Worcester, MA: Energy performance

Energy Performance
Cumulative (vs. Baseline)9%
Annual (2018)-4%

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 Worcester's portfolio consists of more than 85 buildings and 6.5 million square feet, over 14,000 streetlights, and 2 water treatment facilities.

Worcester has improved energy performance by 9% from a 2009 baseline, making progress towards a goal of 20% by 2020. Lighting, HVAC, insulation, air-sealing improvements, several oil-to-gas fuel switches, and 14 solar array installations were the prime contributors to the City's building portfolio EUI reductions. In addition, in 2017, the city completed replacing 14,000+ of its streetlights with intelligent LED fixtures.                 


Looking at the percent improvement in energy performance across all properties can provide insight into how an organization is saving energy.  Worcester has achieved energy performance improvement of greater than 10% at 30 of its properties.

There are 30 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.

Worcester's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 75 to 300 kBtu/sq. ft. The majority (59%) of properties have shown energy improvement since 2009. The properties located near or below the 0% axis may present good opportunities for further savings.
