New capabilities
Enhanced Heat Gain and Cooling Loads
Customers now have access to enhanced heat gain & cooling loads in h2x.
These features are now available in your account:
  • Use a weather station for annual weather and solar data
  • Model building orientation
  • Model latent and sensible internal heat sources
  • Model opaque room elements (walls, floors, ceiling/roofs)
  • Model non-opaque room elements (windows)
  • Run room & building simulations
Go to
Project Settings > Methods > Heat Gain Calculation Method > Heat Balance Method Energy Plus (Early Access)
to turn on these capabilities. Once turned on,
Project Settings > Heat Load
settings should be updated with new options for you to use in heat gain calculations.
