Carbon Calculations

The total embodied carbon has been calculated using the ICE Database V3.0. Each component has been valued and the numbers to the left of each project material corresponds to the numbers on the exploded drawing on the previous page. The calculated embodied carbon has been worked out using EPD information and ICE database A1-A3, this includes material extraction (A1), transport to the manufacturer (A2) and manufacturing (A3) (WorldGBC).

 

The project is below the embodied carbon for housing, offices and schools for the LETI Climate Emergency

Design Guide (LETI, 2019). The project also meets the RIBA 2030 targets for embodied carbon (RIBA, 2019). Although these targets are met, the calculation will increase when you factor in transport to the site (A4) and installation on site (A5). Furthermore, not every building component has been considered when calculating the embodied carbon. To limit the impact of A4 and A5 on the embodied carbon of the project, products are to be sourced as close as possible to site and much of the installation on the site will be as efficient as possible.

 

The project aims to take advantage of circular material selection and benefits from being demountable and recyclable. The concrete used in the project will use recycled and reclaimed aggregate that can be up to 70% of the aggregate mix.
