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. Since 2009, Atlanta has improved collective public and private energy performance by 9 percent. Atlanta's portfolio consists of approximately 50 facilities and 35 million square feet, 2 million square feet over their current commitment of 33 million square feet. The portfolio includes 3 million square feet of public facilities and 32 million square feet of private facilities. The public commitment includes several of Atlanta’s largest municipal consumers of energy: its primary drinking water treatment plant, airport parking decks, and civic center.

Focus on Private Facilities: 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. Atlanta's private portfolio has achieved energy performance improvement of up to 28%, and greater than 6% at more than 20 facilities. Six buildings have raised their ENERGY STAR scores to over 90, with one building achieving an ENERGY STAR score of 98 after reducing energy use by 25%. There are nine facilities that have experienced an increase in source EUI. These facilities have been targeted for future energy efficiency improvements.

Focus on Private Facilities: 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. Atlanta's private portfolio consists of facilities with a wide range of baseline EUI values, most of which are from 20 to 500 kBtu/square feet. The majority of facilities have shown energy improvement since 2009. Four buildings have already exceeded the 20% goal, with one achieving savings of 28%. The facilities located near or below the 0% axis and buildings with high baseline EUIs present good opportunities for savings. Atlanta has also established a water savings goal of 20% by 2020, which will further support DOE's energy savings goals through reduced energy use for water treatment and conveyance.
