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. Massachusetts' portfolio consists of square footage from 43 separate state agencies. Since 2009, Massachusetts has improved energy performance by 8 percent. Energy savings have been achieved through large scale efficiency retrofits, installation of efficient fixtures and equipment, use of real-time metering to improve day-to-day operations, and education of state employees and facility residents.

Energy Performance by Facility

Looking at the percent improvement in energy performance across all departments can provide insight into how an organization is saving energy. Massachusetts has achieved energy performance improvement between 2% and 10% within 20 departments and improvement of over 15% within 7 departments. In all, 38 of the 43 agencies have seen energy reductions from the baseline, demonstrating that that energy reductions are broad and occuring across the majority of the state's portfolio.

Identifying Opportunities for Improvement

Department-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.
