Scotland’s National Retrofit Centre shortlisted for GIA Sustainability Award

The project, led by Built Environment – Smarter Transformation (BE-ST) and supported by the Scottish Government’s Public Sector Heat Decarbonisation Fund, was developed in collaboration with John Gilbert Architects (JGA), Brown + Wallace, Luths Services, and Narro and delivered by main contractor Clark Contracts.

The project marks the first phase of retrofit and refurbishment works that will take place across BE-ST Innovation Campus, aiming to decarbonise the campus to achieve the International EnerPHit standard and the Scottish Net Zero Public Sector Building targets.

Taking a fabric first approach, the retrofit focused on improving the thermal efficiency of the building fabric through increased insulation and airtightness measures within the building’s heated spaces and transitioning from a gas-based heating system to a first-of-its-kind zero direct emissions system which integrated multiple systems and approaches, including hybrid heat pump systems, supported by solar PV and thermal array, mechanical ventilation with heat recovery, as well as energy-efficient lighting and controls.

Gerry Cummins, director, Clark Contracts, said: “We are delighted that this innovative project has been shortlisted at this year’s GIA Awards. Retrofit projects like this are vital as our industry works towards a more sustainable future, and it’s fantastic to see this important work being recognised.”

Gavin Johnston, associate director of collaborative and commercial partnerships, said: “We are proud that the dedication and collaborative effort of the team have been recognised through this shortlisting. This project is a true testament to what can be accomplished when collaboration is at the heart of innovation.

“Together we have delivered a complex retrofit, learned valuable lessons, and overcome challenges to create a space for the sector to gain essential retrofit training and skills.”

As part of the retrofit works, the existing curtain walling system was replaced with a new insulated Cross Laminated Timber (CLT) panel system, manufactured at BE-ST’s Mass Timber Centre of Excellence. This system is complemented by increased roof and floor insulation, which will dramatically reduce the building’s heating demands.
