and electric vehicles will be critical to decarbonise cities. An overview of emerging technologies and concepts in the built environment is provided in this literature review on the basis of four main areas, namely, energy demand, supply, storage, and integration aspects. The Netherlands is used as a case study for demonstrating evidence-based results and feasibility of innovative urban energy solutions, as well as supportive policies.

Abstract:

Implementing energy-efficient solutions in a built environment is important for reaching international energy reduction targets. For advanced energy efficiency-related solutions, computer-based decision support systems are proposed and rapidly used in a variety of spheres relevant to a built environment. Present research proposes a novel artificial neural network-based decision support system for development of an energy-efficient built environment. The system was developed by integrating methods of the multiple criteria evaluation and multivariant design, determination of project utility and market value, and visual data mining by artificial neural networks. It enables a user to compose up to 100,000,000 combinations of the energy-efficient solutions, analyze strengths and weaknesses of a built environment projects, provide advice for stakeholders, and calculate market value and utility degree of the projects. For visual data mining, self-organizing maps (type neural networks) are used, which may influence the choosing of the final set of alternatives and criteria in the decision-making problem, taking into account the discovered similarities of alternatives or criteria. A system was validated by the real case study on the design of an energy-efficient individual house.

Abstract:

Green products, clean energy, energy union, green buildings, eco-innovations, environment-related, and similar initiatives and policies have become very popular and widely applied all over the world. A pleasant built environment (parks, flowerbeds, beautiful buildings) and a repulsive environment (noise, polluted surroundings) influence a buyer’s outlook on an advertisement differently. An aesthetic, comfortable, and clean built environment evokes positive emotional states, not only at the time of housing selection and purchase but during the building’s life cycle as well. Potential housing buyers always feel comfortable in certain built environments, and they are inclined to spend more time there. The issues needing answers are how to measure the segmentation/physiological indicators (crowd composition by gender and age groups), as well as the emotional (happy, sad, angry, valence) and physiological (heart rate) states of potential homebuyers realistically, to produce an integrated evaluation of such data and offer buyers rational, green, and energy efficient housing alternatives. To achieve this purpose, the Multisensory, green and energy efficient housing neuromarketing method was developed to generate the necessary conditions. Here, around 200 million multisensory data recordings (emotional and physiological states) were accumulated, and the environmental air pollution (CO, NO2, PM10, volatile organic compounds) and noise pollution were investigated. Specific green and energy efficient building case studies appear in this article to demonstrate the developed method clearly. The obtained research results are in line with those from previous and current studies, which state that the interrelation of environmental responsiveness and age forms an inverse U and that an interest in green and energy efficient housing depends on age.

Abstract:

Implementing renewables in the built environment represents a must, considering the target of Nearly Zero Energy Buildings set by the European legal frame, starting with 2020. One specific feature of the built environment is that it additionally imposes constraints, and can distort the renewable energy potential, particularly the wind energy. Therefore, the development of optimized, efficient small wind turbines requires on-site monitoring and, further on, models developed/adjusted according to these. Thus, the main purpose of this study is the analysis of the available wind potential in the built environment – particularly in the Colina Campus of the Transilvania University, in order to implement small wind energy conversion systems. Wind data are collected during one year (2013) from the meteorological station from Brasov - Ghimbav (located 8 km far from Brasov), and from a second weather station, which is mounted on the rooftop of the university building in Brasov city (University hill). The results indicate that the area has a promising wind potential for the implementation in this built environment of small-sized wind turbines, which can start operating from 0.8 m/s and producing electricity from min. 1.8 m/s.

