Measured Home Performance


Book Description

This report to the California Energy Commission's Public Interest Energy Research Program (PIER) helps Home Performance Contractors train their crews to achieve superior results in home energy retrofits. The book was updated and expanded in December of 2012 to include the impressive measured results from 15 home energy retrofits in Redding, California that were accomplished using the principles and practices outlined in this report. Homeowners may also find this information useful, when they want to understand the techniques that regularly achieve utility bill savings of 40 to 70% on an annual basis. This approach-called Measured Home Performance-is different from other means of saving energy. Most importantly, all of the home's energy features are redesigned and improved at the same time, so the synergies take effect immediately. Next, measurements are taken all the way through the process, to ensure that both the redesign and the installation are excellent. Improved comfort and energy savings are assured by high-tech field measurements, taken by the craftspeople themselves rather than by 3rd-party auditors. This process provides real-time feedback to the real decision makers-the technicians who do the work. Measurements of critical parameters like duct air leakage, while-house air leakage, supply air flow at each grill, CO concentration & draft pressure of combustion appliances and superheat and subcooling of the AC equipment make the installation quality-good or poor-are instantly clear to the crews. They can fix any shortcomings on the spot, rather than waiting days or weeks for 3rd-party testing results. Craftspeople measuring key parameters as they work transforms the workplace. Measured quality not only ensures successful results for the homeowners, it self-trains crew members in the field, where they learn more quickly than in the classroom. At the end of every day, workers know when they have achieved excellent results-a powerful motivator that works to everybody's benefit.

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. Architects and Designers seeking inspiration and technical knowledge to incorporate into their projects.

Deep Energy Retrofit Guide for Public Buildings


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 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.

Deep Energy Retrofit


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.
