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. Orlando's portfolio consists of more than 100 buildings and 6 million square feet. Orlando has improved energy performance by 10% from a 2011 baseline including both buildings and water/wastewater treatment facilities, with 18% in buildings, making progress towards a portfolio goal of 20% by 2022. As part of the Better Buildings Challenge, the City is undergoing $17.5M of energy efficiency upgrades to 56 municipal facilities, including lighting upgrades, HVAC renovations, building automation and controls, and other cost-effective energy conservation measures. Energy savings have been achieved through deep energy retrofits in 27 City buildings since 2010 that have produced an average 31% efficiency improvement.

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Orlando has achieved energy performance improvement of greater than 10% at more than 50 of its properties. There are 11 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. Orlando's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 0 to 300 kBtu/sq. ft. The majority of properties have shown energy improvement since 2011. The properties located near or below the 0% axis may present good opportunities for further savings.
