  • As outlined in DECC Guidance to English Energy Conservation Authorities Aim is to establish a robust baseline dataset to help LA’s: 1) Improve energy efficiency of residential accommodation in each LA area by targeting areas for action , 2) Design carbon reduction strategies and monitor CO2 changes over time 3) Monitor progress towards goals over time 4) Promote education and behaviour change 5) Work with local partners DECC have provided a number of datasets that cover key reportable metrics In addition, ofgem have information on Renewable Heat Installations and Landmark have made house by house EPC data available.
  • The data sets on the previous slide can be used to develop the ‘further’ report Additional more detailed data sets available which allow L.A’s to identify more specific opportunities that can be used to: Set realistic targets Identify practical, achievable and affordable projects Mapping can help to visualise priority areas Once specific projects have been identified, you can set realistic timescales for delivery of projects The detailed “Action Plan” can be used to drive change which can be reported via “Progress Reports” every 2 years
  • Action plan would use more detailed datasets to answer some of the following questions…. A clear action plan will help to……..
  • In summary, DECC have made a number of datasets available for reporting proposes. These cover…… Whilst these datasets provide a good way of reporting progress……also need to consider what level of detail is required to inform your action plan. i.e Do you need to be looking at Ward, Street or Dwelling level?
  • DECC consultation on change to definition of fuel poverty – ends 30 Nov 2012. Decision early 2013, alongside an updated fuel poverty strategy. Current definition: A household is considered to be in fuel poverty if it needs to spend more than 10% of its income (after tax) on fuel to maintain a satisfactory heating regime (usually 21 degrees for the main living area, and 18 degrees for other occupied rooms). Warm Homes and Energy Conservation Act 2000 – Current fuel poverty target – to ensure that as far as reasonably practicable no person lives in fuel poverty by 2016. Dual indicators separating the extent of the issue (the number of people affected) from its depth (how badly people are affected), are the way proposed to measure the problem.
  • The proposals on the way in which this will be measured are... The consultation closes in November with the proposed methodology published in early 2013
  • Beyond DECC, there are also other sources of base-line data. The HECA guidance mentions Renewable Heat as a metric. Currently no data for domestic on RHI as it won’t come into force until 2013 The Energy Saving Trust have information on Renewable Heat Premium Payment at regional level Alternatively, housing stock data can be used to quantify installations.
  • Smart meters are expected to play a major part in helping home owners reduce energy use. Whilst it is the responsibility of the energy suppliers to role our Smart meters, local authorities can help give confidence to consumers about smart metering No local authority datasets on uptake of smart meters as the mass roll out not expected until 2014
  • Beyond the datasets used for reporting progress, you may want to consider using more detailed datasets This would allow you to drill into specific opportunities at dwelling or street level. For example, which homes could benefit from: ECO RHI FiT There is already a lot of data available. For example…..
  • Since April 2012, Local Authorities have been allowed to purchase Energy Performance Certificate Data form Landmark. These “data packs” cover information on: Domestic Non domestic DECs Air conditioning inspections 3 levels of pack……
  • Small packs contain basic data on the property
  • The medium pack goes into a bit more detail, providing information on: Energy consumption Costs Floor areas … but also details which could be used to target opportunities linked to Renewable Heat. E.g. is the property off the gas network … ..or where the property could benefit from simple Energy efficiency measures such as double glazing
  • The large pack contains all information found in the small and medium packs…. But also more specific details about the energy efficiency of the property and types of heating and low/.zero carbon technology fitted to the property. This could be useful to target dwelling for PV, Renewable Heat or Green Deal and ECO eligible work.
  • Whilst the datasets are largely available, you may want to consider how you manage and interrogate the datasets. NEF have a database management tool to merge the data sets and produce standard reports These reports can be combined with mapping tools to inform your targets and develop an action plan going forward
  • Varying levels of data. Anything from LA wide to LSOA

  • HECA is BACK - making use of data

    1. 1. HECAMaking use of data Matt Cotton (NEF) Ruth Wharton (USEA)
    2. 2. “Making use of your data”• What data sets are available?• How to make use of the data• Example datasets • DECC data • ‘Other’ data• “Street by street” approach – use of housing stock data• Making sense of data through mapping
    3. 3. Baseline dataDECC datasets:•CO2 emissions•Households in fuel poverty•Cavity wall•Loft insulation•Domestic gas & electricity•FiT installationsOther sources:•RHI installations (ofgem & EST)•EPC “data packs” (Landmark)
    4. 4. How to make use of the dataDatasets Reporting ‘Further’ report (April 2013)Use detailed datasets to create an “Action Plan”•Identify street by street opportunities e.g. identify opportunities for ECOsubsidy•Set realistic targets•Identify practical, achievable and affordable projects to meet targets•Map data (using GIS) – provide better visibility ‘Progress’ report (2015….2017…..)•Set timescales for implementation
    5. 5. How to make use of the dataDeveloping an “Action plan”•Use datasets to answer the following: • Which properties may be eligible for ECO subsidy (Affordable Warmth, CSCo)? • Which properties have solid or hard to treat walls? • Where are the fuel poor households? • Are there opportunities for district heat networks (linked to new development)? • Etc…….•Clear action plan / data will help to: • Attract inward investment (e.g. Green Deal Providers / ECO subsidy / ESCOs) • Inform L.A’s looking to setup as Green Deal providers, partners or promoters • Identify priority areas (e.g. areas which can attract ECO and where there are large numbers of poorly insulated homes) • Ensure co-ordinated approach between partners – L.A, RSL’s, Green Deal Providers etc
    6. 6. How to make use of the dataDECC datasets? • Fuel Poverty - % fuel poor (LSOA level) – although criteria may change? • CO2 emissions in housing sector: • CO2 emissions (L.A level) • Domestic gas consumption (LSOA levels) • Electricity consumption (LSOA levels)DECC DATASETS • Cavity wall and loft insulation – Insulation per 10,000 homes (L.A level) • PV installations – Total number and number per 10,000 homes (L.A level) What level of data is required to develop an “Action Plan” – L.A, LSOA, Ward, Street, dwelling level?
    7. 7. Changes to the Fuel Poverty index…..Low Income High Cost approach•Households with low incomes (once fuel bills taken into account)•Fuel poverty gap – amount a household’s energy bill wouldneed to be reduced by in order for them not to be in fuelpoverty.
    8. 8. Changes to the Fuel Poverty index…..Proxies to identify households•EPCs with energy efficiency rating E,F,G(approx 81% of fuel poor)•Non-cavity wall properties•Energy pre-payment meters•Detached propertiesConsultation closes 30th November

    10. 10. ‘Other’ datasetsSmart meters•Next generation of gas and electricity meters•All UK homes to be offered a smart meter by the end of 2019 –reason = better information for customer•Energy suppliers responsible for installation•Currently no data on uptake available at L.A level•Mass roll out starting in 2014 (some already installed throughpilots and customer requests)
