The Oxford Institute for Sustainable Development (OISD) and the Department of Architecture at Oxford Brookes University are pleased to announce a partnership between OISD: Architecture unit and the GeoInformation® Group, publishers of Cities Revealed aerial photography (www.citiesrevealed.com), to provide Carbon Mapping services using a residential property-level Geographical Information System-based CO2 emission model (DECoRuM®). The award-winning DECoRuM® model developed by Dr Rajat Gupta (Reader and Co-Director of OISD: Architecture) is able to measure, model and map emissions on a house-by-house level so that pollution hotspots can be spatially targeted. DECoRuM® can also generate scenarios for domestic emissions reductions by predicting the carbon savings and cost-benefits of deploying a range of energy efficiency measures and low/zero carbon systems in UK homes. DECoRuM® was awarded the 2006 RIBA President's award for outstanding research and has also received the southeast proof of concept (SEPOC) award in 2006-2007.
The significant advantage of DECoRuM® is that it enables local authorities to establish baseline CO2 emissions from their housing stock in a consistent and cost-effective manner. By considering 95 input parameters and through robust data reduction techniques, DECoRuM® calculates tonnes of CO2 per year or kgCO2/m2/year emitted from each individual property. These outputs are provided in a mapping database and are linked to address point records that enables CO2 emissions to be aggregated and calculated at the street, postcode, ward or authority area level. This helps local authorities that are required to seek reduction in their CO2 emissions and in the emissions within their authority area to meet government targets set through National Indicators 185 and 186.
The GeoInformation Group provides valuable input data including information on dwelling age, structural type and building height that are used within the model to generate thematic maps of baseline CO2 emissions UK homes. Alun Jones, Managing Director of The GeoInformation Group, states,
"Gathering CO2 emissions from householder surveys is subject to inaccuracies of returns and the figures produced are based on basic or reduced energy models. The DECoRuM® solution helps to provide a low-cost, authority-wide baseline model that enables residential properties to be measured quickly en masse".
Dr Rajat Gupta, the developer of the DECoRuM® model believes that:
DECoRuM® offers a next-generation academically-rigourous approach to mapping CO2 emissions from energy used in UK homes. It can help in maximising CO2 reductions in the existing housing stock and achieve carbon neutrality in new homes."
The main target users for the model include planners in local authorities, energy advisers, building surveyors and real estate professionals.
