Summary

The Decentralised Energy Master planning programme (DEMaP)

The Decentralised Energy Master planning programme (DEMaP), was completed in October 2010. It included a heat mapping support package for the London boroughs to enable them to carry out high resolution heat mapping for their area.

To date, heat maps have been produced for 29 London boroughs with the remaining four boroughs carrying out their own data collection. All of the data collected through this process is provided below.

Carbon Calculator Tool

Arup have produced a Carbon Calculator Tool to assist projects in their early estimation of the carbon dioxide (CO2) savings which could be realised by a district heating scheme with different sources of heating.

The calculator's estimates include the impact of a decarbonising the electrical grid over time, based on projections by the Department for Energy and Climate Change, as well as the Government's Standard Assessment Procedure (SAP).

The Excel-based tool can be downloaded below.

Borough Heat Maps Data and Reports (2012)

In March 2012, all London boroughs did a heat mapping exercise. The data from this includes the following and can be downloaded below:

  • Heat Load for all boroughs
  • Heat Supplies for all boroughs
  • Heat Network
  • LDD 2010 database

The borough heat maps data contains real heat consumption data for priority buildings such as hospitals, leisure centres and local authority buildings.

As part of this work, each of the boroughs developed implementation plans to help them take the DE opportunities identified to the next stages. The implementation plans include barriers and opportunities, actions to be taken by the council, key dates, personnel responsible. These can be downloaded below.
