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. Milwaukee's portfolio consists of more than 100 buildings and 4.5 million square feet. The City of Milwaukee has improved energy performance by 2% from a 2009 baseline, making progress towards a goal of 20% by 2022. Energy savings have been achieved in city properties by installing more efficient lighting across key properties, installing occupancy controls to shut off lights in unoccupied spaces, installing digital controls and other HVAC upgrades in key properties, adjusting thermostats, and removing unnecessary plug load devices. 

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. Milwaukee has achieved energy performance improvement of greater than 15% or greater improvement at 22 properties. The City's Energy Reduction Team continues to evaluate opportunities for energy savings in all buildings, with an emphasis on projects that have the greatest return on investment.

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. Milwaukee's portfolio consists of properties with a wide range of EUI values, sizes, and uses. The Energy Reduction Team, comprised of city facility managers and chaired by the Environmental Collaboration Office, uses Portfolio Manager and other energy analysis tools to identify opportunities for improvement, using both technology and behavioral approaches. In 2019 the City will be developing a comprehensive energy plan that will include investment grade audits of the building portfolio, establishing minimum energy efficiency buying guidelines, and fleet audit. The outcome will be an implementation roadmap to reach a 20% reduction.
