CLARK Contracts has announced the completion of the retrofit of Scotland’s National Retrofit Centre (SNRC) for Built Environment – Smarter Transformation (BE-ST).
Developed in collaboration with John Gilbert Architects (JGA), Luths Services, and Narro Associates, the retrofit marks the first phase of retrofit and refurbishment works that will take place across BE-ST’s Innovation Campus, with the aim of achieving the International EnerPHit standard and the Scottish Net Zero Public Sector Building targets.
Taking a fabric first approach, the work 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.
The existing curtain walling system was replaced with a new insulated CLT panel system, manufactured at BE-ST’s Mass Timber Centre of Excellence. This is complemented by increased roof and floor insulation.
During the project, Clark Contracts, BE-ST, and JGA held numerous ‘Behind the Build’ events which gave industry professionals a behind the scenes look at the project at each stage. Tours have also been facilitated for students from Edinburgh Napier University and Clark Contracts’ academy.
The project was part-funded through Phase 1 of Scotland’s Public Sector Heat Decarbonisation Fund. Edinburgh Napier University, administrator of BE-ST, was awarded £1.2 million through the fund, which is delivered by Salix on behalf of the Scottish Government.
The SNRC will serve as a demonstrator of complex retrofit solutions and a centre for excellence in retrofit training, upskilling, and knowledge exchange. It will offer a range of resources, including testing and training rigs, workshops, and events. The SNRC will also showcase technologies and retrofit methods, designed to accelerate the development and adoption of scalable, high-quality solutions.
Gerry Cummins, Clark Contracts director, said, “We’re proud to have successfully delivered the refurbishment of Scotland’s National Retrofit Centre for BE-ST, a project that will play a vital role in advancing the nation’s net zero ambitions. This was a highly collaborative effort, and our team worked closely with all partners to deliver a high-quality, future-focused space that supports innovation in sustainable construction. It’s an honour to contribute to such an important step forward for the built environment in Scotland.”
Stephen Good, CEO at BE-ST, added, “The Scottish National Retrofit Centre marks a major step forward in Scotland’s journey to decarbonising the built environment. More than just a facility, it’s a living lab where innovation, training, and collaboration come together to drive real change for our sector and society.
“Completing Phase 1 of the retrofit of our Innovation Campus has been a complex but rewarding challenge, and I’m incredibly proud of the team, our partners, and contractors who helped bring this vision to life. We’re excited to share the lessons learned and continue supporting the sector with practical solutions for a low carbon future.”
