Abstract: The design of high-performance buildings, energy storage systems, and renewable energy generation relies on hourly weather files to size and select equipment and to design control strategies. Engineers typically use Typical Meteorological Year (TMY) files, such as those produced by ASHRAE. To account for climate change, designers often turn to “morphed” TMY files. This seminar introduces a set of hourly weather files created by dynamically downscaling global climate model projections to 12-km spatial resolution. We show how these high-resolution files reveal energy-use phenomena that standard ASHRAE TMY files cannot capture.
