Available in PDF, EPUB and Kindle. Book excerpt: This research effort sought to achieve a solution package that yields energy savings greater than 30 percent over the pre-existing conditions in a minimally intrusive multifamily retrofit project. The Consortium for Advanced Residential Buildings (CARB) partnered with L+M Development Partners, Inc. on a Mitchell-Lama Housing Program project, Marcus Garvey Village, in Brooklyn, NY (Climate Zone 4A). The Mitchell-Lama Housing Program is a form of housing subsidy in the state of New York that provides affordable rental and cooperative housing to moderate- and middle-income families. Marcus Garvey Village was founded in 1975 and contains 625 residential units (ranging from studios to 5-bedroom units) in thirty-two 4-story garden-style apartment structures built with concrete and faced in light brown brick. The single largest challenge for implementation of energy conservation measures at Marcus Garvey was working within occupied spaces. Measures are being implemented in phases to minimize disruption. As of August 2015, the retrofit work is over 50 percent complete. The wall insulation, sealing of the through wall AC vent, and installation of new oil-filled electric baseboards with advanced controls are conducted at one time, limiting disruption to the living room space. In a similar fashion, the kitchen work is done, then the bathroom. The final selection of energy conservation measures is projected to save 26.5 percent in source energy with a cost just under $3.7 million and utility bill savings of nearly $480,000 (of an average $1.8 million annual utility cost for the development).

Book excerpt: Purpose of the Book In today's world, where sustainability and energy efficiency have become paramount, the significance of retrofitting and renovation has never been more relevant. This book, Revitalize and Renew: A Comprehensive Guide to Retrofit and Renovation Projects, is designed to be a definitive resource for anyone looking to breathe new life into existing structures. Whether you are a homeowner eager to modernize your living space, an architect aiming to balance aesthetics with functionality, or a contractor seeking to enhance your expertise, this book will guide you through the process of transforming old, outdated buildings into efficient, sustainable, and beautiful spaces. The primary purpose of this book is to equip you with the knowledge and tools necessary to make informed decisions about retrofit and renovation projects. It aims to demystify the processes involved, provide actionable steps, and inspire creativity in the pursuit of both functional and aesthetic improvements. By the end of this book, you will be well-prepared to embark on your own renovation journey, whether it involves minor updates or a complete overhaul. Scope of the Book Retrofit and renovation are often used interchangeably, yet they serve different purposes and involve distinct processes. This book clearly distinguishes between the two, while also showing how they can be complementary in creating modern, efficient buildings that respect their historical roots. Retrofit typically involves the addition of new technology or features to an existing building, with a strong focus on improving energy efficiency, safety, and resilience to environmental challenges. Examples include upgrading insulation, installing solar panels, or reinforcing structures against seismic activity. Renovation, on the other hand, focuses more on restoring or improving the physical aspects of a building—such as its structure, interiors, and exteriors—often for aesthetic purposes, modernization, or to repair damage. In this book, we will explore both concepts in depth, providing detailed guidance on a wide range of projects, from small-scale updates to large-scale transformations. The book is divided into several key sections: Foundations of Retrofitting and Renovation: A thorough exploration of the basics, including the differences between retrofitting and renovation, the initial assessments required, and how to plan and design a project that meets your goals. Key Retrofit and Renovation Projects: A hands-on guide to specific projects, including structural enhancements, energy efficiency improvements, electrical and plumbing upgrades, and both interior and exterior renovations. Sustainability and Future-Proofing: As environmental concerns grow, this section focuses on green retrofitting strategies, smart home technologies, and designing for health, wellness, and long-term sustainability. Case Studies and Practical Examples: Real-world examples and DIY project guides that provide inspiration and practical advice for various types of retrofit and renovation projects. Managing and Completing Your Project: A deep dive into project management, budgeting, financing, and post-renovation considerations to ensure that your project is successful from start to finish. The Growing Importance of Retrofitting and Renovation The modern built environment is facing unprecedented challenges, from climate change to aging infrastructure. Retrofitting and renovation offer solutions that not only enhance the functionality and safety of buildings but also contribute to environmental sustainability. Retrofitting, in particular, has gained momentum as a crucial strategy for reducing energy consumption and lowering carbon footprints, aligning with global efforts to combat climate change. Moreover, renovating existing buildings rather than constructing new ones can preserve historical and cultural values, reduce the demand for new materials, and minimize waste. As cities become more crowded and the need for housing and commercial space grows, the efficient use of existing structures through thoughtful renovation becomes increasingly important. Who Should Read This Book? This book is intended for a diverse audience: Homeowners who want to update their homes, improve energy efficiency, or increase property value.

Whether you are preserving the charm of a historic home, upgrading an outdated office building, or making your home more energy-efficient, Revitalize and Renew is here to support you every step of the way.

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.

