This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The retrofit of buildings to improve energy performance represents a vast opportunity in the construction market with the potential to create jobs, reduce energy demand, and achieve environmental benefits. Multiple challenges need to be overcome to unleash this potential and realize the benefits of investments in improving building energy performance. While large facilities often have easily predictable energy saving potential at scales that are attractive to the financial industry, they are often pursued in a manner that achieves only low hanging fruit for short term economic return. As a consequence, they often fall short of their potential to be pursued as a long term solution. Small sized buildings face even more challenges often related to the lack of the owners abilities to manage and finance energy efficiency improvements. The goal of this research is to develop a framework that supports the continuous improvement of processes involved in developing energy retrofit projects for small sized commercial buildings. The concept of regenerative thinking guided the investigation of value creation and exchange in networks of the stakeholders of a given energy retrofit. Characterization of investment risk in the value adding processes enables more informed investment decisions required to bring a retrofit project to optimal fruition. This enables the identification of high-risk investments during the process that can be elevated as key decisions to prove the investment risks are proportionate to the value being offered. The reduction of project development costs and risks can then contribute to a market-driven expansion of these project and the resulting economic, ecological, and social system effects. In addition, process improvement interventions can be designed and evaluated by their potential and actual effects in lowering the capital investment required to pursue retrofit projects. Key elements of this framework are developed through case studies, focus groups, and interviews. In conclusion, research results examining the value of the framework in improving the business development process for small commercial building energy retrofit projects are presented.
Download or read book The Mass Retrofitting of an Energy Efficient Low Carbon Zone written by Mark Deakin and published by Springer. This book was released on 2014-12-29 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maximizing reader insights into the strategic value of mass retrofits in the residential property sector through a detailed case study analysis of the ‘Hackbridge project’, this book uses this development to broaden understanding of how planners may perform urban regeneration in accordance with a centralized plan. This book demonstrates how urban morphology matters, not only with respect to either the geometry of design and construction systems, or occupational behaviours, but with regards to the potential with which the planning, (re)development, design, construction, use and occupation of buildings, has to not only lower levels of energy consumption and rates of carbon emission, but also to reduce global warming associated with climate change. Delivering a critique of the state-of-the-art on urban morphology, the geometry of design typologies, construction systems and occupational behaviours and armed with the critical insights this offers, this book offers a context-specific analysis of how institutions can begin to actively plan for, integrate and sustain the development of energy efficient-low carbon zones.

Download or read book Deep Energy Retrofit Guide for Public Buildings written by Rüdiger Lohse and published by Springer. This book was released on 2019-04-10 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides detailed information on how to set up Deep Energy Retrofits (DERs) in public buildings, and shares in-depth insights into the current status of the major technologies, strategies and practical best practice examples of how to cost-effectively combine them. Case studies from Europe are analyzed with respect to energy use before and after renovation, reasons for undertaking the renovation, co-benefits achieved, resulting cost-effectiveness, and the business models employed. The building sector holds the potential for tremendous improvements in terms of energy efficiency and reducing carbon emissions, and energy retrofits to the existing building stock represent a significant opportunity in the transition to a low-carbon future. Moreover, investing in highly efficient building materials and systems can replace long-term energy imports, contribute to cost cutting, and create a wealth of new jobs. Yet, while the technologies needed in order to improve energy efficiency are readily available, significant progress has not yet been made, and “best practices” for implementing building technologies and renewable energy sources are still relegated to small “niche” applications. Offering essential information on Deep Energy Retrofits, the book offers a valuable asset for architects, public authorities, project developers, and engineers alike.
