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. Parmenter's portfolio consists of more than 22 buildings and 8 million square feet. Since 2010, Parmenter has improved energy performance by an average of 2.6% each year. Energy savings have been achieved by completing building and garage lighting retrofits at various properties, optimizing and re-tuning building systems, and implementing low-cost energy savings opportunities such as lighting controls and occupancy sensors.


Looking at the percent improvement in energy performance across all properties can provide insight into how an organization is saving energy. Parmenter has achieved an average annual energy performance improvement of greater than 6% at 11 of its properties. There are 6 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. Parmenter's portfolio consists of properties with a range of baseline EUI values, most of which are between 125 to 275 kBtu/sq. ft. The majority of properties have shown energy improvement since 2010. The properties located near or below the 0% axis may present good opportunities for further savings.
