ANDREW Seller, director of sales and special projects at Aspect Windows in Exeter, has become a certified Passivhaus design consultant after completing a course on ultra-low energy buildings.
His exam success means the company, based in Trade City, off Sidmouth Road, is thought to be the only windows company in Devon to offer a Passivhaus energy efficient design service.
Andrew said: "I can't wait to get started. We're already firmly committed to energy-saving products, and this is another string to our bow."
Managing director Steve Cooling added: "We are extremely proud of Andrew's achievement and are thrilled that Aspect Windows can now offer the full Passivhaus design service.
"This is the start of a new chapter for the company."
Aspect Windows is currently in the process of refurbishing its showroom in Apple Lane. The family-run business has been trading since 1981.
