About Performance Building Supply

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?

Performance Building Supply was founded in 2002 to provide this service.

Steve Konstantino, founder and owner of Performance Building Supply, 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. He hosts a monthly Building Science Discussion Group and other educational forums.

Catherine Weiland is our design partner and the Principal of balance design studio.  Through Catherine, we offer interior design services  including kitchen and bath design.  Catherine’s green journey began with having children.  “Eating for two caused me to pay more attention to what was in my food which led to paying  more attention to what was in a lot of things.  That cascaded into a broader exploration of health, sustainability,  and social  responsibility to help define what I wanted to model for my kids.”

Catherine and her husband renovated distressed properties  while raising their young family.  After their children entered school, Catherine decided not to return to her previous corporate career and instead chose to do what she really loved – making people’s worlds more beautiful.  In her words, “Like me, the folks who seek out Performance Building Supply are on a journey.  The word ‘green’ may conjure up different things, but each person is trying to live in a way that aligns with their values.  As their awareness of that grows, their journey evolves.  My job is to deliver the right blend of form, function, splurge, restraint, ideals, and practicalities that meets them where they are and supports them where they are going.  If I do this well, they feel as good about themselves as they do their space.  And that…is beautiful.“ Check out balance design studio’s Facebook page for Catherine’s insightful  views on design.  Her work has been featured on Houzz, on Designer Home Tours, and in  Maine Home + Design.

Catherine has her MBA with honors  from Boston University and when not designing  she enjoys family walks, reading, and volunteering.
