The database used to develop regression model is based on information collected by Fannie Mae in 2012 through industry wide Energy and Water Market Research Survey. Fannie Mae surveyed more than 1100 multifamily properties across the country to collect comprehensive data about energy and water from the property managers and owners.
This dataset was then reviewed to remove any properties with missing or incorrect information associated with consumption and cost of energy and water. After cleaning the dataset, Fannie Mae published subset of 955 properties. EPA used this available dataset for further reviewing and removed additional 340 properties which have not reported total water use. Eventually, starting dataset for developing Water Score
