The University of the South: Energy performance

Energy Performance
Cumulative (vs. Baseline)19%
Annual (2021)-8%

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. Sewanee's portfolio consists of more than 70 buildings and 1.4 million square feet. They have improved energy performance by 19% from a 2013 baseline, making progress towards a goal of 20% by 2026. Efforts continue to evolve with full utilization of BAS features, preventative maintenance, attention to occupancy schedules, adherence to a thermal comfort policy, and on-going lighting retrofits. Energy consumption during 2020 was significantly lower than a typical year since COVID-19 disruptions resulted in temporary building closures and reduced occupancy for much of the year. 


Looking at the percent improvement in energy performance across all properties can provide insight into how an organization is saving energy. Sewanee has achieved energy performance improvement of greater than 10% at more than 30 of its properties. There are 13 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. Sewanee's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 100 to 200 kBtu/sq. ft. The majority of properties have shown energy improvement since 2013. The properties located near or below the 0% axis may present good opportunities for further savings.
