OpenStudio-HPXML version 0.8.0 Beta has been released. Two packages are available, a minimal zip with a handful of weather files and full zip with all US TMY3 weather files.

The OpenStudio-HPXML measure translates a HPXML building description file into a residential building model for the Department of Energy's OpenStudio/EnergyPlus building simulation platform.

OpenStudio-HPXML v0.8.0 Beta uses OpenStudio v2.9.1, EnergyPlus v9.2.0, and a proposed HPXML v3.1.

Please visit the OpenStudio-HPXML v0.8.0 Beta documentation for instructions on how to get started, how to generate an appropriate HPXML file, etc.

Breaking Changes

  • Weather cache files are now in .csv instead of .cache format.
  • extension/StandbyLoss changed to StandbyLoss for indirect water heaters.
  • Site/extension/DisableNaturalVentilation changed to BuildingConstruction/extension/FractionofOperableWindowArea for more granularity.

New Features

  • Adds a SimulationOutputReport reporting measure that provides a variety of annual/timeseries outputs in CSV format.
  • Allows modeling of whole-house fans to address cooling.
  • Improved natural ventilation algorithm that reduces the potential for incurring additional heating energy.
  • Optional HotWaterTemperature input for water heaters.
  • Optional CompressorType input for air conditioners and air-source heat pumps.
  • Allows specifying the EnergyPlus simulation timestep.
  • Runtime performance improvements.
  • Additional HPXML error-checking.

Bugfixes

  • Fix for central fan integrated supply (CFIS) fan energy.
  • Fix simulation error when FractionHeatLoadServed (or FractionCoolLoadServed) sums to slightly greater than 1.
  • Fix for running simulations on a different drive (either local or remote network).
  • Fix for HVAC sizing error when latitude is exactly 64 (Big Delta, Alaska).
  • Fixes running simulations when there is no weather cache file.
  • Fixes view factors when conditioned basement foundation walls have a window/door.
  • Fixes weather file download.
  • Allow a building with ceiling fans and without lighting.
