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. Best Buy has achieved a 24% reduction through multiple initiatives, most notable being the implementation of a Enterprise Energy Management Platform. This new capability enables its energy analysts to have real time visibility to 18 million data points daily, allowing for the proactive resolution to identifiable abnormalities. Additional initiatives include a significant number of facilities receiving skylights with dimmable T8/T5 fluorescent lighting allowing for optimal daylight harvesting, and a number of locations receiving HVAC upgrades. Best Buy has created an integrated educational program focused on energy conservation, which they strongly encourage for all US retail associates.

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. Best Buy has achieved an energy performance improvement of 15% or greater at 635 locations and 10% or greater at 93 locations. There are 32 facilities that have experienced an increase in Source EUI. These facilities have been 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. The Best Buy portfolio consists of facilities with a wide range of baseline EUI values, most of which are from 200 to 600 kBtu/sq. ft. The vast majority of facilities have shown energy improvement since 2008. Best Buy has 13 identified energy conservation measures in process for 2013/2014, the greatest opportunities being, economizer optimization, lighting off-sets, policy adherence and mode mismatch. The facilities located near or below the 0% axis will present good savings opportunities through mechanical systems upgrades and/or technology upgrades as strategically identified.