Download or read book Deep Energy Retrofit A Guide for Decision Makers written by Alexander Zhivov and published by Springer Nature. This book was released on 2021-02-10 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many governments worldwide are setting more stringent targets for reductions in energy use in government/public buildings. Buildings constructed more than 10 years ago account for a major share of energy used by the building stock. However, the funding and “know-how” (applied knowledge) available for owner-directed energy retrofit projects has not kept pace with new requirements. With typical retrofit projects, reduction of energy use varies between 10 and 20%, while actual executed renovation projects show that energy use reduction can exceed 50%, and can cost-effectively achieve the Passive House standard or even approach net zero-energy status (EBC Annex 61 2017a, Hermelink and Müller 2010; NBI 2014; RICS 2013; Shonder and Nasseri 2015; Miller and Higgins 2015; Emmerich et al. 2011). Building energy efficiency (EE) ranks first in approaches with resource efficiency potential with a total resource benefit of approximately $700 billion until 2030. EE is by far the cheapest way to cut CO2 emissions (McKinsey 2011, IPCC 2007). However, according to an IEA study (IEA 2014a), more than 80% of savings potential in building sector remains untapped. Thus, the share of deployed EE in the building sector is lower than in the Industry, Transport, and Energy generation sectors. Estimates for the deep renovation potentials show: €600-900bn investment potential, €1000-1300bn savings potential, 70% energy-saving potential, and 90% CO2 reduction potential.

Download or read book Retrofitting the Built Environment written by William Swan and published by John Wiley & Sons. This book was released on 2013-08-06 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physical upgrading of the existing domestic and industrial building stock to improve energy performance is an essential part of a transition to a low carbon society. Successfully retrofitting buildings to improve energy performance is not simply a technological challenge, it is a complex socio-technical problem that needs to be addressed in a co-ordinated way, utilising skills and knowledge from a range of industrial and academic backgrounds. Within both the academic and practitioner communities there is a growing understanding of the scale and nature of the problem, one which encompasses issues such as policy and regulation, people and behaviour, supply chain and process, as well as issues of technology. Retrofitting the Built Environment discusses the factors that impact on the retrofit problem, providing a clear analysis of the main issues that the academic and industrial communities must engage with to resolve the problems of domestic energy and retrofit. The book is divided into four broad sections: Understanding the Problem Policy and Regulation Implementing and Evaluating Retrofit People and Communities Academic and industrial researchers, policy makers and industry practitioners will find each section covers a mix of policy, technical and social science issues, presented by both academic and industry authors, giving a wide and detailed perspective of the issue. The Editors Will Swan is a Senior Lecturer in Buildings Retrofit in the School of the Built Environment at the University of Salford.

Book excerpt: The recast of the Energy Performance of Buildings Directive (EPBD) was adopted by the European Parliament and the Council of the European Union on 19 May 2010. For new buildings, the recast fixes 2020 as the deadline for all new buildings to be “nearly zero energy” (and even sooner for public buildings – by the end of 2018). This book gives practitioner an important tool to tackle the challenges of building refurbishment towards nearly zero energy. This book is welcome at this time and sets the scene for professionals whether practitioners or researchers to learn more about how we can make whether old or new buildings more efficient and effective in terms of energy performance.
Download or read book Building Renovation written by Manuela Grecchi and published by Springer Nature. This book was released on 2022-01-01 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the building renovation process by systematizing the phases of analysis and prior knowledge through a project that not only considers energy savings but also thoroughly examines complex issues, such as defining the correct new functions and answers to new needs. The urgency of climate change and the many problems associated with the excessive use of energy are forcing a reorganization of the renovation process with an interest in reusing existing buildings with a more sustainable approach. The adaptive transformation of old buildings has become a dominant theme in many urban renewal projects. It must necessarily include strategies for energy efficiency, reduced pollutant emissions, improved environmental performance, economic sustainability and cultural identity. The examples selected are intended to provide evidence of good practices in the review and transformation of old buildings.
Download or read book Construction for a Regenerative Future written by Urban Persson and published by Taylor & Francis. This book was released on 2022-12-09 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a book about how to manage the processes involved in a construction project towards a sustainable and regenerative endproduct. It covers key project management concepts and links the construction process to the objectives of UN SDGs and beyond zero carbon emissions throughout the whole project life cycle. This introductory textbook is written from a project manager's perspective including considerations of circular economy throughout the construction process focusing on a regenerative or restorative outcome. The book examines the importance of the type and purpose of a building, circularity and de-construction, the site, the client and its organisation, stakeholder considerations, the project organisation, the procurement of consultants and contractors, project performance during design and construction, project hand-over to the client, and the building's operation and maintenance. It also illustrates how to verify the building using existing environmental certifications, how to calculate carbon emissions, and how to deal with used construction materials from a circular economy perspective. International examples of best practice are included throughout, and the book is structured in a way which students will find engaging and easy to follow. This is an ideal textbook for use on construction, architecture, and engineering programmes where the emphasis must urgently be placed on students fostering regenerative construction solutions in their coming professional life.