Abstract:

International pressures through global agreements such as the recent Paris agreement in 2015 have put stress on governments and industries to find lasting solutions for the built environment. The built environment was recognized as an important factor in reducing global emissions for the first time at the Conference of Parties (COP) 21 meeting in Paris through a dedicated ‘Buildings Day.’ The Global Alliance for Buildings and Construction (GlobalABC) was also launched at COP 21 as a network to globally support zero emission, efficient and resilient buildings and construction sector. The Paris Agreement brought all nations to collectively combat climate change with a view to limit temperature increases to no more than 2 degrees Celsius (°C). Nations agreed to report their efforts through the monitoring program. In most countries, residential and commercial buildings spend a large proportion of their energy in lighting, heating, ventilation, air conditioning and in various appliances requiring energy for operation. This paper takes a broad understanding of zero energy. Starting with buildings, the definitions also consider understanding zero energy and from a carbon perspective, considering going from beyond buildings to include precincts and cities. The paper brings an understanding of zero energy, its importance, and its urgency with respect to global commitments to reduce the impact of the building and construction sector and the role of governments and industries in supporting the lowering of emissions in the built environment now and in the future.

Abstract:

Design strategies for sustainable buildings, that improve building performance and avoid extensive resource utilization, should also promote healthy indoor environments. The following paper contains a review of the couplings between (1) building design, (2) indoor environmental quality and (3) occupant behavior. The paper focuses on defining the limits of adaptation on the three aforementioned levels to ensure the energy efficiency of the whole system and healthy environments. The adaptation limits are described for measurable physical parameters and the relevant responsible human sensory systems, evaluating thermal comfort, visual comfort, indoor air quality and acoustical quality. The goal is to describe the interactions between the three levels where none is a passive participant, but rather an active agent of a wider human-built environment system. The conclusions are drawn in regard to the comfort of the occupant. The study reviews more than 300 sources, ranging from journals, books, conference proceedings, and reports complemented by a review of standards and directives.

Abstract:

The growing interest in biomimicry in built environments highlights the awareness raised among designers on the potentials nature offers to human and system function improvements. Biomimicry has been widely utilized in advanced material technology. However, its potential in sustainable architecture and construction has yet to be discussed in depth. Thus, this study offers a comprehensive review of the use of biomimicry in architecture and structural engineering. It also reviews the methods in which biomimicry assists in achieving efficient, sustainable built environments. The first part of this review paper introduces the concept of biomimicry historically and practically, discusses the use of biomimicry in design and architecture, provides a comprehensive overview of the potential and benefits of biomimicry in architecture, and explores how biomimicry can be utilized in building envelops. Then, in the second part, the integration of biomimicry in structural engineering and construction is thoroughly explained through several case studies. Finally, biomimicry in architectural and structural design of built environments in creating climate-sensitive and energy-efficient design is explained.

Abstract:

Current climate change threats and increasing CO2 emissions, especially from the building stock, represent a context where action is required. It is necessary to provide efficient manners to manage energy demand in buildings and contribute to a decarbonised future. By combining new technologies, such as artificial intelligence, Internet of things, blockchain, and the exploitation of big data towards solving real life problems, the way could be paved towards smart and energy-aware buildings. In this context, the aim of this paper is to present a critical review and an in-detail definition of the big data value chain for the built environment in Europe, covering multiple needs and perspectives: “policy”, “technology” and “business”, in order to explore the main challenges and opportunities in this area.

Abstract:

We analyze the diffusion of buildings certified for energy efficiency across US property markets. Using a panel of 48 metropolitan areas (MSAs) observed over the last 15 years, we model the geographic patterns and dynamics of building certification, relating industry composition, changes in economic conditions, characteristics of the local commercial property market, and the presence of human capital, to the cross-sectional variation in energy-efficient building technologies and the diffusion of those technologies over time. Understanding the determinants and the rate at which energy-efficient building practices diffuse is important for designing policies to affect resource consumption in the built environment.

