Frequently asked in Maine
What defines a healthy, efficient Maine home?
Continuous air barrier, verified low leakage, mechanical ventilation with heat or energy recovery, filtered fresh air, low-emission finishes, and a right-sized heat pump system tuned to the long, cold winters on the coast with salt air, wind exposure and short summer building windows.
How resilient does a Maine home need to be?
Detail for shoreland zoning setbacks and clearing limits under maine dep rules and for the region's climate exposure. In Maine, back-up power, water management and envelope durability pay back within a decade.
What certifications are worth pursuing?
ENERGY STAR and DOE Zero Energy Ready Home are pragmatic starting points; Passive House and LEED are stronger commitments and change the design earlier.
