Boston Housing Authority: 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. Boston Housing Authority's (BHA) portfolio consists of more than 55 buildings and 9 million square feet. Partner has improved energy performance by 4% from a 2015 baseline, making progress towards a goal of 20 by 2028. BHA's energy savings have been achieved by implementing lighting retrofits across all properties, HVAC upgrades at the three largest properties, and an energy awareness program 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. BHA has achieved energy performance improvement of greater than 10% at 14 of its properties. There are also 17 properties that have experienced an increase in Source EUI.  These properties have been targeted for future energy efficiency improvements.

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. BHA's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 100 to 250 kBtu/sq. ft. The majority of properties have shown energy improvement since 2015. The properties located near or below the 0% axis may present good opportunities for further savings.