Abstract:

This study addresses the challenges in ensuring energy efficiency and high indoor climate quality with efficient use of public money in the municipal building procurement process. Energy efficient municipal building procurement provides a significant leverage when steering the built environment towards the low-carbon economy targets of the EU. Municipal building department professionals need more skills and knowledge to appropriately define the requirements and identify the energy efficient design options accounting for the building’s changing operational environment. This study presents how to systematically integrate energy efficiency in the municipal procurement process of buildings by presenting the list of energy efficiency factors to be included into the procurement process. This list of factors clarifies how indoor climate quality, energy use, and the life cycle economy are related through technological solutions and how the optimal compromise solution can be determined. Furthermore, this list of factors explains the responsibilities in integrating energy efficiency within the municipal building procurement process. Applied in the design of the municipal building the list of factors contributes to more informed and transparent decision-making process.

Abstract:

IoT technology has great potential to transform the built environment and, in doing so, create energy savings. With operational energy use in buildings causing around 30 per cent of CO2 gas emissions, and demand for energy use in buildings on the rise, it is necessary to develop measures to reduce consumption, and IoT could hold the key to this. Just a few examples of ways that this can be achieved are: real-time energy monitoring, with IoT smart sensors measuring the power consumption of a building to show how and where energy is used; smart lighting, whereby unnecessary lighting is switched off and energy saved; and smart metering systems, leading to higher energy efficiency, cost savings and new data sources. Indeed, IoT devices in buildings can collect important data, which has a number of important applications, and the long-term value of IoT devices in buildings comes from mining the data collected by sensors and devices as this can be used to enhance building performance and efficiency. Professor Tomonari Yashiro, based at the Institute of Industrial Science, The University of Tokyo, is exploring how ICT and the IoT could help improve the sustainability and energy efficiency of buildings.

Full text

Abstract:

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.

Abstract:

Sustainable architecture encompasses more than energy efficiency, zero carbon dioxide (CO2) emission or renewable energy use in the built environment. It also needs to alleviate overall impacts on the natural environment or ecosystem that surrounds it. It may be argued that primitive vernacular architecture (architecture without architects) built and operated using local techniques and resources alone can be considered to be sustainable. Yet later, after the 1992 Rio Conference and its declarations, more specific definitions emerged putting weight on the rational use of land area, materials and energy, preferably local, as well as area efficient planning, economy and recyclability. The advantage of this is to reduce the ecological footprint of buildings and the climate gas emissions from a sector that represents 35–50 percent of global climate gas emissions, depending on how one counts. This paper clarifies concepts, questions cemented truths and points a way forward by asking; what’s next?

Abstract:

The development of new climate change policies has increased the motivation to reduce energy use in buildings, as reflected by a stringent regulatory landscape. The construction industry is expected to adopt new methods and strategies to address such requirements, focusing primarily on reducing energy demand, improving process efficiency and reducing carbon emissions. However, the realisation of these emerging requirements has been constrained by the highly fragmented nature of the industry, which is often portrayed as involving a culture of adversarial relationships and risk avoidance, which is exacerbated by a linear workflow. Recurring problems include low process efficiency, delays and construction waste. Building information modelling (BIM) provides a unique opportunity to enhance building energy efficiency (EE) and to open new pathways towards a more digitalised industry and society. BIM has the potential to reduce (a) waste and carbon emissions, (b) the endemic performance gap, (c) in-use energy and (d) the total lifecycle impact. BIM also targets to improve the whole supply chain related to the design, construction as well as the management and use of the facility. However, the construction workforce is required to upgrade their skills and competencies to satisfy new requirements for delivering BIM for EE. Currently, there is a real gap between the industry expectations for employees and current training and educational programmes. There is also a set of new requirements and expectations that the construction industry needs to identify and address in order to deliver more informed BIM for EE practices. This paper provides an in-depth analysis and gap identification pertaining to the skills and competencies involved in BIM training for EE. Consultations and interviews have been used as a method to collect requirements, and a portfolio of use cases have been created and analysed to better understand existing BIM practices and to determine current limitations and gaps in BIM training. The results show that BIM can contribute to the digitalisation of the construction industry in Europe with adapted BIM training and educational programmes to deliver more informed and adapted energy strategies.

