New York State utility regulators have approved the second OpenStudio/EnergyPlus Standardized Simulation for use by ratepayer funded programs in their state. Standardized Simulations leverage the open source OpenStudio SDK and EnergyPlus to develop transparent methods for building and running EnergyPlus simulations. The first Standardized Simulation, Custom Measure Category 5, focused on residential building envelope load reduction, helping make homes heat pump ready. The second Standardized Simulation combines equipment cold climate air source heat pump modeled with equipment-specific performance characteristics with building envelope improvement and heat pump water heaters. These types of improvement benefit greatly from the advanced building and equipment physics modeling in EnergyPlus. These methods will be used to support load reduction and decarbonization efforts in New York State. The simulations were developed by Performance Systems Development (PSD) with support from U.S. Department of Energy (DOE). DOE gave PSD a Home Energy Score Innovation Award for the first Standardized Simulation in 2022. These methods make it easier to generate a Home Energy Score by leveraging the HPXML data standard.
