Dataset Overview
This dataset shows the suitability of domestic properties for the installation of a Ground Source Heat Pump (GSHP).
The dataset takes into account the building size and garden size, with a property deemed suitable for a GSHP if the garden to building size ratio is greater than 2:1. This dataset does not include non-domestic properties and blocks of flats.
Figure: Green shows a building suitable for GSHP 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 then compared to the building size to calculate the ratio between them. A property that has a garden to building size ratio of greater than 2:1 is deemed suitable for a GSHP. 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 minimum ratio of garden size to building size required for the installation of a GSHP is 2:1.
Access to the garden is a barrier that is possible to overcome if required for the installation of a GSHP.