Abstract:

The practice of urban planning and building design largely follow traditional methods while transforming the structure and quality of life in the built environment. The process of managing cities requires updates and integration of new technologies and research efforts. In this context, development of smart, sustainable, energy efficient, healthy, safe and secure built environment is a priority that is shaping modern cities all over the world. Though management of Indian cities tries to address these issues to a certain extent, it can be said that, as compared to many developed countries, aspects of safety and security have not been the top priority of our planners and designers. Research on Environmental Criminology and Environmental Psychology clearly indicates the important role and benefits of crime prevention through appropriate design of the built environment. In this context, this paper highlights the role of crime prevention strategies and the relevance of environmental criminology in current building practices for addressing security concerns in India.

Abstract:

Abstract Current research pays special attention to the application of approaches that promote sustainable design in a built environment and ensure energy efficiency. In this context, the form of housing buildings is an important parameter that has a meaningful impact on the use of energy in housing buildings. Hence, this research attempts to study the impact of the form of housing buildings on energy efficiency taking into account the mid-hot weather conditions in one of the middle-income housing buildings in new communities in Egypt. To achieve the research aim, a comparative analysis is carried out using parametric numerical analysis—DesignBuilder energy analysis—to compare the various hypothetical proposals for different building configurations. The study determines that the efficiency of energy use in buildings depends to a large extent on their forms that will help urban designers and planners to propose the best energy performance in the form of housing buildings in the stage of conceptual design suitable for other environmental, social and economic urban planning issues. These results should be incorporated into the building codes adopted in Egypt’s new cities in order to reach more energy-efficient housing buildings in Egypt.

Abstract:

In Europe, near zero energy buildings (NZEBs) represent the new frontier of energy efficiency in the built environment. Shifting the scale from NZEBs to net zero energy (NZE) settlements represents the opportunity to achieve further energy, environmental, and cost benefits, thanks to shared energy management, optimization of renewable energy systems, and microclimate mitigation. In particular, the last aspect takes advantage of the implementation of local microclimate mitigation strategies at a larger scale to improve settlements outdoor environmental conditions and citizens’ wellbeing. Furthermore, this inter-building scale mitigation involves relatively less severe working boundary conditions for buildings, able to both reduce building energy demand and improve HVAC (heating, ventilation, and air conditioning) system’s efficiency. In this study, this potential extra-energy saving, achievable without additional costs, is explored within the framework of a NZE settlement built in Italy thanks to an ongoing Horizon 2020 project. Improved working conditions for the operating air conditioning system and building energy savings thanks to settlement scale opportunities for microclimate mitigation are assessed. Findings show how this effect represents a further non-negligible energy-efficient and environmentally sustainable benefit achievable through the design and construction of NZE settlements. Potential energy savings are up to 24% when considering the double effect of microclimate mitigation.

Abstract:

Abstract The development and growing availability of modern technologies, along with more and more severe environment protection standards which frequently take a form of legal regulations, are the reason why attempts are made to find a quiet and economical propulsion system not only for newly built watercraft units, but also for modernised ones. Correct selection of the propulsion and supply system for a given vessel affects significantly not only the energy efficiency of the propulsions system but also the environment - as this selection is crucial for the noise and exhaust emission levels. The paper presents results of experimental examination of ship power demand performed on a historic passenger ship of 25 m in length. Two variants, referred to as serial and parallel hybrid propulsion systems, were examined with respect to the maximum length of the single-day route covered by the ship. The recorded power demands and environmental impact were compared with those characteristic for the already installed conventional propulsion system. Taking into account a high safety level expected to be ensured on a passenger ship, the serial hybrid system was based on two electric motors working in parallel and supplied from two separate sets of batteries. This solution ensures higher reliability, along with relatively high energy efficiency. The results of the performed examination have revealed that the serial propulsion system is the least harmful to the environment, but its investment cost is the highest. In this context, the optimum solution for the ship owner seems to be a parallel hybrid system of diesel-electric type

