A brief description of the institution’s GHG emissions reduction initiatives:

From 2007 to 2021, UMBC’s gross square footage increased by ~25% (more space to heat, cool, light, etc.) and student enrollment increased by ~16% (more equipment plugged in, more students living on campus, more EVs being charged on campus, etc.). Based on this campus growth and associated electric demands, it would be reasonable for UMBC’s electricity consumption to increase by 15 million kWh. However, thanks to UMBC’s focus on efficiency and energy-related investments, UMBC’s electricity consumption decreased by 13.6 million kWh (~17%) which is 27 million kWh less than unmitigated growth would have required.
In other words, despite significant campus growth, UMBC used 17 percent less electricity in 2021 than in 2007. Normalized to account for campus growth, UMBC’s electricity consumption per gross square foot (kWh/GSF) was 34% less in 2021 than in 2007.
Energy conservation initiatives implemented from 2008 to 2018 include the following:
• LEED Construction – Leadership in Energy and Environmental Design (LEED) is the most widely used green building rating system in the world. LEED provides a framework that project teams apply to create highly efficient, green buildings. UMBC is committed to designing new buildings and major renovations to meet or exceed LEED Silver standards.
o Patapsco Hall Addition (LEED Gold)
o Apartment Community Center (LEED Silver)
o Performing Arts and Humanities Building (LEED Gold)
o UMBC Event Center (LEED Silver)
o ILSB (LEED GOLD)

• Central Plant Boiler Upgrades – Replaced two hot water generators with high-efficiency units and stack economizers. The high-temperature/high-pressure hot water system provides heating for two-thirds of the campus.
• Green Office Program – The GO Program is a voluntary, sustainability certification program that provides resources to assist campus offices/departments in reducing waste, conserving energy, and promoting a culture of sustainability.
• Energy Performance Contracting – EPC is a means for implementing energy-saving projects that essentially pay for themselves over time via the associated energy savings. An array of energy conservation measures were carefully evaluated, and the following projects were selected based upon operational needs and cost-effectiveness.
o Chilled Water Optimization upgraded chilled water distribution system that provides cooling for two-thirds of the campus. This project also included upgrades that enable the Thermal Energy Storage system to provide emergency chilled water distribution for critical cooling during a power outage. Completed in June 2013, this project generates annual savings of 5.7 million kWh and 3,100 MTeCO2.
o Lighting Upgrades retrofitted interior lighting fixtures throughout campus with more efficient lamps and ballasts, added occupancy sensors in many areas to automatically turn off lights, and upgraded lighting fixtures in all three parking garages with ultra-efficient LED fixtures. Completed in May 2015, this project generates annual savings of 6 million kWh and 3,200 MTeCO2.
