heat loss and construction

Heat loss and construction

The best way to record these details is using the EPC view of the plan. You get to the EPC view by tapping on this button in the bottom toolbar:

When in EPC view the colours will swap the other way around on the button and the plan view will change to look something like this:

How to change:

Heat loss

The default heat loss type is for HLP. To record other heat loss types:

  • Tap on the wall measurement in the red box.
  • This will give you option to choose from for different heat loss types.
  • The heat loss type will automatically run along the length of the wall unless part of this wall is part of an extension.

NB: Different heat loss types will be displayed in different colours.

Non-Separated Conservatories – Glazed Perimeter

If a room is marked as a non-separated conservatory you can select the heat loss type as glazed perimeter – this is only available for non-separated conservatories.

Alternative Walls

If you select the heat loss type as alternative you can record a different construction for the alternative wall types.

Any walls that are marked as alternative will have a wall area calculated. These areas will exclude any doors and windows added to the alternative walls. Please ensure the heights of these items have been added correctly to ensure correct calculations. Please see Item Specific Data for details.

Calculations for alternative wall areas are shown on the final EPC report.

IMPORTANT: You must have a ceiling height recorded for the alternative wall area to be calculated. See Room Specific EPC Data for more information on ceiling heights.

If you select the heat loss type as alternative you can record a different construction for the alternative wall types.

Calculations for alternative wall areas are shown on the final EPC report.

Can the wall be split into two heat loss types?

Yes. Please see how to split heat loss types for information.

Construction and insulation

You are able to record one construction type for part of the plan – main, and extensions 1-4. To do this:

  • From the EPC view tap on the options at the bottom of the screen for Main, Ext1, etc.
  • This will display the floor area for that part of the plan with the ceiling height and heat loss total.
  • At the right hand end of this it will say Construction – tap on this.
  • You can now choose from the different types of construction and insulation available.
  • Tap on OK when done.

You can also record the construction from the normal view by tapping on an external wall and selecting Construction from the popup menu.
