http://www.buildingscience.com The High R-Value Roofs Case Study Analysis is the result of BSC’s ongoing High R-Value Enclosure research — a study that BSC has undertaken for the US DOE’s Building America research program to identify and evaluate residential assemblies that cost-effectively provide 50 percent improvement in thermal resistance. daily 1 2011-07-20T08:05:50Z http://www.buildingscience.com/documents/reports/rr-1006-ba-high-r-roofs-case-study-analysis The following report is an excerpt from the 2010 Building Science Corporation Industry Team Building America Annual Report. The goal of this research is to find optimally designed, cost effective roof insulation systems that can be included with other enclosure details to help reduce whole house energy use by 70%. This report will compare a variety of roof insulating strategies and present their advantages and disadvantages according to several comparison criteria.
