Gossett Football House and Biology-Psychology Building are two high-energy consuming, multi-purpose buildings in the University of Maryland, College Park, Campus. This thesis details the energy analysis and energy model development for these buildings to identify energy savings opportunities. The research was conducted in three phases per building: (I)-A comprehensive summary of relevant building information collected from the energy audit walkthroughs and study of building records, followed by building utility analysis and benchmarking. (II)- Energy model development to simulate building energy consumption which was calibrated according to ASHRAE-14 guidelines. (III)- Analysis and simulation of savings from energy conservation measures to increase energy efficiency and reduce the carbon footprint of the respective buildings. Combined savings of 3,876 MMBtu, 787,290-gal water, and $100,800 per annum along with 515 MT CO2eq emission reductions per annum were projected for the two buildings. These savings directly contribute to the campus sustainability goals and increase the energy efficiency of the campus buildings.
