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. Pittsburgh's portfolio consists of more than 130 buildings and 1.7 million square feet. Pittsburgh has improved energy performance by 4% from a 2010 baseline, making progress towards a goal of 20% by 2020. Energy savings have been achieved by implementing a series of retrofits and upgrades across all facilities, including the addition of solar, the installation of cool roofs, lighting upgrades, repairs to its system of steam tunnels, HVAC equipment upgrades and the addition of lighting control systems.

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. Pittsburgh has achieved energy performance improvement of 10% or greater at 45 of its properties. There are 42 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. Pittsburgh'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 2010. The properties located near or below the 0% axis may present good opportunities for further savings.
