Minneapolis PHA: Energy performance

Cumulative (vs Baseline)5%
Annual (2018)1%
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. Minneapolis Public Housing Authority's portfolio consists of more than33 buildings and 3.4 million square feet. Partner has improved energy performance by 5% from a 2013 baseline, making progress towards a goal of 20% by 2023. Energy savings have been achieved by implementing exterior LED site lighting retrofits across all properties, stairwell LED lighting in 6 properties, installation of insulated white roofs on 4 properties, a robust, pro-active HVAC preventative maintenance program, an enhanced digital analysis of on-going mechanical systems that improves repair times, and an energy awareness program focused on low-cost opportunities for savings. In 2018 MPHA replaced numerous old style window AC units with high energy efficient models. MPHA also began its Quality Maintenance Program, a pro-active, systematic approach to preventative maintenance of occupied apartments that focuses on performing tasks that will save energy and reduce Work Orders .  Examples of tasks preformed include cleaning vertical ductwork, cleaning radiation fin tubes, added sealant around window perimeters, installing new constant air flow regulators,  fixing leak valves and faucets. 

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. Minneapolis Public Housing Authority has achieved energy performance improvement of greater than 10% at six of its properties. There are six 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. Minneapolis Public Housing Authority's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 100 to 150 kBtu/sq. ft. The majority of properties have shown energy improvement since 2013. The properties located near or below the 0% axis may present good opportunities for further savings.
