This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The McKinsey Global Initiative identified existing building retrofits as an integral component to achieve a 75% reduction in greenhouse gas emissions in the United Sates by 2050 (Fluhrer, Maurer, & Deshmukh 2010). However, this will require energy efficiency retrofits for existing buildings to be deployed more frequently and achieve higher energy savings on average. Deep Energy Retrofits using the Integrative Design Process can result in 30-60%+ energy savings in office buildings. Because Deep Energy Retrofits require higher upfront capital costs, in an economy still recovering from the economic downturn, financial decision makers may not be inclined to invest more capital solely on the basis of higher energy savings. In this paper, Deep Energy Retrofit case studies, research papers, and retrofit guides were examined to answer the question: are deep energy retrofits financially viable, and if so, under what conditions. Utility cost savings, avoided capital costs, as well as additional benefits, like increased reputation, environmental health and enhanced comfort of the building are ways in which Deep Energy Retrofits can be cost-effective; and in some cases profitable for the financial decision maker or building owner. Deep Energy Retrofits using the integrative Design Process present a low-cost and effective strategy to reduce GHG emissions and help aid the US in climate stabilization efforts.

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. Offering essential information on Deep Energy Retrofits, the book offers a valuable asset for architects, public authorities, project developers, and engineers alike.

This book was released on 2010-06-10 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: America's economy and lifestyles have been shaped by the low prices and availability of energy. In the last decade, however, the prices of oil, natural gas, and coal have increased dramatically, leaving consumers and the industrial and service sectors looking for ways to reduce energy use. To achieve greater energy efficiency, we need technology, more informed consumers and producers, and investments in more energy-efficient industrial processes, businesses, residences, and transportation. As part of the America's Energy Future project, Real Prospects for Energy Efficiency in the United States examines the potential for reducing energy demand through improving efficiency by using existing technologies, technologies developed but not yet utilized widely, and prospective technologies. The book evaluates technologies based on their estimated times to initial commercial deployment, and provides an analysis of costs, barriers, and research needs. This quantitative characterization of technologies will guide policy makers toward planning the future of energy use in America. This book will also have much to offer to industry leaders, investors, environmentalists, and others looking for a practical diagnosis of energy efficiency possibilities.

Download or read book Deep Energy Retrofit Case Studies written by Ruediger Lohse and published by Springer Nature. This book was released on 2023-01-02 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes results of research conducted with the goal of providing a framework, selected tools, and guidelines to significantly reduce energy use (by more than 50%) in government and public buildings. The scope of the book is limited to public buildings that were constructed before the 1980s with low internal loads (e.g., office buildings, dormitories, barracks, public housing, and educational buildings) and that were undergoing major renovation. The book contains description and analysis of 26 well-documented case studies from Europe (Austria, Denmark, Estonia, Germany, Ireland, Latvia, Montenegro, The Netherlands, and the UK) and the USA. After these data were collected, the case studies were 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 followed. Finally, “lessons learned” were compiled and compared. Deep Energy Retrofit (DER) is a major building renovation project in which site energy use intensity (including plug loads) has been reduced by at least 50% from the pre-renovation baseline with a corresponding improvement in indoor environmental quality and comfort. Lessons learned from the case studies and experiences of the team clearly indicate that DER can be achieved with the application of “bundles” of a limited number of core technologies readily available on the market. Specific characteristics of some of these core technology bundles generally 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 [LCC] analysis).

