Kilroy Realty Corporation: Energy performance

Energy Performance
Average Annual % Improvement3%

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. Kilroy Realty's portfolio consists of more than 90 buildings and 14 million square feet. Since 2016, Kilroy has improved energy performance by an average of 3% each year.  Energy savings have been achieved through deep engagement with engineering, a dedicated capital budget for funding efficiency projects such as lighting retrofits and HVAC upgrades, the Kilroy Innovation Lab, and collaborating with tenants on energy reductions.


Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Kilroy has achieved energy performance improvement of greater than 15% at 17 of its properties. There are 34 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. Kilroy's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 100 to 250 kBtu/sq. ft. The majority of properties have shown energy improvement since 2016. The properties located near or below the 0% axis may present good opportunities for further savings.
