20% Reduction in Energy Intensity by 2020 from a 2009 Baseline
550 Thousand Square Feet
PROGRESS TO DATE
Cumulative (vs. Baseline) 13%
Annual (2012) 10%
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. Columbia's portfolio consists of more than 25 buildings and 550 thousand square feet. Since 2009, Columbia has improved energy performance by 13 percent. Energy savings have been achieved by implementing lighting retrofits across most facilities, HVAC upgrades at two high-traffic, large facilities, and an energy awareness program focused on low-cost opportunities for savings.
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. Since 2009, Columbia has achieved energy performance improvement of greater than 15% at nine facilities. There are six facilities that have experienced an increase in Source EUI and these facilities will be targeted for future energy efficiency improvements.
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. Columbia's portfolio contains facilities with a wide range of baseline energy usage. There are a number of facilities with a baseline EUI less than 200 kBtu/sq. ft. that have already achieved energy savings of greater than 20%. There are also a number of facilities that started with EUI values above 300 kBtu/sq.ft. that have shown an increase in energy usage and may present good opportunities for savings.
