Door

The Door Results focus on calculations related to Heat Loss and Heat Gain. These values depend on the Door’s Material and the temperature difference on both sides. 

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.

Heat Loss Through Door = Area × U-Value × ΔT (Formula)

Where:

  • 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.

Heat Gain Through Door = Area × U-Value × ΔT (Formula)

Where:

  • 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