Abstract:

This paper focuses on the definition of a method supported by digital processes for a sustainable and user-orientated re-design of the existing building stock. Based on the analysis of the methodological and procedural aspects of the computational approach to architectural design in relation to different performance conditions, the research addresses the adoption of Building Information Modeling (BIM), intended as a powerful method for coordinating the complexity of the multiple, interdisciplinary and conflicting aspects involved in the rehabilitation of buildings. In addition to the advantages in terms of control and management, the BIM process has proven its effectiveness in tackling the issue of sustainability, allowing all actors involved in the research to share information and pro-actively control various outcomes of a building’s performance, such as energy and environmental quality. To show the opportunities and limitations of the digital management in information-based processes, the activities carried out in the framework of the European Horizon 2020 project “Pro-GET-onE—Proactive synergy of inteGrated Efficient Technologies on buildings’ Envelopes” are reported. The research, based on a case study method, which is applied to a student residence in Athens, demonstrates that BIM possesses great potentialities for developing effective and efficient construction and renovation processes toward buildings with high quality standards.

Abstract For further development of the dynamic exergy analysis within built environment the work proposes to take into account stochastic nature of variations of operational regimes. Using the probability theory and statistics methods, the set of parameters considered as relevant for uncertainty conditions are presented. It is shown that characteristics of buildings (insulation, window performance, heat recovery, etc.) and type of the heating system have undoubtedly a strong influence not only on the energy/exergy demand and consumption but also on the sensitivity of the energy/exergy parameters to variations of external conditions. According to the results obtained after implementations of energy efficient solutions coefficient of variation of energy/exergy-based parameters can be increased up to two times.

Abstract:

Introduction: High energy consumption by buildings is a great threat to the environment and one of the major causes of climate change. With a population of 1.4 billion people and one of the fastest-growing economies in the world, India is extremely vital for the future of global energy markets. The energy demand for construction activities continues to rise and it is responsible for over one-third of global final energy consumption. Currently, buildings in India account for 35% of total energy consumption and the value is growing by 8% annually. Around 11% of total energy consumption are attributed to the commercial sector. Energy-efficient retrofitting of the built environments created in recent decades is a pressing urban challenge. Presently, most energy-efficient retrofit projects focus mainly on the engineering aspects. In this paper, we evaluate various retrofitting options, such as passive architectural interventions, active technological interventions, or a combination of both, to create the optimum result for the selected building. Methods: Based on a literature study and case examples, we identified various energy-efficient retrofit measures, and then examined and evaluated those as applied to the case study of Awas Bhawan (Rajasthan Housing Board Headquarters), Jaipur, India. For the evaluation, we developed a simulation model using EQuest for each energy measure and calculated the resultant energy savings. Then, based on the cost of implementation and the cost of energy saved, we calculated the payback period. Finally, an optimum retrofit solution was formulated with account for the payback period and ease of installation. Results and discussion: The detailed analysis of various energy-efficient retrofit measures as applied to the case study indicates that the most feasible options for retrofit resulting in optimum energy savings with short payback periods include passive architecture measures and equipment upgrades.

Abstract:

Purpose – The purpose of this paper is to investigate the contribution of building management system (BMS) towards a sustainable built environment. Design/methodology/approach – The paper is based on the findings of a comprehensive literature survey, preliminary survey and a structured questionnaire survey. Quantitative data were analysed using a relative importance index. Content analysis was used for the qualitative data analysis. Findings – The results show that identifying user requirements, identifying BMS features, designing BMS, installation and commissioning, and operation and maintenance are the key steps in the BMS implementation process. High cost, lack of knowledge on BMS, unavailability of service and maintenance, and inadequate performance of BMS vendors were highlighted as barriers when adopting a BMS. Energy efficiency, reduction of operation and maintenance cost, occupant satisfaction, productivity, fault diagnosis, thermal comfort, indoor air quality, emergency response and level of controllability of building systems are some of the significant BMS functions that accomplish economic, environment and social sustainability pillars. Practical implications – This study increases the awareness on functionality of a BMS and its potential contribution towards a sustainable built environment. Originality/value – The study develops strong ties between BMS contribution and sustainability where built environment professionals could use the developed decision support model towards a sustainable built environment through the application of BMS.

