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. Arvada's portfolio consists of 19 buildings and 375 thousand square feet. Arvada has improved energy performance by 5% from a 2010 baseline, making progress towards a goal of 20% by 2020. Energy savings have been achieved by implementing lighting changes across all properties, including a major parking lot lighting retrofit w/ LED Lamps. HVAC fine tuning has also been performed at 3 facilities, and an energy awareness program has focused on city wide personnel for savings.

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. Arvada has achieved energy performance improvement of greater than 6% at 6 of its properties. There are 6 properties that have experienced an increase in Source EUI. These properties have been targeted for future energy efficiency improvements starting with an energy audit in conjunction with the State of Colorado Energy Department.

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. Arvada's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 100 to 300 kBtu/sq. ft. The majority of properties have shown energy improvement since 2010. The properties located near or below the 0% axis will become Arvada's focus point in the next year. Arvada is looking at state of the art HVAC trending analysis equipment and software that should identify additional savings in its control operations. The City has engaged a solicitation process for Energy Savings Performance Contracting through the Colorado Department of Energy. All major City facilities will be evaluated for energy savings opportunities.
