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. UW Health's portfolio consists of 32 buildings and more than 5 million square feet. Partner has improved energy performance by 22% from a 2013 baseline, making progress towards a goal of 34% by 2027.  Energy savings have been achieved through several retro-commissioning projects, upgrading to LED lights, energy efficient upgrades to HVAC systems, monitoring and improving air flows, and an Energy & Water team that focuses on measuring, and benchmarking to identify opportunities across the portfolio.


Looking at the percent improvement in energy performance across all properties can provide insight into how an organization is saving energy. UW Health has achieved energy performance improvements of greater than 2% at 18 of its properties, but there are 7 properties that have experienced an increase in Source EUI. These properties represent the top priorities for energy enhancements and retro-commissioning projects in the near future.


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. UW Health's portfolio consists of a wide range of EUIs, mostly between 100 and 400 kBtu/sq. ft. The majority of properties have shown energy improvement since 2013, while the properties located near or below the 0% axis may present good opportunities for further savings.


Better Buildings Waste Pilot cohort participants strive to reduce their portfolio-wide waste intensity and absolute waste, as well as increase overall waste diversion. UW Health is working towards a 35% waste diversion rate goal and a 30% recycling rate goal. As of 2021, UW Health tracked waste at two properties and achieved an overall waste diversion rate of approximately 30%.
