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. 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. Tower has committed 11 buildings that they both own and manage, which make up 2.5 million square feet of multi-tenant commercial office and multi-family high-rise residential properties. Compared to a 2010 baseline, Tower has improved energy performance by 24% due in large part to implementing a Real-Time Energy Management Program focused on low-cost ECMs and sustainable operations, LED lighting retrofits, BMS control upgrades, and equipment upgrades. Energy consumption during 2020 was significantly lower than a typical year since COVID-19 disruptions resulted in temporary building closures and reduced occupancy for much of the year. 

PORTFOLIO WASTE PERFORMANCE

Better Buildings Waste Pilot cohort participants strive to reduce their portfolio-wide waste intensity and increase overall waste diversion. Tower Companies is working towards a goal of 75% waste diversion by 2025. As of 2020, Tower Companies tracked waste data at 10 facilities and achieved an overall waste diversion rate of approximately 56%, a slight improvement from a 2017 baseline of 55%. The baseline was set in 2017 because it is the most recent year that Tower had a full data set for the committed portfolio. Tower has been focused on waste diversion for many years and has continuously improved. Their success is driven by tenant engagement, thoughtful signage, comprehensive composting and recycling programs, waste audits, and dedicated employee teams that have incorporated waste best practices into building management.
