H\B:ERT Emission Reduction Tool developed by IEDE & Hawkins/Brown shortlisted for AJ100 Awards 2019

21 May 2019

The tool kit was developed by UCL Research Associate Yair Schwartz in partnership with Hawkins/Brown as part of IEDE's Engineering Doctorate Program


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. The tool aligns with the recent RICS and RIBA guidance and currently uses the University of Bath ICE database 2011, but can use alternative data where available. 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.

Hawkins/Brown architecture practice have been nominated in the category of Sustainable Practice of the year by AJ100 in recognition of the significance of the tool.  The nomination commends the growth of sustainable practice fostered by IEDE's partnership with Hawkins/Brown and recognises the significant impact of IEDE research on industry practice. 

The winner of this year’s awards will be announced at the annual AJ100 gala dinner event on 19 June at the Tower of London and the full short list of nominations can be read here.