Download or read book Deep Energy Retrofit written by Alexander Zhivov and published by Springer Nature. This book was released on 2020-07-13 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides detailed information on how to set up Deep Energy Retrofits (DERs) in public buildings, and shares in-depth insights into the current status of the major technologies, strategies and best practice examples of how to cost-effectively combine them. Case studies from the U.S.A. and Europe show that that Deep Energy Retrofit can be achieved with a limited core technologies bundle readily available on the market. Characteristics of some of these core technology measures depend on the technologies available on an individual nation’s market, on the minimum requirements of national standards, and on economics (as determined by a life cycle cost analysis). Also, requirements to building envelope-related technologies (e.g., insulation levels, windows, vapor and water barriers, and requirements for building airtightness) depend on specific climate conditions. This Guide provides best practice examples of how to apply these technologies in different construction situations. High levels of energy use reduction using core technology bundles along with improvements in indoor climate and thermal comfort can be only achieved when a Deep Energy Retrofit adopts a quality assurance process. In addition to design, construction, commissioning, and post-occupancy phases of the quality assurance process, the Guide emphasizes the importance of clearly and concisely formulating and documenting the Owner’s goals, expectations, and requirements for the renovated building during development of the statement of work. Another important component of the quality assurance process is a procurement phase, during which bidders’ qualifications, their understanding of the scope of work and its requirements, and their previous experience are analyzed. The building sector holds the potential for tremendous improvements in terms of energy efficiency and reducing carbon emissions, and energy retrofits to the existing building stock represent a significant opportunity in the transition to a low-carbon future. Moreover, investing in highly efficient building materials and systems can replace long-term energy imports, contribute to cost cutting, and create a wealth of new jobs. Yet, while the technologies needed in order to improve energy efficiency are readily available, significant progress has not yet been made, and “best practices” for implementing building technologies and renewable energy sources are still relegated to small “niche” applications.

Download or read book Retrofit for Purpose written by Greg Penoyre and published by Routledge. This book was released on 2019-07-25 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Retrofit for Purpose examines a range of state-of-the-art non-domestic retrofit projects. Its chapters explore common challenges, offer practical solutions and provide a clarion-call to architects and clients for better, smarter retrofit. Twelve case studies focus as much on the transformation of usability and image as on the improvements in the energy and resource use of non-domestic buildings. While an essay section places these projects into a wider context, suggesting that despite the importance of sharing and analysing data, there is more to retrofit than just energy efficiency. The authors take a range of other retrofit variables: from client ambition to tenure, budget, use type, age, context, fashion and fiscal arrangements and assess how retrofit can be made affordable, how it fits in with wider government policy and how performance can be measured.

Available in PDF, EPUB and Kindle. Book excerpt: The evolution of sustainability, with a practical framework for integration Regenerative Development and Design takes sustainability to the next level, and provides a framework for incorporating regenerative design principles into your current process. The Regenesis Group is a coalition of experienced design, land-use, planning, business, and development professionals who represent the forefront of the movement; in this book, they explain what regenerative development is, how and why it works, and how you can incorporate the fundamental principles into your practice. A clear, focused framework shows you how to merge regenerative concepts with your existing work, backed by numerous examples that guide practical application while illustrating regenerative design and development in action. As the most comprehensive and systemic approach to regenerative development, this book is a must-have resource for architects, planners, and designers seeking the next step in sustainability. Regenerative design and development positions humans as co-creative and mutually-evolving participants in an ecosystem—not just a built environment. This book describes how to bring that focus to your design from the earliest stages. Understand the fundamentals of regenerative design and development Learn how regenerative development contributes to sustainability Integrate regenerative development concepts into practice Examine sample designs that embody the regenerative concept To create a design with true sustainability, considerations must extend far beyond siting, materials, and efficiency. Designers must look at the place, it's inhabitants, and the purpose—the whole living ecosystem—and proceed with their work from that more humbling perspective. The finished product should itself be an ecosystem and sustainable economy, which is the root of the regenerative development approach. Sustainability has evolved, and the designer's responsibility has increased in kind. Regenerative Development and Design provides an authoritative resource for those ready to take the next step forward.

