OPAL Architecture
Maine architecture and sustainability consulting rooted in Passive House and cold-climate design.
What they're known for
A residential design practice treating climate, landscape, energy modeling, and embodied carbon as one architectural problem.
OPAL Architecture works from Maine’s cold climate outward, using solar orientation, airtight superinsulated envelopes, high-performance glazing, heat-recovery ventilation, and material strategy as design inputs. The firm also provides sustainability consulting using Passive House principles, data-driven energy modeling, and life-cycle analysis. Its early work includes Maine’s first certified Passive House, reflecting a long-running focus on performance rather than a recent sustainability add-on.
