Hawkins\Brown has worked in partnership with the UCL Institute for Environmental Design and Engineering (IEDE), through their Engineering Doctorate program, to create the Hawkins\Brown: Emission Reduction Tool. The tool was developed as part of research titled 'Refurbish or Replace - the life cycle performance of existing buildings and their replacements' by Dr Yair Schwartz, Research Associate at The Bartlett, UCL. H\B:ERT works by measuring the volume of all materials tagged in the Revit model. It then applies embodied carbon data to that material, broken down into life cycle stages (product, construction, use stage and end of life) in line with BS EN 15978:2011.
H\B:ERT V1.1 aligns with the recent RICS and RIBA guidance and currently uses the Circular Ecology ICE database, but can use alternative data where available. To find out more about the databases used, please refer to the ‘Data Sources’ section of the H\B:ERT user guide. This allows an easy yet robust comparison between elemental design options and sets the grounds for a complete life cycle carbon footprint analysis. The tool plugs into Revit and enables the designer to quickly test the embodied carbon emissions of different material options at any time during the design process.
To find out more about the methodology behind H\B:ERT, read Dr Schwartz's paper, 'Semantically Enriched BIM Life Cycle Assessment to Enhance Buildings’ Environmental Performance'.
Or if you are interested in understanding how the plug in has been developed or you would like to contribute to its continued development you can view the source code on our GitHub repository.
