Atlanta Housing Authority: Energy performance

Cumulative (vs. Baseline)17%
Annual (2017)1%

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. Atlanta Housing Authority's portfolio consists of 12 properties and over 1.4 million square feet. Since 2011, Atlanta Housing Authority has improved energy performance by 17%. Energy savings have been achieved by implementing lighting retrofits and weatherization across all properties combined with HVAC upgrades at the three largest properties. 


Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. 
In addition to looking at the percent improvement in energy performance across an entire building portfolio, it can be helpful to understand the energy performance of individual properties within the portfolio. Atlanta Housing Authority has achieved energy performance improvement of greater than 10% at nine of its properties. None of its properties have experienced an increase in Source EUI.


Property-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 Housing Authority's portfolio consists of properties with a wide range of baseline EUI values, most of which are between 126 and 195 kBtu/sq. ft. All properties have shown energy improvement since 2011. The properties located near or below the 0% axis may present good opportunities for further savings.
