This tool has been conceived and delivered by Woodknowledge Wales, the Alliance for Sustainable Building Products (ASBP) and the Good Homes Alliance (GHA) as part of the Welsh Government funded Home-Grown Homes project.
The development of the tool has been led by Richard Broad from ASBP/GHA with support from Flavie Lowres (ASBP).
The tool’s development has received considerable support from team members and associates of Woodknowledge Wales, namely:
- Gary Newman (Review/oversight)
- Toby Maclean (Embodied carbon modelling)
- Clara Koehler (Review/illustrations)
- Diana Waldron (Review/project management)
- David Hedges (Project management)
The project team would in particular like to thank the following individuals and organisations for supporting the tool’s development and providing feedback:
- Carys Mapleson for her work on an earlier version of this tool during a gap year from her Civil Engineering Degree at the University of Sheffield.
- Julie Godefroy (CIBSE) for feedback on the tool and sharing of information, particularly in regard to the use of extracts from the TM65 study ‘Embodied carbon in building services: residential heating‘.
- Clare Murray and Rania Kapitani (Levitt Bernstein) for feedback on the tool development and sharing of further information from the ‘Essex Embodied Carbon Policy Study‘.
