Energy use for space heating and cooling is a significant contributor to global warming and is also highly vulnerable to the impacts of climate change. Therefore, a comprehensive understanding of future changes in building energy demand is essential for improving the resiliency of building systems and exploring demand-side solutions to achieve energy conservation and climate goals. This dissertation evaluates the impacts of climate change on building energy demand through interdisciplinary approaches and tools, including climate projections from global climate models, climate indicators for energy demand, climatic design conditions for building design, and an energy demand model.The first section of this dissertation evaluates the effects of climate change on climatic design conditions. We develop a novel method that allows the calculation of future climatic design conditions from climate projections and apply this method in Madison, Wisconsin. The results demonstrate a significant increase in heating, cooling, humidification, and dehumidification design conditions in Madison, indicating less extreme cold conditions and more extreme hot and humid conditions. The findings suggest that by the end of the century, heating and cooling loads in Madison may resemble those currently seen in St. Louis, MO and Augusta, GA, respectively. This section reveals climate change impacts on the initial stages of a building's expected lifespan and highlights the importance of considering future climatic changes from the early design stage to ensure that buildings built today satisfy future performance needs and efficiency goals.The second section of the dissertation assesses future changes in building heating and cooling demand on various timescales, including annually, monthly, and hourly. We focus on the impacts of temperature rise and population distribution for annual and monthly analysis. Results show a heating-to-cooling transition in future dominant energy demand in the eastern U.S., with more cooling-dominated states and longer cooling seasons in all states. The pattern of total energy demand will become more homogenous in the eastern U.S., and the peak energy degree-day (EDD) month will switch from winter to summer in about half of the states. For hourly analysis, we consider multiple drivers including climate, building characteristics, and air conditioning (AC) operation through an energy demand model developed by the International Institute for Applied Systems Analysis (IIASA). By downscaling the model from a daily to an hourly scale, we were able to quantify future changes in summer cooling demand in the U.S. We find that daily cooling demand during the summer months is set to increase by 28% and 45% in the U.S. by mid- and late-century, respectively. These increases are concentrated during peak hours (4-8 pm) in cities with colder climates and are distributed throughout the day in cities with warmer climates. This section provides insight into climate change impacts on energy use during building operations and highlights the role of temporal variations in climate variables in predicting building energy demand.
