I will be studying the heat recovery technologies that can potentially be implemented in existing buildings at the University of Notre Dame to reduce energy consumption in heating, cooling, lighting, and water supply systems. These processes are responsible for a large portion of energy usage, and college campuses have a duty to continually improve their sustainability and reduce their environmental footprint. It is important to consider retrofits as an option, because it would be impractical for some campuses to remove historic buildings and construct new, more efficient ones. I will perform this research by exploring heat recovery as a possible technology to be implemented at Notre Dame. I plan to learn more about approaches to upgrading buildings and understand the current energy recovery technology in mechanical systems, as well as determine why select buildings on campus already have certain forms of heat recovery. I will use this information to propose older buildings that might benefit from an application of energy recovery or an upgraded version. This will consist of a literature review and a cost analysis for retrofits at Notre Dame, which will serve as information that can be presented to Havel, Notre Dame’s current energy services company, so that they can determine how to move forward with Energy Conservation Measures, confer with the Facilities department at Notre Dame, and implement any heat recovery systems in older buildings. I will also provide website content for the Office of Sustainability, which will include technical information on the current energy conservation measures meant to educate the public on our progress as a sustainable university.
