Title

Heat Demand of Properties (50m Grid) - Scotland

Abstract

The Scotland Heat Map provides estimates of annual heat demand for almost 3 million properties in Scotland. Demand is given in kilowatt-hours per year (kWh/yr). Property level estimates can be combined to give values for various geographies. Both domestic and non-domestic properties are included. This raster dataset gives the total estimated heat demand of properties within 50m x 50m grid squares covering all of Scotland. Heat demand is calculated by combining data from a number of sources, ensuring that the most appropriate data available is used for each property. The data can be used by local authorities and others to identify or inform opportunities for low carbon heat projects such as district heat networks. The Scotland Heat Map is produced by the Scottish Government and aims to provide annual updates of estimates. More information can be found in the documentation available on the Scottish Government website: https://www.gov.scot/publications/scotland-heat-map-documents/

Lineage

The Scotland Heat Map was first created in 2014. It provides estimates of annual heat demand (in kilowatt-hours per year) for every property in Scotland that has a unique property reference number (UPRN). Properties that would not have a demand for heat are excluded. Heat demand is estimated using a range of data sources which can be linked together using the UPRN. The base dataset which all other information is linked to is Ordnance Survey’s (OS’s) Addressbase Plus product. The most recent release of the heat map was in July 2020. Multiple heat demand estimates can be produced for a property if information relating to its demand for heat can be found in more than one data source. Each estimate is assigned a confidence level from 1 to 5, with 5 representing values we have most confidence in and 1 least. This is mainly determined by the presence of information that would directly impact on heat demand in the source data. For example, estimates based on data that includes building type, age and floor area would be more reliable than estimates based solely on floor area derived from OS mapping data. The estimates for each property are overlaid, with those at a lower confidence level being replaced by those at a higher confidence level, where this is possible using available data. This ensures that for each property, demand is based on the most appropriate data available to the Scottish Government. Energy billing data is included for around 7,500 public sector properties in Scotland. This data is assigned confidence level 5. The data sources used for the five confidence levels in the 2020 Scotland Heat Map are as follows: Confidence level 1 - energy benchmarks (industry standard CIBSE TM46 benchmarks in kilowatt-hours per year per meter squared) for various categories of property are applied to floor areas calculated using OS mapping information. Confidence level 2 - information on property type and/or age alongside floor area from the Council Tax List and property use and floor area from the non-domestic Valuation Roll provided by the Scottish Assessors is used. CIBSE TM46 energy benchmarks are applied to non-domestic properties and a set of benchmarks derived using data from the Scottish House Condition Survey (SHCS) is used for domestic properties. Confidence level 3 – the Energy Savings Trust’s Home Analytics dataset includes a heat demand value for every domestic property in Scotland. This confidence level comprises properties from Home Analytics which do not have an energy performance certificate (EPC). Their demand for heat is obtained through a series of models based on information that would be gathered in an EPC. In this case, demand for heat is based on more detailed physical characteristics than those available at confidence level 2. Confidence level 4 – EPCs give modelled heat demand values for both domestic and non-domestic properties, although each sector uses a different model. As EPCs use a physical inspection of each property to determine the physical characteristics needed to model heat demand, they are considered more reliable than modelled records in Home Analytics. Also included here are estimates for a number of Scottish Whisky distilleries that are based on the volumes of whisky they can produce. Confidence level 5 – energy billing data has been provided by a number of Scottish councils for their properties. In addition, information on the procurement of natural gas for public sector buildings has been provided by the Scottish Government (this includes information for non-Scottish Government buildings). Together these sources provide data on actual consumption and therefore are considered to be the most reliable. In 2020, the following number of properties were assigned each confidence level: Confidence level 1 – 202,479 Confidence level 2 – 56,375 Confidence level 3 – 1,433,004 Confidence level 4 – 1,257,194 Confidence level 5 – 7,447 Total number of properties with a heat demand estimate – 2,956,499. The heat demand raster datasets give the total estimated heat demand for all properties in a given size of grid square. The 2020 release of the heat map incorporated a number of changes to the heat demand methodology when compared with earlier releases. Most importantly, the Home Analytics and non-domestic EPCs datasets were included for the first time. More information on these changes, as well as a detailed description of the heat demand methodology and an overview of other data included in the map, can be found in the Scotland Heat Map 2.0 User Guide at: https://www.gov.scot/publications/scotland-heat-map-documents/
