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. Medford's portfolio consists of approximately 20 buildings and 1.37 million square feet. Since 2009, Medford has improved energy performance by 2%. Energy savings have been achieved through both energy savings upgrades and raising awareness of building managers. Through proper use of building energy management systems, the school's property manager was able to reduce energy use significantly, in addition to portfolio-wide lighting upgrades.

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. Medford has achieved energy performance improvement of greater than 10% at 5 of its properties through lighting upgrades and raising the awareness of occupants to energy usage. There are 7 properties that have experienced an increase in Source EUI. Some of these are recreational properties that have experienced a change in usage during this period and all of these properties have been targeted for future energy efficiency improvements, including the LoConte Ice Rink, Medford's Showcase Project.

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. The majority of properties in Medford's portfolio has a baseline EUI between 50 and 200 kBtu/sq. ft. and show improvement between 0 and 30%. Properties with high baseline EUI values and low energy improvement present good opportunities for savings.
