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 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 The Handbook of Sustainable Refurbishment written by Nick V. Baker and published by Earthscan. This book was released on 2009 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The refurbishment of existing buildings is a neglected subject within sustainable architecture; attention is usually focused on new buildings. Old buildings can use large amounts of energy and provide poor internal conditions for occupants. They may have high heating demand, poor lighting, poor ventilation, solar penetration and glare, and poor control of heating and cooling. Demolition is an option but the alternative of refurbishment is starting to be seen as more sustainable in terms of architectural value, materials use, neighborhood disruption and waste disposal. Building new is more carbon intensive and carries many wider environmental impacts. In addition, the potential impact of low energy refurbishment is much greater than that for new build since there are many more existing buildings than will be built in the next 10 - 20 years, the period over which many CO2 emission targets apply.
Download or read book Integrative Approach to Comprehensive Building Renovations written by Vesna Žegarac Leskovar and published by Springer. This book was released on 2019-03-18 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new approach to building renovation, combining aspects of various professional disciplines, integrating green building design, structural stability, and energy efficiency. It draws attention to several often-overlooked qualities of buildings that should be comprehensively integrated into the context of building renovation. The book presents an overview of the most important renovation approaches according to their scope, intensity, and priorities. Combining basic theoretical knowledge and the authors’ scientific research it emphasizes the importance of simultaneous consideration of energy efficiency and structural stability in building renovation processes. It simultaneously analyses the effects of various renovation steps related to the required level of energy efficiency, while it also proposes the options of building extension with timber-glass upgrade modules as the solution to a shortage of usable floor areas occurring in large cities. This book offers building designers and decision makers a tool for predicting energy savings in building renovation processes and provides useful guidelines for architects, city developers and students studying architecture and civil engineering. Additionally, it demonstrates how specific innovations, e.g., building extensions with timber-glass modules, can assist building industry companies in the planning and development of their future production. The main aim of the current book is to expose various approaches to the renovation of existing buildings and to combine practical experience with existing research, in order to disseminate knowledge and raise awareness on the importance of integrative and interdisciplinary solutions.

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 Energy renovation of multi family buildings in Sweden written by Lina La Fleur and published by Linköping University Electronic Press. This book was released on 2019-09-18 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residential buildings account for 27% of the final energy use in the European Union. In cold climates, space heating represents the largest proportion of the energy demand in residential buildings. By implementing energy efficiency measures (EEMs) in existing buildings, energy use can be significantly reduced. The Energy Performance of Buildings Directive states that renovations of buildings offer an opportunity to improve energy efficiency. Renovations that include measures implemented with the specific purpose of reducing energy use are referred to as energy renovations. In addition to improving energy efficiency, an energy renovation can also improve the indoor environment. Sweden, like many other European countries, faces the challenge of renovating an ageing building stock with poor energy performance. Improving energy efficiency and performing energy renovations in a cost-effective manner is central, and optimization approaches are often used to identify suitable EEMs and energy renovation approaches. New buildings usually feature better energy performance compared to older buildings, and one approach for reducing energy use in the building sector could be to demolish old buildings with poor thermal performance and build new buildings with better thermal performance. The aim of this thesis is to evaluate energy renovations of multi-family buildings with regard to space heating demand, life cycle costs, indoor environment and primary energy use. The choice between energy renovation of a multi-family building and the demolition and construction of a new one is also investigated with regard to life cycle costs (LCCs). A Swedish multi-family building in which energy renovation has been carried out is used as a case study. The building was originally constructed in 1961 and has a lightweight concrete construction. The renovation included improving the thermal performance of the building envelope and replacing the exhaust air ventilation system with a mechanical supply and exhaust air ventilation system with heat recovery. The methods used in the studies include dynamic whole building energy simulation, life cycle cost analysis and optimizations, and a questionnaire on indoor environment perception. Extensive field measurements have been performed in the building prior to and after renovation to provide input data and to validate numerical predictions. In addition to the studied building, the analysis of the choice between energy renovation and the demolition and construction of a new building includes three other building construction types, representing common Swedish building types