Creating a Floor Plan

Starting a floor plan

When you create a project, you will be prompted to select a material palette. This sets the default material used in the heat loss calculation. You are then prompted to enter the default height for the rooms in the property. 

All of these details can be adjusted as you construct your floor plan.

If you are a pro user, at this point you can upload a floor plan PDF to use as a backdrop when creating your plan. 

Examples 

• Join our weekly training session for a live example. 
• Quick demo using the import plans feature. 

Creating rooms

Drag and drop a room from the left-hand menu into position and resize to the correct shape. If not using an uploaded floor plan, click the corners of the room to view the dimensions. If using an uploaded floor plan, you can rely on aligning the rooms with the plan below. 

Adjusting room properties

Click each room to view the following options:

	Change height Adjust the height of the room. Input the height and click the tick to save or the cross to cancel.
	Flue Select whether there is a flue. Choose from: no flue, throat restrictor fitted to flue, no throat restrictor fitted to flue.
	Edit name Change the name of the room.
	Select room type Each room needs a type as this determines the ACH, temperature and default name for the room. Select from pre-set options or create a custom room.
	Delete Remove the room from the floor plan

Note if ceiling regions are added later they will override height for the room. 

Adjusting wall properties

Click the walls to view the following options: 

	Change material  Click to view and select from the material options for this palette. Click Add Materials to adjust the palette.
	External temperature  Set the temperature of the region on the other side of this wall. This will default to the ODT and can be adjusted for walls adjoining unheated spaces or neighbouring properties.

External and internal walls

Each wall is either an external or internal wall. This is detected automatically based on whether there is an adjoining room. 

As you drag rooms into your plan, it's important that they lock together with existing walls correctly so external/internal walls are correctly identified. Only external walls will have the external temperature setting, external walls are also a darker grey colour.

Walls should not overlap and there typically should not be external walls within the interior of a property. Below are some common errors that will lead to errors in the heat loss calculation. 

Don't overlap walls
Don't leave large gaps between internal walls

Adding radiators, doors and windows

Internal doors do not need to be included in the floor plan. Rooms with open doorways should typically be modelled as one room. 

Drag and drop a radiator, door or window from the left-hand menu into the room and snap it into position on a wall. Click the component to view and adjust the following options:

	Change material or type Click to view and select from the material options for the selected palette. Click Add Materials to edit the palette.
	Adjust dimensions Input the width and height, then tick to save or cross to cancel. This option will not be available for custom radiators which require a different P50 for each radiator size.
	Delete Remove the component from the floor plan

Adding floors

You can add different floors by clicking Add Level. Move between floors using the expanded view in the bottom-right. 

You can change the ceiling height on the whole floor by clicking on the three dots to the right of the relevant floor and selecting Edit. You can also change the name of the floor here. To delete an entire floor, select Delete. 

Where the floor and ceiling materials are the default on the selected palette, there is no need to add a region. If the floor and ceiling region has a different material or height to the rest of the space, you can use regions to model this.

A light grey footprint of the floor below will be displayed, ensure the above rooms are correctly aligned with the floor below. Misalignment will lead to errors in the heat loss.
