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. Penn State's portfolio consists of 21 campuses and more than 28 million square feet. Penn State has improved energy performance by 7% from a 2013 baseline, making progress towards a goal of 20% by 2025.  Energy savings have been achieved in campus buildings by continuing and expanding efforts such as the Energy Savings Program and Continuous Commissioning Program, and through efficiency improvements in district energy systems.

ENERGY PERFORMANCE BY CAMPUS

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. PSU has achieved energy performance improvement of at least 5% at 12 of its campuses, representing 18% of building space enrolled.  Locations with the largest consumption have the greatest potential for reductions and will continue to be targeted.  Campuses that have experienced an increase in Source EUI will also be targeted for future energy efficiency improvements.

IDENTIFYING OPPORTUNITIES FOR IMPROVEMENT

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. PSU's portfolio consists of campuses with a wide range of baseline EUI values, most of which are from 125 to 250 kBtu/sq. ft.  Universities traditionally have properties with a wide range of uses contributing to the energy consumption, with examples such as student housing, classroom buildings, and scientific research laboratories.  The campuses located near or below the 0% axis may present good opportunities for further savings, while it is also useful to compare properties with similar use profiles.
