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. Seattle's portfolio consists of 146 buildings and 7.6 million square feet. Partner has improved energy performance by 18% from a 2011 baseline, making progress towards a goal of 20% by 2020. Energy savings have largely been achieved through a regular program of facility audits followed by controls tuning and capital improvements.  Our primary focus has been on tuning existing systems, LED lighting retrofits and high-efficiency HVAC upgrades.

ENERGY PERFORMANCE BY PROPERTY

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Seattle has achieved energy performance improvement of greater than 15% at more than 44 of its properties. There are 38 properties 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. Seattle's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 50 to 500 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.
