Dataset Overview
This dataset shows the suitability of domestic properties for the installation of an Air Source Heat Pump (ASHP).
This dataset takes into account the building size, garden size and distance to neighbouring properties. A building can only be deemed suitable if it has a minimum garden size of 25m2. This dataset does not include non-domestic properties and blocks of flats.
Figure: Green shows a building suitable for ASHP installation, Grey is unsuitable.
Building data is extracted from Ordnance Survey MasterMap and Ordnance Survey AddressBase in order to determine building topography and building type information. This is then combined with land parcel data extracted from HM Land Registry and Registers of Scotland databases.
The building data and land parcel data is combined to calculate the garden size, which is used to determine the suitability of the building for an ASHP, with gardens over 25m2 being deemed suitable. The recommended heat pump size (kW) is calculated from the peak heat pump demand (kWp) of the building.
Assumptions
Due to complexities in land registration and property law, there are sometimes cases of very complex land parcels which can result in poor representation of the property area. Some land parcels are excluded, using a weighted coverage criteria, in the data cleaning process so that overlapping and or incorrectly sized land parcels do not affect the data.
The distance to the nearest neighbour is large enough to not be a barrier to installation in the majority of cases.