Download or read book Energy and Water Efficiency in Multi Unit Residential Buildings written by Canada Mortgage and Housing Corporation. Policy and Research Division and published by Canada Mortgage and Housing Corporation. This book was released on 2002-01-01 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Implementing energy and water efficiency is a crucial consideration for today's property managers and building owners. Energy and water costs in multi-residential buildings can account for anywhere from 25% to 50% of total operating costs. While amendments to building codes and standards over the past 20 years have improved energy and water performance in newer buildings, over 50% of housing was constructed prior to 1980. Few of those have been upgraded to today's standards of energy efficiency. Improving energy and water efficiency can decrease operating costs, reduce maintenance fees, lower tenant turnover rates, increase the asset value of property, and extend the life of the building. CMHC, in partnership with the Ontario Ministry of Municipal Affairs and Housing (OMMAH), has developed a manual that details energy and water efficiency measures for existing multi-unit residential buildings. The document is based on a manual originally developed by the Ontario Ministry of Housing in the early 1980's. The new manual offers proven, current energy efficiency measures for the building envelope, mechanical, electrical, and domestic hot water heating systems. Both the User Guide and Technical Manual are designed to assist property managers in implementing an energy and water conservation program in mid- and high-rise residential buildings. They can be used to help organize activities, develop detailed energy and water conservation plans, and provide an understanding of which energy and water efficiency measures are best. The User Guide provides advice on how to manage activities, from conducting an energy/water preliminary assessment, determining appropriate conservation measures, estimating payback and the development of an energy/water plan. The Technical Manual outlines in detail more than 60 energy and water conservation measures for multi-unit buildings. Each provides basic details on assessing the viability of measures in relation to the specific requirements of buildings, as well as recommendations on integrating measures into ongoing maintenance, repair and/or renovation/retrofit work. Each measure can be used in isolation, in selected groupings, or integrated into any maintenance, repair and/or renovation/retrofit work on the building. Note: Individual energy and water efficiency measures have been placed on the CMHC high-rise website as the energy and water efficiency "Tip of the Week". The manual will form a part of the reference material for a series of energy management seminars being organized by the Ontario Non-Profit Housing Association in the spring of 2004.

Download or read book Predicted Versus Actual Savings for a Low rise Multifamily Retrofit in Boulder Colorado written by L. Arena and published by . This book was released on 2013 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: To determine the most cost-effective methods of improving buildings, accurate analysis and prediction of the energy use of existing buildings is essential. However, multiple studies confirm that analysis methods tend to over-predict energy use in poorly insulated, leaky homes and thus, the savings associated with improving those homes. In NREL's report titled 'Assessing and Improving the Accuracy of Energy Analysis of Residential Buildings,' researchers propose a method for improving the accuracy of residential energy analysis methods. A key step in this process involves the comparisons of predicted versus metered energy use and savings. In support of this research need, CARB evaluated the retrofit of a multifamily building in Boulder, CO. The updated property is a 37 unit, 2 story apartment complex built in 1950, which underwent renovations in early 2009 to bring it into compliance with Boulder, CO's SmartRegs ordinance. Goals of the study were to: 1) evaluate predicted versus actual savings due to the improvements, 2) identify areas where the modeling assumptions may need to be changed, and 3) determine common changes made by renters that would negatively impact energy savings. In this study, CARB seeks to improve the accuracy of modeling software while assessing retrofit measures to specifically determine which are most effective for large multifamily complexes in the cold climate region. Other issues that were investigated include the effects of improving building efficiency on tenant comfort, the impact on tenant turnover rates, and the potential market barriers for this type of community scale project.

Available in PDF, EPUB and Kindle. Book excerpt: The complete resource on performing sustainable renovations for both Historic and modern existing buildings This forward-looking and insightful guide explores how the sustainable renovation of existing buildings presents great opportunities for initiating extensive changes in the performance of the built environment. Great examples of existing building upgrades are examined, illustrating how to do sustainable renovations, along with current design approaches for radically improving the functionality of existing prewar, postwar, and late modern buildings. Sustainable Renovation saves its key focus for institutional and commercial buildings, but discusses the challenges they pose within a global scope that encompasses all building practices. Some of the discussions in this book include: The significance of energy and resource demands by the building sector and the urgency of reducing loads in existing buildings Management, design, and construction approaches to achieve major modernization in occupied buildings International case studies that focus on methods and benefits of successful sustainable transformations of existing building performance Repurposing buildings to preserve style and add performance remains a work in progress as designers and builders discover new methods for improving sustainable practices and standards. With incremental modernization and operations strategies available for immediate implementation, this book demonstrates the different ways of thinking necessary when considering and attempting the integration of sustainable concepts into existing buildings—and enables readers to rethink the world that's built around them.

This book was released on 2019-03-18 with total page 164 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.
