King County 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. King County Housing Authority's portfolio consists of more than 110 properties and 7 million square feet. King County house Authority has improved energy performance by 8% from a 2013 baseline, making progress towards a goal of 20% by 2026. Energy savings have been achieved by implementing lighting retrofits across all properties, HVAC upgrades at commercial buildings, an Energy Performance Contract for lighting and heating upgrades at 35 public housing properties, weatherization upgrades were completed at roughly 30 properties, and an energy awareness program for residents 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. King County Housing Authority has achieved energy performance improvement of greater than 10% at 40 of its properties. There are 22 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. King County Housing Authority's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 50 to 150 kBtu/sq. ft. The majority of properties have shown energy improvement since 2013. The properties located near or below the 0% axis may present good opportunities for further savings.
