Community College of Allegheny County: Energy performance

Energy Performance
Cumulative (vs. Baseline)8%

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. CCAC's portfolio consists of 18 buildings and 1.5 million square feet. CCAC has improved energy performance by 8% from a 2014 baseline, making progress towards a goal of 20% by 2024. Energy savings have been achieved by implementing major HVAC plant replacement and lighting retrofits at CCAC's largest single energy user as well as lighting, HVAC, and control upgrades across all college facilities. The CCAC Board has passed an energy policy, and guidelines are being developed. Thirteen Physical Plant personnel, both supervisory and union, have completed Building Operator Certification classes.

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.  CCAC has achieved energy performance improvement of greater than 15% at 2 of its properties. There are 4 properties that have experienced an increase in Source EUI. One of them has experienced a significant increase in usage, with a new, very popular program being added. Another property has added a new, rather energy-intensive fine arts building (with specialized exhaust, kilns, and other equipment). In two facilities, a digital display has been added that has caused an increase in energy use. These properties have been targeted for future energy efficiency improvements. The controls for the digital signage will be modified, and more efficient HVAC equipment is being installed.

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. CCAC's portfolio consists of properties with a wide range of baseline EUI values, most of which range from 150 to 200 kBtu/sq. ft. The majority of properties have shown energy improvement since 2014. The properties located near or below the 0% axis present good opportunities for further savings, and several such projects are scheduled to take place in the very near future. One of these properties contains the College's data center, where an energy audit and a phased schedule of improvements are taking place to reduce energy use.  Other properties have major improvements in the works.
