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 and over 2 million square feet. Bullitt has improved energy performance by 35% from a 2013 baseline, achieving their second goal of 35%. 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. With occupancy lower throughout 2020, Bullitt continued to take action to improve their energy efficiency by scaling down HVAC output in unoccupied areas. Energy consumption for 2021 was normalized to reflect reduced occupancy levels during 2021 as a result of COVID-19.

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 15% at 24 of its properties.

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.

PORTFOLIO WATER PERFORMANCE

Better Buildings Challenge Partners strive to decrease portfolio-wide source water use intensity (WUI) and to increase the percent improvement compared to a set baseline. Bullitt County Public School's portfolio consists of 27 buildings and over 2 million square feet. Partner has improved water performance by 12% from a 2013 baseline, making progress towards a goal of 20% by 2026. Bullitt continues to take action to improve their water efficiency, including detecting and repairing leaks and installing low flow fixtures. 

*2020 water consumption was significantly lower than a typical year since buildings experienced reduced occupancy due to COVID-19 disruptions.
