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 year. Atlanta has improved energy performance by an average of 2.8 percent per year and 20% cumulatively, achieving their goal of 20 percent by 2020.  Energy savings have been achieved by implementing lighting retrofits, lighting and HVAC control system upgrades, heating and cooling equipment replacements, retro-commissioning, behavior modification, and LED street lighting.

ENERGY PERFORMANCE BY FACILITY

Atlanta’s portfolio includes properties that range in size from 1,000 sq. ft. to 3.9 million sq. ft. Building types include: offices, hospitals, K-12 schools, colleges and universities, performing arts and museums, multifamily buildings, retail centers, hotels, fire stations, recreation centers, worship facilities, and drinking water and waste water treatment plants. These properties represent a broad spectrum of building performance with ENERGY STAR® scores from 1 to 100 and baseline source EUIs from 5 to 1,301 kBtu/sq.ft., illustrating that 20 percent savings is possible across building types and sizes. Since 2011, 158 buildings, representing 38.9 percent of Atlanta’s portfolio reporting accurate energy data, have met the 20 percent energy goal ahead of the 2020 deadline.

IDENTIFYING OPPORTUNITIES FOR IMPROVEMENT

Property-level energy performance metrics, including EUI and percent improvement are critical to track progress over time and identify opportunities for additional energy savings. Atlanta's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 100 to 400 source kBtu/square feet. The majority of properties have shown a reduction in energy use intensity as compared to baseline. Properties located near or below the 0 percent axis and buildings with high baseline EUIs are presumed to represent the best opportunities for savings.
