Buildings; Energy Efficiency


In the fall of 2009, researchers at the Florida Solar Energy Center (FSEC) began working with affordable housing entities that were conducting major renovation projects in unoccupied, foreclosed homes. The study was funded by the Florida Energy Systems Consortium and the U.S. Department of Energy's Building America program. When components and equipment were being replaced because they were worn out, researchers provided savings projections for higher-efficiency choices. Savings were also projected for improvements that were strictly for energy efficiency, such as adding ceiling insulation. The best practices summarized in this document are a mixture of assessment, design, specification, quality assurance, and verification measures. They represent either the most commonly adopted practice observed in this field work or, in some cases, the highest performance practice that did not involve additional cost. For example, although "medium" was the most commonly chosen exterior paint color, "white" is the highest performing color and herein the recommended practice. Additional building science measures from the ENERGY STAR for Homes program and Department of Energy's Challenge Home programs have been included in the best practices to address occupant health, safety, building durability, and comfort concerns.
