“Fully or partially glazed hinged doors and sliding doors are considered to be windows in NatHERS software tools. Only the glazed portion of a partially glazed door is to be modelled as a window. The remaining component of the partially glazed door is to be modelled as a solid door. If the glazing component is less than 25% of the door, the door may be modelled as a solid door.” |

Internal Windows Note Internal Windows (i.e. Window on a Wall between Zones) can be modelled within Hero however an Information Alert will be raised notifying the User that no Solar Gains are modelled between those Zones within Chenath. I.e. Internal Windows do not transit Light or Solar Gains between them. Their modelling impacts will be limited to conductive heat transfer losses/gains. |
Doors
