STEEV - Spatio-Temporal Energy Efficiency Visualisation

Title

Spatio-Temporal Energy Efficiency Visualisations

Acronym

STEEV

Duration

February 2011 – November 2011

Summary

This project will build a stakeholder engagement tool visualising historic, current and future energy efficiency estimates at the level of individual buildings. Researchers exploring and investigating policy options on possible future states of the built environment need a simple mechanism to visually analyse and compare outcomes of different scenarios of urban energy reduction policy. STEEV will produce modelled estimates of building energy use for the period 2000-2050 for a sample geographic area in Cardiff, South Wales and provide a web-based application that allows researchers, policy-makers and other stakeholders the facility to explore varying spatio-temporal patterns of energy efficiency outcomes. We will also explore a novel usage of the Memento framework by enabling 'time-travel' both backwards ('web-time') and forwards ('content-time').

Further work will provide insights into aspects of temporal modelling of the Ordnance Survey large scale geographic database, MasterMap. The latter will inform how adaptations to the JISC Digimap service might be best optimised to provide access to historic versions of this and similar resources. A range of outputs are envisaged - from a demonstrator web client aimed at the stakeholder research group needs, an experimental Memento geo-Timegate allowing issues related to 'content-time' to be unearthed and a schema and delivery mechanism for future delivery of temporal snapshots of large-scalemapping databases.

Project Deliverables

The key deliverables will be:

A database of building-level energy efficiency coefficients for 2000-2050 for a large sample area within South East Wales;
A database schema for exposing the model outputs via a WMS-T;
A WMS delivering the data visualisations;
A WMS-T allowing temporal navigation;
Tile Cached versions of the above allowing direct URI mapping to resources;
A Memento geo-Timegate and proxy allowing translation of Memento requests into WMS-T ones;
An evaluation report detailing our experiences with 'Web' and 'Content' time;
A Web Client (OpenLayers based) allowing user interaction and visualisation of the modelled outputs under variable input scenarios;
Potentially, demonstration of the outputs, visualised and temporally query-able in a Google Earth client;
User needs requirements/ problem and issue refinement.
