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. Bullitt County Public School's portfolio consists of 27 buildings over 2 million square feet. Bullitt has improved energy performance by 21% from a 2013 baseline, surpassing their goal of 20% by 2026. The district implemented a number of energy efficiency measures over the past year including the replacement of gas-fired rooftop HVAC units with geothermal systems, upgrade of interior and exterior lighting to LED, and installation of new boilers and white foam roofing at various schools.

ENERGY PERFORMANCE BY PROPERTY

Looking at the percent improvement in energy performance across all properties can provide insight into how an organization is saving energy. Bullitt has achieved energy performance improvement of greater than 10% at 16 of its properties. There is 1 property that have experienced an increase in Source EUI. These properties have been 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. Bullitt's portfolio consists of properties with  a wide range of baseline EUI values, most of which are from 100 to 150 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. The district utilizes an extensive building automation system to monitor and adjust HVAC schedules as well as alert staff of any HVAC concerns. Bullitt benefits from active school energy teams and participation of staff in building shutdowns over weekends, school breaks, and holidays.
