A new geographical information system-based approach to map and reduce energy-related CO2 emissions from UK dwellings

This paper describes the development, demonstration and validation of an award-winning, domestic energy, carbon-counting and carbon-reduction model (DECoRuM) with the capability of measuring, modelling and mapping energy-related CO2 emissions from existing UK dwellings and aggregating them on a local scale. This enables DECoRuM to assess the cost-benefits of deploying a wide range of best practice energy efficiency measures, low carbon technologies and solar energy systems. The capabilities of DECoRuM are demonstrated by applying it to a case study in Oxford, covering 318 dwellings. The DECoRuM tool is designed to assist energy advisers and planners in local authorities to calculate and reduce CO2 emissions in the domestic sector and mitigate effects of climate change.
