20% Reduction in Energy Intensity by 2020 from a 2009 Baseline
5 Million Square Feet
PROGRESS TO DATE
Cumulative (vs. Baseline) 8%
Annual (2013) -2%
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. Energy savings have been achieved in City facilities by installing more efficient lighting across key facilities, installing occupancy controls to shut off lights in unoccupied spaces, installing digital controls and other HVAC upgrades in key facilities, adjusting thermostats, and removing unnecessary plug load devices. The City of Milwaukee has supported energy efficiency projects among privately owned buildings in the challenge through the Milwaukee Energy Efficiency program (Me2).
Energy Performance by Facility
Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Milwaukee has achieved energy performance improvement of greater than 6% at more than 50 of its facilities and 15% or greater improvement in 20 facilities. 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
Facility-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 facilities with a wide range of EUI values, sizes, and uses. The Energy Reduction Team, comprised of City facility managers and chaired by the Office of Environmental Sustainability, uses Portfolio Manager and other energy analysis tools to identify opportunities for improvement, using both technology and behavioral approaches.
