This blog post provides details about the web tool developed by the STEEV project.
- There is a requirement by the UK government to reduce the country’s carbon emission by 80% by 2050.
- Buildings account for 45% of energy use in the UK, the equivalent of all transport and manufacturing combined (ESRC, 2009).
- Most building stock which will exist in 2050 has already been built.
- To achieve this target massive alterations of the current buildings are required. Part of the solution would be a tool that could enable planners, local authorities and government to best estimate the impact of policy changes and to target the interventions appropriately.
Cue – the STEEV demonstrator, a stakeholder engagement tool developed to visualise spatio-temporal patterns of modeled energy use and efficiency outcomes for the period of 1990-2050 – http://steevsrv.edina.ac.uk/
For a portable overview of the project download the STEEV postcard
Students, researchers, lecturers from a wide variety of disciplines/sub-disciplines, including geography, architecture, ecology, environmental science, economics, energy engineering and management.
The tool is also aimed at a range of stakeholders such as policy makers, urban developers, climate change specialists, carbon energy analysts, town planners.
Key Product Information – motivations and mechanisms
The STEEV demonstrator was developed to complement a larger project, Retrofit 2050 – Re-Engineering the City 2020-2050: Urban Foresight and Transition Management (EPSRC EP/I002162/1) which aims, through a range of stakeholders, to get a clearer understanding as to how urban transitions can be undertaken to achieve UK and international targets to reduce carbon emissions. The Retrofit 2050 project focuses on two large urban case study areas (Manchester and Neath/Port Talbot, South Wales – the latter being the focus of the STEEV demonstrator due to data availability within the project time-frame), through modelling scenarios of carbon emissions and energy use, both now and in the future.
The demonstrator itself is a client web application that enables researchers and stakeholders to look at how the spatial and temporal distribution of energy efficiency measures may impact upon likely regional outcomes for a given future state. This takes the form of a spatio-temporal exploration and visualisation tool for building-level energy efficiency modelling outputs such as the energy rating of the building, the likely energy demand of the building and the related CO2 emissions. A finite series of modelled scenario permutations have been ‘pre-built’ thus providing a limited number of parameters to be interactively altered in order to explore the spatio-temporal consequences of various policy measures.

Note: A further workpackage to establish a small area data viewer as part of the presentation layer will also be implemented shortly. This replaces the Memento geo-Timegate component of Workpackage 3.
The user interface has two main areas of activity, namely:
- three ‘pre-built’ policy scenarios which depict government investment in energy efficiency measures (from best to worst case scenario) and a user generated scenario created by selecting a combination of the energy efficiency variables which go to make up the ‘pre-built’ scenarios.
- a map viewer that enables model output values (SAP ratings, Energy use, CO2 emission) for each scenario to be viewed for each decade (1990 to 2050) at Output Area level of spatial granularity.
Further information about the policy-scenarios and variable descriptions are available from the help page

Fig. 2 – Policy scenario 2 – Low Carbon Reference (i.e. 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) has been selected for 2010. CO2 emissions have been chosen as model output value.

Energy efficiency data can be downloaded as Keyhole Markup Language (KML) files for use with the Google Earth Time Slider (for ‘pre-built’ scenarios only – see below) or as raw ASCII files complete with spatial reference for analysis in a Geographic Information System.

Members of the STEEV project presented at the following events:
- STEEV / GECO Green Energy Tech Workshop at the Edinburgh Centre on Climate Change (13 October 2011) – for further details see blog post
- The Low Carbon Research Institute 3rd Annual Conference held at the National Museum of Wales on 15-16 November 2011
- Post-Industrial Transformations – sharing knowledge and identifying opportunities, a two-day architectural symposium held at the Welsh School of Architecture on 22-23 November 2011
Post-event comments include:
“STEEV provides a new simple tool to quickly visualise a series of scenarios concerning energy consumption and carbon emissions within the complexities of the urban fabric. By facilitating the visual and historical understanding of these issues in a wider area, and for its forecasting capability considering a series of energy efficiency variables, it has a great potential to assist the planning and design processes.“ – Cristina Gonzalez-Longo (School of Architecture, University of Edinburgh)
“The STEEV system’s geospatial information on energy consumption and CO2 emissions can help planners and project developers target projects and initiatives related to energy efficiency and reduction of carbon emissions. Furthermore, the forecasting tools built into STEEV enables energy and carbon emissions to be estimated through to 2050 on the basis of alternative scenarios for energy efficiency initiatives, renewable energy, etc. This facility should help to determine where the opportunities for future emissions reductions will be, and the contributions made by existing policies and plans to future (e.g. 2020 and 2050) emissions reduction targets.” – Jim Hart (Business Manager, Edinburgh Centre for Carbon Innovation)
