Philadelphia, PA: Energy performance

Energy Performance
Cumulative (vs. Baseline)11%
Annual (2019)3%

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. The City of Philadelphia's portfolio consists of more than 25 buildings and 15 million square feet. The City of Philadelphia has improved energy performance by 11% from a 2013 baseline, making progress towards a goal of 20% by 2023. Energy savings have been achieved by implementing lighting and occupancy sensor upgrades, building automation system upgrades, and other energy efficiency projects through the City's Greenworks Sustainability Fund. The largest project implemented to date was a Guaranteed Energy Savings project at the City's four largest downtown buildings. The City is also implementing a Guaranteed Energy Savings project at the Philadelphia Museum of Art which builds onto a current renovation project to include energy efficiency measures. The City also runs an Energy Efficiency Incentive Program pilot focused on low-cost opportunities for savings.


Looking at the percent improvement in energy performance across all properties can provide insight into how an organization is saving energy. The City of Philadelphia has achieved energy performance improvement of 10% or greater at 12 of its properties. There is 1 property that has experienced an increase in Source EUI. This property is being targeted for future energy efficiency improvements within the City's Energy Efficiency and Sustainability Fund.


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. The City of Philadelphia's portfolio consists of properties with a wide range of building types and baseline EUI values, most of which are from about 100 to 600 kBtu/sq. ft. The majority of the City's properties have shown energy improvement since 2013. The properties located near or below the 0% axis present good opportunities to target for further savings.
