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 (formerly Maine Green Building Supply) was founded in 2002 to provide this service.

Our Team


Steve Konstantino

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.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.


Katharine Kranich

Katharine Kranich joined the PBS staff in 2013 after moving from New Haven, Connecticut in search of a more environmentally conscious lifestyle. She is the resident vegetarian and promoter of Jack White Fridays in the office. So far, she is making a smooth transition from stiletto heels to Bean boots.

Katharine earned a Bachelor of Science in International Business and Management from the University of Connecticut. Her professional background is in the design and construction industry, having focused on graphics and marketing for high-profile, energy efficient commercial projects in Connecticut and New York.

She specializes in graphic design, campaign planning, writing and marketing for many facets of the design/build industry. Additionally, Katharine has spearheaded community campaigns for recycling, nutrition, fitness, food drives and a farmers market in New Haven.

Living and working in Portland, Katharine is actively involved in the building science and creative communities. Outside of PBS, she provides pro bono and project-based design and marketing services to local small businesses, non-profits and start-ups.  A long-time passion for ballet drives her love of yoga, and she enjoys throwing dinner parties for her carnivore friends and hiking the mountains of Western Maine.


Alba Briggs

Raised in a forest on the coast in eastern Maine, Alba Briggs has a close connection to the various forces of nature.  During this time, he developed some carpentry skills and got a chance to work on several houses, old and new.  In high school Alba worked with his father to construct a double stud wall inside an old post and beam from 1787.

Alba received a Bachelor’s degree in Media Studies, with a focus on video and graphic design. During this time, he decided to discover the United States for himself – on a 9000 mile hitch-hiking adventure around the country.  With any luck, his journals are soon to be published.

Working at a hardware store in college, he learned about many materials and installation procedures.  Now at Performance Building Supply, Alba enjoys studying the latest building technology from Europe, and adapting it to the needs of contractors and architects here in the States.

When not working, Alba enjoys art, chess, history, wilderness survival, primitive building techniques, and learning everything there is to know about how to stay warm and dry.


Catherine Weiland

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.

Ben McCrave

Ben McCrave grew up in the Mt. Washington Valley and learned the value of nature early through hiking, skiing, and exploring. He also learned the value of a warm home during the long cold winters.

In between his academic years at St. Lawrence University, where he received a bachelor’s degree in Francophone Studies (French), Ben spent his summers working for the Appalachian Mountain Club in their high huts. In these huts Ben learned what it takes to run a facility completely off the grid in extreme conditions. Energy conservation became a daily challenge when the sun didn’t shine. This experience, in combination with his recent completion of the Appalachian Trail has given Ben an understanding of the value of conservation and of a well-built shelter.
