Before I forget (and just in time for the JISC GeoTools event on Monday) the EDINA Training Officer Viv Carr went above and beyond the call of duty to craft the definitive STEEV instructional video on Friday afternoon (25\11\11). The purpose of the camtasia broadcast is to walk users through both feature and functionality of the demonstrator.

Many thanks are also due to software engineers George Hamilton and Michael Koutroumpas who also went above and beyond the call of duty in pulling together at the last moment interface and back-end data development. This has been the difference between producing a good project deliverable and an excellent project deliverable.YouTube Preview Image

This blog post provides details about the web tool developed by the STEEV project.

Problem Space:

  • 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 –

For a portable overview of the project download the STEEV postcard

Primary Users:

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

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
  • 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)

  • 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

The STEEV demonstrator is a JavaScript client application which uses Open Layers as the mechanism for displaying the map data over the web. It also deploys a Web Map Service with temporal querying capabilities (WMS-T) to deliver Ordnance Survey open mapping products via the Digimap OpenStream API. The modelled energy efficiency variables are held in PostGIS (an open source spatial database extension to PostgreSQL)

Following on from the STEEV Usability Report recommendations and user feedback a number of requested features/functionality/bug fixes/tweaks have been committed to the EDINA Redmine butracker with view to implementation prior to the JISC GeoTools day. The resource required comes in at around 70 hours which is more than double originally estimated (due in part to the requirement to implement a ‘feature return’ functionality (at the polygon level) whereby a user can click on an individual house and the features associated with it are made explicit (SAP rating, CO2 emission, Energy Use etc)). Our GI Analyst has already facilitated this by preparing a configuration file for STEEV WFS in order to query individual buildings however there are interface and MapServer developer requirements.

A decision will be made shortly regarding developer resource in order to implement said changes.

As perparation gets underway for the forthcoming JISC Geo Tools day ((28/29 Nov.) STEEV have produced a postcard which will be distributed at the event and made available to our project partner at the Welsh School of Architecture for further outreach opportunities. Feel free to digitally send the postcard to interested colleagues.
