London Building Stock Model

The Mayor is committed to cutting fuel poverty and increasing the energy efficiency of buildings across London. To help target where action is most needed, the Mayor is developing a London Building Stock Model. The model will have data on every domestic and non-domestic building in the capital.

An unacceptable number of Londoners live in fuel poverty, unable to afford to keep their homes adequately heated. Fuel poverty is caused by low incomes, high fuel costs and poor energy efficiency of a home. It creates health problems ranging from poor mental health, to childhood asthma and excess winter deaths. The Mayor’s Fuel Poverty Action Plan set out his aim to launch an open-source pan-London Energy Performance Certificate (EPC) data model. 

The Mayor has also committed to making London a zero carbon city. London’s buildings contribute around 76 per cent of the capital’s greenhouse gases, so urgent action is required to increase the number of homes and workplaces that are retrofitted with energy efficiency measures. This tool will inform our help and advice to boroughs on how to best use data to identify households in fuel poverty. It will also help them enforce the Minimum Energy Efficiency Standard (MEES) and locate the worst performing non-domestic buildings. This will make it easier to target businesses with energy efficiency programmes, particularly SMEs, to help them cut their energy bills. 

The London Building Stock Model will:  

  • be a database of all the energy and carbon data collected through the Mayor’s Energy for Londoners programmes and linked policies
  • provide a snapshot of all London’s buildings, with information on their energy performance certificates 
  • help identify the worst performing buildings and the homes most likely to be in fuel poverty 

The data will be shown in 2D map form via a browser, available from early 2020.
