Energy Performance

Better Buildings Challenge Partners strive to decrease portfolio-wide source energy use intensity (EUI) and to increase the percent improvement compared to a set baseline. Maryland's portfolio consists of more than 75 properties and 9 million square feet. Since 2008, Maryland has improved energy performance by 23%. Significant energy savings have been achieved through large-scale Energy Performance Contracts. Measures include lighting retrofits, lighting occupancy controls, facility management controls, submetering, and mechanical system improvements.

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Maryland has achieved energy performance improvement of greater than 10% at 29 of its properties. There are 22 properties that have experienced an increase in Source EUI.  These properties have been targeted for future energy efficiency improvements.

Property-level energy performance metrics, including EUI and percent improvement to date, are critical to track progress over time and identify opportunities for additional energy savings. Maryland's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 100 to 300  kBtu/sq. ft. The majority of properties have shown energy improvement since 2008. The properties located near or below the 0% axis may present good opportunities for further savings.
