In 2009 Delaware adopted EPA’s Portfolio Manager as its primary mechanism to create an inventory of state buildings and to began tracking their energy performance. With Portfolio Manager the state has a single repository of energy performance data to identify building upgrades with the highest potential for energy savings.
Because the state’s building data had not been collected before, sustainability managers had to contact fiscal offices with the state to obtain information on utility providers and account numbers. Using existing insurance reports, utility bills, state property lists, and maintenance information, the state workgroup developed an asset inventory, in which buildings were listed by agency and prioritized based on square footage. The detailed inventory included information on age, building condition, building type, number of floors, street address and utility data.
In five years, Delaware has benchmarked 80 percent of its buildings and achieved a 17 percent energy use reduction with average annual improvement of 3 percent.
However, the state had set a goal to achieve a 30 percent reduction in energy consumption in state-owned facilities by the end of 2015 based on 2008 levels.
