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. PPSD's portfolio consists of more than 80 buildings and 8 million square feet. Since 2009, PPSD has improved energy performance by 3%. Energy savings have been achieved by implementing Recovery Zone Bond Energy Efficiency Projects, which range from whole energy retrofit projects, DDC retrofits, steam valves and traps replacement, and pipe insulation. Savings have also been achieved from boiler burner upgrades at 47 sites. Energy savings have also been achieved through an focus on behavioral conservation, and improved building operations.

Energy Performance by Facility

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. PPSD has achieved energy performance improvement of greater than 10% at more than 20 of its facilities. There are 42 facilities that have experienced an increase in Source EUI. These facilities may be targeted for future energy efficiency improvements.

Identifying Opportunities for Improvement

Facility-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. PPSD portfolio consists mostly of facilities with baseline EUIs ranging from 75 to 150 kBtu/sq. ft. The vast majority of facilities have shown energy improvement since 2009. The facilities located near or below the 0% axis may present good opportunities for further savings.
