Abstract: Window selection greatly influences a building's energy performance. Typical methods for choosing high performance windows include following published performance criteria, using simple decision-support tools, and performing customized simulations. This paper demonstrates, through case studies, the shortcomings of existing methods for selecting energy-efficient windows and describes a parametric simulation-based methodology with a new publically-available plug-in called WinEnergy for Grasshopper for Rhinoceros. This plug-in is an interface for the EnergyPlus building performance simulation engine and was developed with a focus on a user-friendly interface and improved data visualization capabilities. WinEnergy was then used in 192 case studies. The results were compared to other window-selection methods, including following the prescriptive fenestration requirements of ASHRAE Standard 90.1-2016 energy code.
