Description (excerpt):
Purchase College partnered with RTC Solutions Provider Brenmiller Energy and the New York Power Authority (NYPA) to implement thermal energy storage (TES) at Purchase College’s physical education building. Completed in 2023, this $2.5 million project features a Brenmiller bGen™ TES unit paired with a combined heat and power (CHP) microturbine and equipped with electric heaters for supplemental heat during peak demand, resulting in an efficient, flexible heating system that meets nearly 100% of the building’s heating needs. The case study examines how this integrated system improved the building’s energy efficiency from 28% to 60%, reduced annual emissions by an estimated 550 metric tons of CO2 equivalent, decreased operational costs, and enhanced facility resilience. Read the case study to learn how the system effectively manages varied thermal demands throughout the day and across seasons—creating a replicable blueprint for other institutions seeking to reduce carbon emissions with TES.
