Presentation on the Spatio-Temporal Energy Efficiency Visualisation (STEEV) tool (http://steevsrv.edina.ac.uk/) given by Stuart Macdonald, EDINA, at the JISC GECO/STEEV Green Energy Tech Event (#e3vis) on Thursday 13th October 2011.

3. Researchers investigating policy options on possible future states of the built environment need a simple mechanism to visualise outcomes of different scenarios of urban energy reduction policy Background: There is a requirement by the UK government to reduce the country’s carbon emission by 80% by 2050. Most building stock which will exist in 2050 has already been built; thus to achieve this target massive alterations of the current buildings are required.

4. STEEV is a JISC-funded project (Feb. 2011 – Oct. 2011) Information Environment Programme: Geospatial strand Project Partner: Welsh School of Architecture, Cardiff University This project will build a stakeholder engagement tool visualising historic, current and future energy efficiency estimates for small area geographies. Modelled estimates of building energy use for the period 1990-2050 for area in South Wales generated by the Energy and Environmental Prediction model

5. For further information see: http://www.cardiff.ac.uk/archi/programmes/cost8/case/assessment/eep.html Energy and Environmental Prediction (EEP) Model A digital auditing tool for quantifying energy use and associated emissions for cities to help plan to reduce carbon dioxide and other emissions. The domestic sub-model assigns properties into 100 different types. Each type has a CO2 emission, SAP rating and yearly energy cost associated with it. Every property within the region is surveyed and classified as a 'type'. Predictions can be made of potential CO2 and energy savings that can be made by installing various energy efficiency measures.

7. Scenario 1 – Faint Hearted - business as usual Minor attempts to decarbonise the grid Scenario 2 – Low Carbon Reference - partial decarbonisation Large investment in energy efficiency and small scale renewables - some change in occupant behaviour. Scenario 3 – Super Ambitious - full decarbonisation Through renewables and nuclear, and huge investment in energy efficiency and small scale renewables. Large scale change in occupant behaviour Govt. Policy Scenario descriptions

8. The Grid The government plans to reduce this emission rate by decarbonising the grid. This slider represents the government policy range from business as usual to super ambitious decarbonisation. Renewables, This slider selects the number of solar panels installed on buildings, Energy Efficiency This slider represents energy use reduction in the home (via insulation, new boilers, double glazing) Occupant Behaviour The way people use their houses has an impact on energy use. This slider changes the indoor temperature of the house set by the occupant Variable descriptions

9. The government plans to reduce this emission rate by decarbonising the grid. This slider represents the government policy range from business as usual to super ambitious decarbonisation. Output model unit of analysis: SAP Value, Energy Use (KWh per annum), CO2 emissions (Kg per annum) Download raw ASCII data for all scenarios or KML for policy-based scenarios (forthcoming) The government invests in partial decarbonisation of the grid through reduced dependence on fossil fuels. Large investment in energy efficiency and small scale renewable, some change in occupant behaviour. The way people use their houses has an impact on energy use, this slider changes the indoor temperature of the house set by the occupant it varies from 21 degrees C to 17 degrees C representing a business as usual scenario to lower expectation and more clothes worn.
