Book Description
This research documents and demonstrates viable approaches using existing materials, tools and technologies in owner-conducted deep energy retrofits (DERs). These retrofits are meant to reduce energy use by 70% or more, and include extensive upgrades to the building enclosure, heating, cooling and hot water equipment, and often incorporate appliance and lighting upgrades as well as the addition of renewable energy. In this report, 11 Northern California (IECC climate zone 3) DER case studies are described and analyzed in detail, including building diagnostic tests and end-use energy monitoring results. All projects recognized the need to improve the home and its systems approximately to current building code-levels, and then pursued deeper energy reductions through either enhanced technology/ building enclosure measures, or through occupant conservation efforts, both of which achieved impressive energy performance and reductions. The beyond-code incremental DER costs averaged $25,910 for the six homes where cost data were available. DERs were affordable when these incremental costs were financed as part of a remodel, averaging a $30 per month increase in the net-cost of home ownership.

Book Description
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).

Book Description
In this paper we will present the results of monitored annual energy use data from eight residential Deep Energy Retrofit (DER) case studies using a variety of performance metrics. For each home, the details of the retrofits were analyzed, diagnostic tests to characterize the home were performed and the homes were monitored for total and individual end-use energy consumption for approximately one year. Annual performance in site and source energy, as well as carbon dioxide equivalent (CO2e) emissions were determined on a per house, per person and per square foot basis to examine the sensitivity to these different metrics. All eight DERs showed consistent success in achieving substantial site energy and CO2e reductions, but some projects achieved very little, if any source energy reduction. This problem emerged in those homes that switched from natural gas to electricity for heating and hot water, resulting in energy consumption dominated by electricity use. This demonstrates the crucial importance of selecting an appropriate metric to be used in guiding retrofit decisions. Also, due to the dynamic nature of DERs, with changes in occupancy, size, layout, and comfort, several performance metrics might be necessary to understand a project's success.

Book Description
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.

Book Description
The new threshold for green building is not just low energy, it's net-zero energy. In The New Net Zero, sustainable architect Bill Maclay charts the path for designers and builders interested in exploring green design's new-frontier net-zero-energy structures that produce as much energy as they consume and are carbon neutral. In a nation where traditional buildings use roughly 40 percent of the total fossil energy, the interest in net-zero building is growing enormously--among both designers interested in addressing climate change and consumers interested in energy efficiency and long-term savings. Maclay, an award-winning net-zero designer whose buildings have achieved high-performance goals at affordable costs, makes the case for a net-zero future; explains net-zero building metrics, integrated design practices, and renewable energy options; and shares his lessons learned on net-zero teambuilding. Designers and builders will find a wealth of state-of-the-art information on such considerations as air, water, and vapor barriers; embodied energy; residential and commercial net-zero standards; monitoring and commissioning; insulation options; costs; and more. The comprehensive overview is accompanied by several case studies, which include institutional buildings, commercial projects, and residences. Both new-building and renovation projects are covered in detail. The New Net Zero is geared toward professionals exploring net-zero design, but also suitable for nonprofessionals seeking ideas and strategies on net-zero options that are beautiful and renewably powered.

Book Description
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.

Book Description
A brand-new collection of 32 case studies that further demonstrate the retrofitting of suburbia This amply-illustrated book, second in a series, documents how defunct shopping malls, parking lots, and the past century’s other obsolete suburban development patterns are being retrofitted to address current urgent challenges they weren’t designed for: improving public health, increasing resilience in the face of climate change, leveraging social capital for equity, supporting an aging society, competing for jobs, and disrupting automobile dependence. Case Studies in Retrofitting Suburbia: Urban Design Strategies for Urgent Challenges provides summaries, data, and references on how these challenges manifest in suburbia and discussion of successful urban design strategies to address them in Part I. Part II documents how innovative design strategies are implemented in a range of northern American contexts and market conditions. From modest interventions with big ripple effects to ambitious do-overs, examples of redevelopment, reinhabitation, and regreening of changing suburban places from coast to coast are described in depth in 32 brand new case studies. Written by the authors of the highly influential Retrofitting Suburbia: Urban Design Solutions for Redesigning Suburbs Demonstrates changes that can and already have been realized in suburbia by focusing on case studies of retrofitted suburban places Illustrated in full-color with photos, maps, plans, and diagrams Full of replicable lessons and creative responses to ongoing problems and potentials with conventional suburban form, Case Studies in Retrofitting Suburbia: Urban Design Strategies for Urgent Challenges is an important book for students and professionals involved in urban design, architecture, landscape architecture, urban planning, development, civil engineering, public health, public policy, and governance. Most of all, it is intended as a useful guide for anyone who seeks to inspire revitalization, justice, and shared prosperity in places they know and care about.
