• 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

Introduction

• 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

Agenda

• 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)

What is the 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

Why do we need a National Heat Map?

• 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

• r 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

What does the National Heat Map do?

• 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

Where did the data come from?

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.

Inputs to the heat demand model

Input (NON-RESIDENTIAL MODEL) Data source Details used Display Energy Certificates Thermal energy use and floorspace Address level characteristics Valuation Office Agency (VOA) Non Residential Ratings Database Sector and floorspace Experian PH Megafile Sector and employment Display Energy Certificates Metered energy use data Heat demand weights: CIBSE Guide F and TM46 Floorspace benchmarks DUKES Energy Use by SIC code Derived Energy use by Site, Employment and Sector Annual Business Inquiry Site and Employment Totals by SIC Code Addressing National Land and Property Gazetteer (NLPG) 2010 Address, classification and coordinate information Dataset cross-references National Energy Efficiency Data Framework (NEED) Cross-reference tables Small area gas consumption values DECC Subnational Statistics 2009 Mean gas consumption at MLSOA Metering status National Energy Efficiency Data Framework (NEED) Presence/absence of gas meter (no access to actual consumption)

• 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

Functions

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 A fraction of the cost of individual LA maps Detailed reporting Sectoral breakdown

• f buildings and heat
