The National Heat Map Susannah Fairbairn CHP policy adviser Department of Energy and Climate Change (DECC) 2 nd meeting of the Concerted Action Group Core Theme 7 22 October 2013
Introduction Susannah Fairbairn CHP policy adviser at the Department of Energy and Climate Change DECC is developing a policy to support good quality natural gas CHP CHP Focus programme aims to raise awareness of existing available support for CHP
Agenda What is the National Heat Map (NHM)? Why do we need it? What does the National Heat Map do? Where did the data come from? Inputs to the heat demand model Functions – who uses it, for what and why Summary Feedback from users Questions
What is the National Heat Map? Developed by DECC and Centre for Sustainable Energy in 2012 High resolution and same functions as Google Maps Heat demand density/m²/year (space, water, process) and potential heat supply points Interactive tools assist review and navigation Finer granularity than any other map (individual buildings) Graphs to go here

Why do we need a National Heat Map? Provides evidence base for local low-carbon energy projects such as heat networks/linking Heat networks popular in UK for new housing developments in 1960/70s Rising gas prices contributed to recent resurgence in heat network popularity Local authorities have looked for ways to cut carbon emissions and address fuel poverty issues International and national energy efficiency targets need to be met 2009 Poyry report suggests residential heat networks become cost-effective in areas with heat demand density >3MW/km² Estimated that 20% of UK heat demand has at least this heat density UKDEA concluded heat networks could supply 14% of current UK heat demand by 2030, in most populous 200 UK cities and towns DECC is developing a heat networks model to better understand potential – initial results suggest up to 20% of UK domestic heat demand could be served by networks by 2030, predominantly fuelled by gas CHP, supplemented by lower carbon fuels such as biomass and biogas
What does the National Heat Map do? Primarily designed for Local Authorities Contains information on building type, heat supply and physical constraints Should be used to prioritise locations for more detailed investigation – not as a tool for designing heat networks directly or for querying energy bills Provides evidence base for local low-carbon energy projects Value for money: map cost c.£150,000 to produce. Were each local authority to produce their own map, could cost £10- 60,000 each, totalling £4-20million for the whole of England In reality, many local authorities would not undertake mapping exercise were it not for the NHM Heat Network Delivery Unit established by DECC to provide guidance and funding to local authorities in heat network development
Where did the data come from? Uses NEED framework and Ordnance Survey data Built from a bottom-up address level model of estimated heat demand Heat demand density web maps were produced from this model covering residential, commercial, industrial and public buildings, and total heat demand Based on published sub-national energy consumption statistics With exception of public buildings, map produced without access to meter readings or energy bills of individual premises None of the information used contains personal data
Inputs to the heat demand model For both residential and non-residential models, heat demand was first estimated at address level using a range of data sources. Estimates then used in a weighted disaggregation of known small-area average heating fuel consumption. The inputs to the heat demand model summarised in the following tables. Input (NON-RESIDENTIAL MODEL) Data source Details used Display Energy Certificates Thermal energy use and floorspace Valuation Office Agency (VOA) Non Address level characteristics Sector and floorspace Residential Ratings Database Experian PH Megafile Sector and employment Display Energy Certificates Metered energy use data Heat demand weights: CIBSE Guide F and TM46 Floorspace benchmarks Derived Energy use by Site, DUKES Energy Use by SIC code Employment and Sector Annual Business Inquiry Site and Employment Totals by SIC Code National Land and Property Gazetteer Address, classification and coordinate Addressing (NLPG) 2010 information National Energy Efficiency Data Dataset cross-references Cross-reference tables Framework (NEED) Small area gas consumption values DECC Subnational Statistics 2009 Mean gas consumption at MLSOA National Energy Efficiency Data Presence/absence of gas meter (no Metering status Framework (NEED) access to actual consumption)

Functions Shows local authority boundaries so assists with planning cross-boarder developments CHPs and thermal power stations Generates reports on selected areas to give accurate heat demand information and sectoral breakdown Zoom to particular areas to examine individual buildings Use the ‘street view’ function to identify building types Split screen function allows comparison of different areas, or viewing one area in different ways URL generator available to save and share research Data goes back to 2008, and is thinnest for industrial sites (doesn’t exist in NEED). Also doesn’t show things currently in development e.g. The Shard
Summary The NHM is a comprehensive spatial plan of heat demand density for England. It is equipped with a range of tools to help developers and planners identify priority areas for low-carbon energy projects Value for money Google API A fraction of the cost of individual LA User friendly and maps familiar to use Detailed reporting URL generator Sectoral breakdown Save your of buildings and heat investigations and share findings demand Precision, accuracy and cross-boarder Split screen function Zooms to reveal demand density of Examine different data individual streets and buildings, and side by side, or compare identifies cross-boarder opportunities locations
