Portfolio 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. Denver's portfolio consists of more than 140 buildings and 7 million square feet. Since 2011, Denver has improved energy performance by 6%. Energy savings have been achieved by implementing various capital improvements, retro-commissioning in numerous facilities including 5 of the City's largest energy users, and creating a culture of efficiency.

Energy Performance by Facility

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Denver has achieved energy performance improvement of greater than 6% at 40 of its facilities. There are 60 facilities that have experienced an increase in Source EUI. Some of these have recently expanded hours as a result of the improved economy. We will continue to work with these facilities to identify opportunities to improve efficiency.

Identifying Opportunities for Improvement

Facility-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. Denver's portfolio consists of facilities with a wide range of baseline EUI values, most of which are from 100 to 300 kBtu/sq. ft. The majority of facilities have shown energy improvement since 2011. The facilities located near or below the 0% axis may present good opportunities for further savings and will be looked at in the coming year.
