The new centre will include a display facility, warehouse and offices allowing Cernunnos to advise, install and design renewable technologies for local residents and businesses.
Based in a conservation area, the centre is housed in a Grade II listed barn dating back to the 17th century.
Peter McKeown, director of operations, said: “The space and the heritage of the property was simply breath-taking, however it had been empty for some time. We wanted to bring the property back to life using the latest renewable technologies and sustainable interiors and be an example of best practice.
“We look forward to establishing a strong relationship with the community, increasing our business, employment for the community and providing a vision of sustainability that everyone can benefit from.”
Cernunnos together with Cambridge Carbon Foot Print will be running educational workshops and showcasing their retrofit homes during September.
