Energy Performance


20% Reduction in Energy Intensity by 2020 from a 2009 Baseline


50 Million Square Feet


Cumulative (vs. Baseline) 9%
Annual (2013) 2%


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 energy performance by 9% for a diverse portfolio of properties representing private, local government, federal government, education, and nonprofit sectors. Atlanta's portfolio consists of more than 100 facilities and 50 million square feet. The portfolio includes 5 million square feet of public facilities and 45 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.

Energy Performance by Facility

Atlanta’s portfolio includes facilities that range in size from less than 3,000 square feet to more than 7 million square feet. Facilities in our portfolio include: small to large office, hospitals, performing arts/museums, K-12, pre-school/daycare, multifamily, retail, hotels, fire stations, recreation, worship, and water treatment. These facilities represent a broad spectrum of baseline building performance with baseline Energy Star scores that range from 3 to 94, which will illustrate through example that 20% savings is possible in any typical facility. Since 2011, 17 of the more than 100 buildings in Atlanta’s portfolio, have met or exceeded the 20% goal.

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 100 to 400 source kBtu/square feet. The majority of facilities have shown energy improvement since 2009. 17 buildings have already exceeded the 20% goal, with one achieving savings of 51%. Facilities located near or below the 0% axis and buildings with high baseline EUIs are presumed to represent the best opportunities for savings.
