Following the theoretical exercise, and as Tritax Symmetry had exchanged an Agreement for Lease with Co-op for a 660,000 sq ft building in Biggleswade, the working group was challenged with undertaking a pilot study of this building, both in its specific Co-op required form and also adjusted to reflect the same building constructed to our standard specification.
Modelling was undertaken by Ridge based upon the tendered data and quantification available with ongoing liaison with UKGBC to ensure alignment with their framework definition.
Meetings were held with key members of the supply
chain including Kingspan and CA Group to review their environmental product data and explore initiatives that are in place to review embodied carbon.
In December 2019, Ridge issued their report with regards to the Biggleswade project. It was apparent that a significant and disproportionate tonnage of embodied carbon sat within the concrete ground floor slabs and service yards, contributing just below 40% of the embodied carbon.
The study included a review of the options available for carbon offset, with two offset vehicles being recognised by UKGBC that are subject to stringent evaluation to ensure they are credible and ethical.
The conclusion of the study being that the delivery of new buildings to be net zero carbon in construction to accord with the UKGBC Framework Definition is a realistic proposal.
