Annual (2019)3%

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. Roanoke's portfolio consists of more than 30 buildings and 1 million square feet. Since 2009, Roanoke has improved energy performance by 25%, surpassing its goal of 20% by 2022. In order to continue to improve building performance of all the properties, the in-house energy team developed a Preventive Maintenance Plan and Capital Repair Program that prioritizes improvements for lighting retrofits, HVAC and mechanical systems replacements and repairs in each building.


Looking at the percent improvement in energy performance across all properties can provide insight into how an organization is saving energy. Roanoke has achieved energy performance improvement of greater than 6% at 16 of its properties. There are 8 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. Roanoke's portfolio consists of properties with baseline EUIs ranging from 100 to 350 kBtu/sq. ft. The vast majority of properties have shown energy improvement since 2009. The properties located near or below the 0% axis may present good opportunities for further savings.