from the 1940s, 1950s and 1970s. The analysis shows that the energy renovation led to a 44% reduction in space heating demand and an improved indoor environment. The indoor temperature was higher after the renovation and the perception of the indoor temperature, air quality and noise in the building improved. The EEMs implemented as part of the energy renovation have a slightly higher LCC than the optimal combinations of EEMs identified in the LCC optimization. It is not cost-optimal to implement any EEMs in the building if the lowest possible LCC is the objective function. Attic insulation has a low cost of implementation but has limited potential in the studied building with its relatively good thermal properties. Insulation of the façade is an expensive measure, but has a great potential to reduce heat demand because of the large façade area. Façade insulation is thus required to achieve significant energy savings. Heat recovery in the ventilation system is cost-effective with an energy saving target above 40% in the studied building. The primary energy factors in the Swedish Building Code favor ground source heat pumps as a heat supply system in the studied building. The LCC of renovation is lower compared to demolishing and constructing a new building. A large proportion of the LCC of demolition and new construction relates to the demolition of the existing building. In a building with a high internal volume to floor area ratio, it is not always possible to renovate to the same energy performance level as when constructing a new building. A more ambitious renovation approach is also needed compared to a building with a smaller volume to floor area ratio. Nära 27 % av den totala energianvändningen i den Europeiska Unionen sker i bostäder. I länder med kallt klimat används den största delen till uppvärmning. Genom att implementera energieffektiviseringsåtgärder i befintliga byggnaden kan energiprestandan signifikant förbättras. Europeiska Unionens direktiv om byggnaders energiprestanda framhåller att ett tillfälle att förbättra byggnaders energieffektivitet finns då byggnader ska renoveras. Byggnadsrenoveringar som innehåller åtgärder som implementeras med det primära syftet att minska energianvändningen kallas ofta energirenoveringar. Utöver energieffektivisering kan energirenoveringar ofta förbättra inomhusmiljön i byggnaden. Som många andra Europeiska länder står Sverige inför utmaningen att renovera ett åldrande byggnadsbestånd med låg energiprestanda. Kostnadseffektivitet är centralt vid energirenoveringar och energieffektivisering och optimeringsansatser är vanliga för att identifiera vilka energieffektiviseringsåtgärder som bör implementeras. Nya byggnader har som regel bättre energiprestanda jämfört med äldre byggnader, och en ansats till ett minska energianvändningen i byggnadssektorn överlag är således att riva äldre byggnader med låg energiprestanda och konstruera nya byggnader med bättre energiprestanda. Syftet med denna avhandling är att utvärdera energirenoveringar av flerfamiljshus avseende effekterna på uppvärmningsbehov, livscykelkostnader, inomhusmiljö och primärenergianvändning. Valet mellan energirenovering kontra att riva och bygga en ny byggnad analyseras också utifrån ett livscykelkostnadsperspektiv. För att studera detta har en svensk flerfamiljsbyggnad som genomgått energirenovering studerats. Byggnaden konstruerades 1961 och har en lättbetongstomme. När byggnaden renoverades förbättrades prestandan hos byggnadens klimatskal och frånluftsventilationssystemet byttes ut mot ett balanserat mekanisk ventilationssystem med värmeåtervinning. Metoderna som använts i studierna i denna avhandling är dynamisk byggandssimulering, beräkning och optimering av livscykelkostnader, samt en enkätstudie om hur de boende uppfattar sin inomhusmiljö. Omfattande mätningar har utförts i byggnaden och har använts som indata och för att validera resultaten. Utöver den studerade byggnaden har tre andra byggnadstyper inkluderats i analysen av valet mellan energirenovering och att riva och konstruera en ny byggnads. Dessa byggnadstyper representerar vanliga svenska byggnadstyper från 1940-, 1950- och 1970-talet. Analyserna visar att den renovering som genomfördes i byggnaden ledde till en minskning av uppvärmningsbehovet med 44 % och en förbättring av inomhusmiljön. Inomhustemperaturen var högre efter renoveringen, och de boende uppfattade temperaturförhållanden, luftkvalitet och bullersituationen som bättre efter renoveringen. De energieffektiviserande åtgärder som implementerades vid renoveringen gav en något högre livscykelkostnad än de åtgärder som identifierades som optimala genom livscykelkostnadsoptimering. Det är inte kostnadseffektivt att implementera några energieffektiviseringsåtgärder som del av renoveringen om den lägsta livscykelkostnaden är målsättningen. Vindsisolering är en förhållandevis billigt åtgärd att genomföra, men har begränsad potential i den studerade byggnaden vars vind redan har relativt god termisk prestanda. Fasadisolering kräver en större investering, men har större potential att minska energianvändning på grund av den stora fasadytan. Detta innebär att det är nödvändigt att isolera fasaden för att uppnå hög energibesparing. Värmeåtervinning i ventilationssystemet är kostnadsoptimalt om ett energisbesparingsmål på mer än 40 % ställs på energirenoveringen. Primärenergifaktorerna i den svenska byggnadskoden gynnar bergvärmepump som energitillförselsystem i de studerade byggnaden. Kostnaden för att energirenovera är lägre än att riva och bygga en ny byggnad. En stor andel av kostnaderna vid rivning och nybyggnation är kopplad till rivning och bortforsling av rivningsmassa. I byggnadstyper med stor inre volym i förhållande till uppvärmd golvyta är det inte alltid möjlig att energirenovera till en energiprestanda som är lika god som en ny byggnad. Det krävs också en mer ambitiös renovering för att uppnå samma energiprestanda som en byggnad med mindre inre volym i förhållande till uppvärmd golvyta.

