About MGBS
What if we could help contractors and homeowners improve the way they build and restore their homes? What if we could create a green building resource that gives them responsible, environmentally friendly options and useful education about great, sustainable, high performance building products and solutions?
Maine Green Building Supply (MGBS) was founded in 2002 to provide this service.
Steve Konstantino, founder and owner of MGBS, is an expert in building science and renewable energy systems. Originally inspired by super-insulated, passive solar homes he saw and lived in during the early 1980’s, Steve designed and built two passive solar homes himself, often struggling to find healthy building materials and information. Since that time, the building industry has been compelled to respond to the increasing demand for high performance, sustainable products and energy efficient building practices. Founding Maine Green Building Supply was Steve’s way of bringing these types of products to a community of like-minded developers, architects, contractors and homeowners.
Steve is a founding member of the Maine chapter of the US Green Building Council. He is an active member of the Environmental and Energy Technology Council of Maine and also hosts a monthly Building Science Discussion Group and other educational forums.
