Door

The properties can be reviewed and edited in the Floor Plan Mode or specific sections of the Heat Load Settings. 


Below is a detailed breakdown of each result and how to manage it.


Door Area

  • What it is: The total area of the door is calculated as length multiplied by height.

  • How to review: This value can be reviewed and edited for the door's properties in Floor Plan Mode.


Door Length

  • What it is: The horizontal dimension (length) of the door.

  • How to review: Edit the length of the door's properties in the Floor Plan Mode.


Door Height

  • What it is: The vertical dimension (height) of the door.

  • How to review: Adjust the height of the door's properties in Floor Plan Mode.


Door U-Value

  • What it is: The thermal transmittance of the door is determined by its material selection.

  • How to review and edit:

    • This value can be edited in the door's properties in the Floor Plan Mode.

    • To change the default material and U-value for all doors:

      • Go to Heat Load > Materials and select a new material and U-value.

    • To adjust the U-value for a specific door, update it in its individual properties in the Floor Plan Mode.


Heat Loss Through Door

  • What It Is: The heat loss calculation is determined by the door's area, U-value, and the temperature difference between the inside and outside.

  • Formula:

    • Heat = Area × U-Value × ΔT

      • Heat: The heat loss (W in metric, BTU/h in imperial).

      • Area: The door area (m² in metric, ft² in imperial).

      • U-Value: The thermal transmittance of the door (W/m²·K in metric, BTU/h·ft²·°F in imperial).

      • ΔT: The temperature difference across the door (°C in metric, °F in imperial).

  • How to Review:

    • The door area and U-value can be reviewed in the door's properties.

    • The External Winter Temperature is set in Heat Load > General and may be auto-filled based on the project address.

      • This can be overridden in the room’s properties in the Floor Plan Mode

    • The room temperature can be overridden in the room’s properties in the Floor Plan Mode


Heat Gain Through Door

  • What It Is: The heat gain calculation is determined by the door's area, U-value, and the temperature difference between the inside and outside.

  • Formula:

    • Heat = Area × U-Value × ΔT

      • Heat: The heat gain (W in metric, BTU/h in imperial).

      • Area: The door area (m² in metric, ft² in imperial).

      • U-Value: The thermal transmittance of the door (W/m²·K in metric, BTU/h·ft²·°F in imperial).

      • ΔT: The temperature difference across the door (°C in metric, °F in imperial).

  • How to Review:

    • The door area and U-value can be reviewed in the door's properties.

    • The External Summer Temperature is set in Heat Load > General and may be auto-filled based on the project address.

      • This can be overridden in the room’s properties in the Floor Plan Mode

    • The room temperature can be overridden in the room’s properties in the Floor Plan Mode

    • To comprehensively review all door-related heat load results, export the Heat Load Report, which consolidates all calculations in one centralized document.