Available in PDF, EPUB and Kindle. Book excerpt: With little or relatively modest investment, schools being refurbished or undergoing maintenance can make disproportionately large gains in energy efficiency that can also result in large financial savings. This document offers guidance on the selection of appropriate measures that can improve a facility's energy efficiency, depending on the type of building, method of construction, and physical condition of the facility. It provides technical descriptions of the most commonly used measures, followed by examples of a combination of measures as applied to older, heavily constructed buildings and more recently built schools. It describes proven energy efficiency measures undertaken during school refurbishment along with case studies that illustrate the effectiveness of these measures. The case studies include details on economic performance together with descriptions of other benefits not readily expressed in monetary terms, such as improved comfort. Appendices present a description of the measures of economic performance and definition of financial terms, and discuss the creation of "user manuals" by the design team that can guide users in the physical operations of the building and its maintenance. A glossary is provided. (Contains 58 references.) (GR)

This book was released on 2017-01-03 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost-Effective Energy Efficient Building Retrofitting:Materials, Technologies, Optimization and Case Studies provides essential knowledge for civil engineers, architects, and other professionals working in the field of cost-effective energy efficient building retrofitting. The building sector is responsible for high energy consumption and its global demand is expected to grow as each day there are approximately 200,000 new inhabitants on planet Earth. The majority of electric energy will continue to be generated from the combustion of fossil fuels releasing not only carbon dioxide, but also methane and nitrous oxide. Energy efficiency measures are therefore crucial to reduce greenhouse gas emissions of the building sector. Energy efficient building retrofitting needs to not only be technically feasible, but also economically viable. New building materials and advanced technologies already exist, but the knowledge to integrate all active components is still scarce and far from being widespread among building industry stakeholders. Emphasizes cost-effective methods for the refurbishment of existing buildings, presenting state-of-the-art technologies Includes detailed case studies that explain various methods and Net Zero Energy Explains optimal analysis and prioritization of cost effective strategies
Download or read book Facade Refurbishment Toolbox written by Thaleia Konstantinou and published by TU Delft. This book was released on 2014-09-05 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The starting point of the research is the need to refurbish existing residential building stock, in order to reduce its energy demand, which accounts for over one fourth of the energy consumption in the European Union. Refurbishment is a necessary step to reach the ambitious energy and decarbonisation targets for 2020 and 2050 that require an eventual reduction up to 90% in CO2 emissions. In this context, the rate and depth of refurbishment need to grow. The number of building to be renovated every year should increase, while the energy savings in renovated buildings should be over 60% reduction to current energy demand. To achieve that, not only is it necessary to find politics and incentives, but also to enable the building industry to design and construct effective refurbishment strategies. This research focuses on refurbishment of the building envelope, as it is very influential with regard to energy reduction.
Download or read book Sustainable Refurbishment written by Sunil Shah and published by John Wiley & Sons. This book was released on 2012-07-16 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Refurbishment Governments across the EU and developed countries are increasingly being directed towards improving existing built stock as a key ingredient to meeting climate change challenges. This guide to green ‘retro-fitting’ for corporate real estate, facility managers and occupiers struggling to reduce their building’s carbon footprint will help in the planning and management of a sustainable refurbishment programme. Sustainable Refurbishment is structured into four parts: the first gives the context, together with an overview on sustainable development and refurbishment projects separately, and the value gained from a sustainable refurbishment. Part Two details the regulatory and financial drivers, together with market pressures, and provides an overview of where this is leading, giving the implications for sustainable refurbishment. Part Three provides technical support on carbon measures, helping to determine the feasibility of good practices as part of the refurbishment. Included is a review of energy efficiency, renewable and low carbon technologies and embodied carbon to enable lifecycle carbon calculations, together with the necessary behavioural change aspects needed to embed the changes. Linkages and benefits between the technologies will be highlighted. Part Four reviews refurbishment from a wider environmental perspective, understanding the challenges and opportunities that exist for particular developments from a materials, water, biodiversity and transport perspective. Throughout the book, checklists are provided on typical activities and best practice; these are expanded through relevant case studies and examples to show-case previous good practices and lessons learnt. The book’s structure allows a matrix approach, with Parts Three and Four containing the technical information necessary to deliver sustainable refurbishment. The book provides a much-needed link between policy-level commitment and detailed technical delivery. This easily digestible and authoritative review of the key issues in green retro-fitting is crucial for facilities managers; building surveyors; property managers/owners; and corporate real estate involved in sustainable refurbishment by offering the practical support needed to make it happen.