Download or read book Build New Or Retrofit Leverage Cost Benefits for Building Energy Efficiency written by Dong Zhao and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Buildings consume huge energy and omit large CO2 emissions. Green buildings adopt advanced building technologies and largely reduce energy consumption. A barrier to wide green building development is the high costs that include hard costs for materials, construction, and mechanical, electrical, and plumbing systems and soft costs for design services, financing, overhead, insurance, taxes, and fees. Except for new construction projects, retrofit projects also produce green buildings through remodeling, renovation, and redevelopment of existing buildings or properties. Most extant studies focus on the cost analysis of green buildings and non-green buildings; however, there is a lack of evidence about the cost benefits in comparing new and retrofit projects. The objective of this study is to provide empirical evidence for the cost decomposition of new and retrofit projects and analyze the cost benefits between them. This study collects the data on energy use, building technology, and costs from 235 certified green homes in the United States and evaluates the cost benefits. Results show that the average cost of energy retrofit projects is $118.0/ft2 ($1,270.5/m2) in the 2021 U.S. dollar value, 30% less than new projects. The major element of the costs is land acquisition and development, which accounts for 35% of the retrofit costs and six times greater than new projects. When excluding the land costs, the average cost drops to 68.2/ft2 ($733.88/m2), 49% less than new projects. Retrofit projects use similar building technologies as new projects and produce larger energy savings. The findings demonstrate that the cost-benefit values generated by retrofit projects are 86% greater than new projects considering the land costs and 142% greater without considering the land costs. This study contributes to the cost management for complex building projects and energy policy for sustainable developments, suggesting a great potential of energy retrofit to overcome the barrier of high costs in promoting the green building movement as well as implications for public policies such as effective subsidy programs.
Download or read book Energy Design Strategies for Retrofitting written by A. Boeri and published by WIT Press. This book was released on 2014-12-15 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a coherent and realistic vision of the implications of the energy issue in the future development of our cities; places emphasis on the links between very specific and technical topics and the most challenging issues concerning energy savings and the transition to a low carbon society. A great part of the built environment in most European cities consists of buildings dating from 60s to early 90s, for residential purposes: this stock clearly presents several problems related to its functional layout, as well as its energy/thermal behaviour. Applying sustainable and energy savings principles to retrofitting interventions on the stock above is one of the most urgent challenges to be met in the very near future. Giving some examples and case studies, this book investigates retrofitting interventions in terms of energy balance: from design strategies to choice of materials and components; from market trends analysis to economical assessment, from the targeted energy performance to the energy investments needed for achieving it. The reader will benefit from the real life experiences and related results described in this book and acquire all the tools for a constructive evaluation of the different options available to him/her, when faced with retrofitting interventions, thanks to a global view of all the issues involved.
Download or read book Developing the Construction Phase of the Integrated Building Lifecycle Process Model for Retrofit Projects written by Ruo Gao and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of increased concern about energy shortage and consumption in the world, it becomes natural to look towards the building industry to seek critical improvements to achieve energy efficiency. Advanced Energy Retrofit (AER) projects can significantly reduce energy consumption in buildings. The construction process can significantly influence the success of AER projects. It is important for a team to have a clearly defined process for delivering the construction, as a part of an integrated process, and understand information flows between the activities within the process. A challenge to the successful implementation of an integrated construction process which involves many disciplines is to deliver a smooth information flow in the process with an emphasis of integrated attributes. To address this problem, this research is focused on the development of a process model for the construction phase of an energy retrofit building project. The process investigates construction activities at a building system level in an integrated fashion for the AER projects, which are beneficial to researchers and practitioners who are interested in studying the integrated construction process. The final process model contains key activities in the retrofit project construction process that can be implemented in the integrated approach. The model was developed and validated through literature analysis, interviews, and focus group discussions.The developed model is one phase of the Integrated Building Lifecycle Process Map (IBLPM), which is focused on the development of the activities that occur throughout the entire lifecycle process for delivering an energy retrofit project. The construction phase of the IBLPM can serve as a reference for project teams to collaboratively identify the key construction activities which are shown in a logical sequence and at a system level. Therefore, it allows people to clearly define the content of the construction process and help project team to make the right decision at the right time. In addition, the process model organizes the activities into an integrated construction framework, which will facilitate the collaboration of the various project participants.
