EVENTS | ASHRAE WINTER CONFERENCE together to form complete buildings without the need for an additional superstructure) using cross-laminated timber, with the MEP installed as sub-assembly units. These assemblies were prefabricated off site, in a factory 650 miles south of the site, in Sheffield, where 95% of the MEP was installed, requiring only final connections on the island, including horizontal and vertical connections. The method allowed improved accuracy in digital modelling and optimisation, while the quality benefited from being fabricated in a clean, dry, warm environment. When delivered to site as an assembly, the construction becomes more of a product insertion rather than a full, component-based MEP installation. Cameron reported that the accelerated construction programmes provided swifter returns on investment for developers, and delivered the completed project more quickly to building users. When applied to housing projects, he considered that up to 90% of construction installation works may be completed within the factory. By referencing a 2019 independent report, Cameron suggested that they require 67% less energy than traditional building techniques, with lifetime energy savings of up to 90%, and up to 60% less waste across all disciplines, including MEP, so delivering reduced carbon footprint.
