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. Since 2010, Towson has improved energy performance by 22%.  Energy savings have been achieved by implementing major lighting upgrades and stepping up retro-commissioning and continuous commissioning efforts across multiple properties, as well as installing more efficient HVAC systems such as energy recovery systems, VRF systems and magnetic bearing chillers.  In addition, improvements included upgrading building transformers to premium efficiency type, replacing boilers with instantaneous hot water systems as well as expanding the campus wide energy management system to include nearly every campus building.  TU is a signatory of the American College & President’s Climate Commitment and the DOE Better Buildings Challenge.

ENERGY PERFORMANCE BY PROPERTY

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Towson has achieved energy performance of greater than 15% at 10 of its properties. There are 3 properties that has experienced an increase in Source EUI, which are scheduled for major renovations and will thus see significant energy 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. Towson’s portfolio consists of properties with a wide range of baseline EUI values, most of which are from 100 to 300 kBtu/sq.ft.  The majority of properties have shown energy improvement since 2010.  The energy use in two of the three top energy use buildings is driven by cooking and refrigeration equipment which present a challenge to improve.  In addition, one of the buildings houses multiple banquet halls which are leased for outside/internal events and conferences.  Almost all properties have a have a baseline EUI below 300.  The properties located near or below the 0% axis may present good opportunities for further savings.
