ABM: Wright State University Building and Energy Solutions | ABM
“The use of a multi-faceted approach to analyze opportunities and determine the best energy saving measures to deploy shows the amount of detail and thought that went into the project. The use of a novel funding strategy and a detailed energy capital plan enabled Wright State to achieve significant energy reduction.”
--Energy Manager Today Awards judge
Wright State University faced numerous challenges in both energy consumption and the mounting inventory of deferred maintenance to replace individual boilers and chillers. The State of Ohio has established a requirement of all universities to reduce their energy spend by 20% per Executive Order House Bill 251. Wright State University needed an energy related capital improvement program, financed through a performance contracting, with guaranteed savings at no initial cost.
ABM’s Building & Energy Solutions program provided WSU with new technologies and a funding strategy that overcame these challenges. The $25 million construction project had a 20 month implementation schedule. The project helped Wright State reduce their energy consumption by 40 percent, which translates into $2 million annually in energy costs savings with cumulative guaranteed savings of $35.8 million over the 15-year term. Additionally, the project removed over 30 pieces of equipment (chillers and boilers), reducing long-term maintenance and saving over a million dollars in capital replacement costs. Tying the entire project together was the installation of pressure independent control valves, allowing Wright State to measure the Delta T at every heating and cooling coils on over 100 air-handling units.
ABM’s energy engineering team began the process by establishing the energy baseline on campus which required the acquisition of data relating to run-times, occupancy schedules, comfort demands, inventorying all assets, life cycle analysis for the HVAC assets, and a utility bill analysis. The company’s HVAC project technicians and construction managers then designed and evaluated numerous types of HVAC and other technologies as a means to eliminate energy waste while increasing student comfort. ABM’s public finance executives used this data to build the financial strategy which allowed for the implementation to be realized. Some technologies included replacing over 2000 exterior fixtures with LED lighting, lighting controls across the entire 26 buildings on campus, new arena lighting, upgraded domestic hot water systems and installation of a geothermal cooling system at the Nutter Center. The program improved indoor environmental quality, improved lighting levels, and had a dramatic effect on lowering the university’s carbon footprint.
One judge complimented the project team, pointing out its strategic approach to securing financing for the project when the client had little capital to contribute up front.
