In 2012 the National Renewable Energy Laboratory (NREL) conducted a series of assessments of the U.S. Department of Energy's (DOE) proposed Home Energy Scoring Tool (HEScore). The primary objective of this work was to assess the accuracy of HEScore as it was being developed and to provide information useful to DOE program managers and HEScore development team at Lawrence Berkeley National Laboratory (LBNL). The work was documented in Roberts et al. (2012). This report is an update to the 2012 work, assessing the 2014 release of the Home Energy Scoring Tool. The analyses here follow the same methods as the previous report to facilitate comparison between the two. The analysis in this updated report focuses on energy use and the differences between versions of the Home Energy Scoring Tool.