Download or read book An Integrated Process Model And Decision Support System For Energy Efficient Retrofits written by Pelin Gultekin and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of the built environment in tackling current energy and sustainability challenges is widely recognized. There is significant value in retrofitting existing buildings. Owners, project managers, designers, and contractors now actively seek opportunities to upgrade the energy performance of standing buildings. These prospects lie in the retrofit process, within which many collaborative decisions take place at critical stages. The procedure is currently inefficient, with decision makers unaware early in the process of the ultimate implications of their actions on the energy-efficiency outcomes of the building they are creating. Thus, there is substantial room for a decision support system (DSS) that can guide facility owners and project managers in undertaking advanced energy retrofits of existing buildings by considering effects of decisions on energy performance. Approaches that support decision-making prediction in energy performance include checklists, databases, and forward and inverse modeling. We know that integrated system upgrades result in more significant energy reduction rates than do standard approaches. Because all team members do not inform these synergies early in the process, however, energy-efficient decisions do not occur. In a typical energy-efficient retrofit design, decisions are entered into simulations without collaboration to document them and predict the design's energy performance. Such late evaluations cannot go beyond the projection of energy performance that is already selected for the design. Thus, there is a need for a decision-support system that stimulates both the collaborative design process and early decision-making on system performance information.The research methodology consisted of a literature review on critical design activities and energy conservation measures (ECM) as the first stage, followed by interview design and testing the need statement with experts. Then we collected decision variables through involvement in case-study meetings and interviews with project participants. For the process delineation, we mapped three "as is" process models to cross-case with recommendations from the literature, and delivered a "to be" process model. The refined "to be" process model we offer is also fed by the ECM measure that is tracked in case studies, project participant interviews, and project documents. To inform the design team lead by PMs, a simplified comparative energy-consumption prediction methodology is developed. Consequently, this research creates a project management DSS to manage the deep-retrofit process during collaboration meetings and design charrettes. It aims to improve the integrated design process by providing a just-in-time relative energy analysis compared to a standard baseline. This energy-efficiency prediction methodology is scalable to other project values such as IEQ or cost. The knowledge we add to the field combines process with critical ECM performance measures. The opportunity to have a comparative energy analysis of decisions early in the design process will also improve system option opportunities and present the ability to change them.

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.

Book excerpt: "This report explores energy efficiency programs that target deep energy savings through substantial improvements to existing residential buildings. As states and regions set targets for reducing building-sector energy consumption, it is increasingly critical to scale up deep energy retrofit work. Only one utility-scale deep energy retrofit program exists at present in addition to several research and development projects. Deep energy retrofits aim to save 50% or more of the energy used on site in a home as compared to actual pre-retrofit usage or an estimate of energy use based on housing and climate characteristics. These savings are realized through improvements to the building shell including insulation and air sealing, and often through upgrades to high-efficiency heating, cooling, and hot water systems suited to the smaller energy load of the house. This report presents findings in four areas: workforce, retrofit measures, costs, and energy savings. We conclude by identifying barriers to scaling up deep retrofit work and strategies for overcoming them"--Publisher's description (viewed Mar. 12, 2014).

Book excerpt: Nowadays the buildings are responsible for the 40% of the world energy. The key aspects to design energy efficient buildings arises from a variety of factors and external pressures such as legislation, emissions of ozone depleting gases and public awareness of the pollution of our planet. There is a great need, among public and private sectors, to improve the energy performance of existing public buildings. Specifically indoor air quality, energy efficiency and thermal comfort conditions are the three main considerations for the good performance of buildings. Existing buildings tend to undergo performance degradations, change in use, and unexpected faults or mal - functions over time. These events often result in significant deterioration of the overall system performance, inefficient operation and unacceptable thermal comfort conditions. However, a building does not have to be new to be efficient. Today's leading building owners are retrofitting buildings, and converting existing buildings into models of sustainability. Commercial retrofit offers significant opportunities for energy efficiency and sustains - ability in the built environment. Design of energy-efficient and high-performance commercial retrofit requires that building performance and simulation tools are used and integrated with the design process.Cost-Effective Energy Efficient Building Retrofitting aims to provide building researchers and practitioners with a better understanding of how to effectively conduct commercial retrofit to promote energy conservation and sustainability including real world cases. Several general design strategies are provided in the successful completion of sustainable and energy efficient retrofit projects. It explores the current market size and why the building retrofit market has not expanded as much in past years. Review of past practice and research efforts reveals that though a building retrofit project, especially a deep retrofit project is no different than any investment case in business practice, past retrofit projects are rarely motivated and convinced by the cost-effectiveness of the project but more by building owners' desire to "green" the building.

