Energy and Water Savings in Multifamily Retrofits

This report will add to the available knowledge base by providing a detailed analysis of 236 multifamily properties that underwent energy and water retrofit projects from 2009 to 2012. This is the first study to examine a large and diverse national data set containing pre- and post-retrofit utility data for both owner- and tenant-paid energy and water accounts.7 In addition to the findings themselves, the challenges faced in performing this research provide useful insights for others seeking to understand and execute energy and water retrofits in multifamily properties.