Abstract:

Over the last years, existing technologies have been applied to agricultural environments, resulting in new precision agriculture systems. Some of the multiple profits of developing new agricultural technologies and applications include the cost reduction around the building and deployment of them, together with more energy-efficient consumption. Therefore, agricultural precision systems focus on developing better, easier, cheaper, and overall more efficient ways of handling agricultural monitoring and actuation. To achieve this vision, we use a set of technologies such as Wireless Sensor Networks, Sensors devices, Internet of Things, or data analysis. More specifically, in this study, we proposed a combination of all these technologies to design and develop a prototype of a precision agriculture system for medium and small agriculture plantations that highlights two major advantages: efficient energy management with self-charging capabilities and a low-cost policy. For the development of the project, several prototype nodes were built and deployed within a sensor network connected to the cloud as a self-powered system. The final target of this system is, therefore, to gather environment data, analyze it, and actuate by activating the watering installation. An analysis of the exposed agriculture monitoring system, in addition to results, is exposed in the paper.

Abstract:

INTRODUCTION A developer who had chronic asthma as a child built the first LEED® (Leadership in Energy and Environmental Design) Platinum certified apartment complex in Idaho. He has also heard from two residents that their asthma no longer resulted in attacks due to eliminating triggers in the interior environment. Eight years and a dozen multifamily affordable housing projects later, the LEED consultant on these projects has gathered insight on best practices, lessons learned and strategies that result in resident, owner and project team satisfaction. Ten projects have achieved LEED Platinum certification (two more are still under construction, but are on track for Platinum), and the HERS (Home Energy Rating System) scores are as low as 48. Feedback has been collected on what works, what doesn't and what matters most: from low energy bills to living in a healthy home and not having asthma attacks. These projects debunk the assumptions that energy efficiency adds too much cost or that green homes are only for the wealthy.

Abstract:

Building sector plays an important role in climate impacts mitigation, as it is responsible for 40% of global energy use and global GHG emissions. Climate change has a dual implication on the built environment: on one hand human settlements and buildings are vulnerable to the effects of changing climate and on the other hand the building sector has a significant climate change mitigation potential. Although nowadays the trends are positive, the share of newly built low-energy buildings is very low, the near-zero-energy building market is in its early phase. Simultaneously the optimizing technologies in the building design are strongly highlighted. The presence of the energy and environment efficient buildings and the stringent building energy regulations of the EU need more accurate building design. The constant design parameters will come to foreground and their role will be appreciated. The relevant sustainable development and building policies, as well as the building design, construction and maintenance should jointly respond both to adaptation to and mitigation of climate change. This paper focuses the relevance of the main constant design parameter: How to take into account the increasing outdoor temperature in the building energy design.

Abstract:

The internet of things (IoT) is a technology representing a rapidly ubiquitous development. The technologies supporting the IoT are becoming significant as it forms the basic need to analyze the environment and making it smarter. So far, the internet in context of IPs is considered as the largest network globally. The collection of data that includes the process of harvesting the monitored data is sensed by a huge number of participating sensors, which presents a challenging task due to its openly built technical issues resulting from typical limitations of WSNs (delivery time, energy, bandwidth) to the lack of standardized data collection of widespread WSN, required for practical deployment in both the upcoming and existing scenarios of IoT. This paper improves the above critical issue with optimizing the process of routing using the algorithm grey wolf optimization (GWO) which represents semantic form of optimization that typically reduces the drop, time delay, and energy.