Download or read book Development of Planning and Design Phases of an Integrative Building Lifecycle Process Model for Advanced Energy Retrofit Projects written by Sreelatha Chunduri and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced Energy Retrofit (AER) projects provide an opportunity for significant energy savings for existing buildings. They can reduce the overall environmental impact of existing facilities, while also providing long-term economic savings to the facility owner. The planning and design phases of an AER project play a significant role in defining the success or failure of the project. The process for delivering AER projects can be complex, and it is important to effectively design the delivery process to enable the design solution to effectively reduce energy consumption. This research focused on the development of an efficient and structured process for performing AER projects. It also identified the level of system integration and team collaboration that can occur in retrofit projects that are focused on reducing the energy consumption in existing buildings. A baseline Integrative Building Lifecycle Process Model (IBLPM) for the planning and design phases of retrofit buildings was developed by using literature on building systems and retrofit approaches. The baseline process model was then analyzed and validated using three detailed case studies. Two scales of retrofit projects were chosen for case study project. They included comprehensive and medium scale retrofits that contain scope for team collaboration and building system integration.After performing all the case studies, it was identified that the processes followed by both scales of retrofit projects is similar, although there were clear differences in the level of detail in the activities that were performed on the different scales of projects. A protocol that includes the validation outcomes and the evaluation criteria was developed and used to create the final planning and design phases of the IBLPM. The planning phase process map of the IBLPM gives a high level overview of the activities that needs to be performed by the owner and the project team members. The design phase process map of the IBLPM is more detailed and contains the activities that occur throughout the different phases of the integrative design process. The final outcome, the planning and design phases of the IBLPM, will aid project teams in the implementation of repeatable, consistent retrofit processes, along with the identification of important information exchanges that take place between the project participants. The IBLPM also identifies collaborative activities that need to be performed between a series of defined integrative workshops. This research work also aims to support the United States National BIM Standards initiative by providing an integrative process framework to define and structure different information exchange standards.

Book excerpt: IBACOS, in collaboration with GreenHomes America, was contracted by the New York State Energy Research and Development Authority to research exterior wall insulation solutions. This research investigated cost-effective deep energy retrofit (DER) solutions for improving the building shell exterior while achieving a cost-reduction goal, including reduced labor costs to reach a 50/50 split between material and labor. The strategies included exterior wall insulation plus energy upgrades as needed in the attic, mechanical and ventilation systems, and basement band joist, walls, and floors. The work can be integrated with other home improvements such as siding or window replacement. This strategy minimizes physical connections to existing wall studs, encapsulates existing siding materials (including lead paint) with spray foam, and creates a vented rain screen assembly to promote drying. GreenHomes America applied construction details created by IBACOS to a test home. 2x4 framing members were attached to the wall at band joists and top plates using "L" clips, with spray foam insulating the wall after framing was installed. Windows were installed simultaneously with the framing, including extension jambs. The use of clips in specific areas provided the best strength potential, and "picture framing" the spray foam held the 2x4s in place. Short-term testing was performed at this house, with monitoring equipment installed for long-term testing.

Download or read book Design Energy Simulation for Architects written by Kjell Anderson and published by Routledge. This book was released on 2014-01-23 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leading architectural firms are now using in-house design simulation to help make more sustainable design decisions. Taking advantage of these new tools requires understanding of what can be done with simulation, how to do it, and how to interpret the results. This software-agnostic book, which is intended for you to use as a professional architect, shows you how to reduce the energy use of all buildings using simulation for shading, daylighting, airflow, and energy modeling. Written by a practicing architect who specializes in design simulation, the book includes 30 case studies of net-zero buildings, as well as of projects with less lofty goals, to demonstrate how energy simulation has helped designers make early decisions. Within each case study, author Kjell Anderson mentions the software used, how the simulation was set up, and how the project team used the simulation to make design decisions. Chapters and case studies are written so that you learn general concepts without being tied to particular software. Each chapter builds on the theory from previous chapters, includes a summary of concept-level hand calculations (if applicable), and gives comprehensive explanations with graphic examples. Additional topics include simulation basics, comfort, climate analysis, a discussion on how simulation is integrated into some firms, and an overview of some popular design simulation software.
