Frequently asked in New Hampshire
What defines a healthy, efficient New Hampshire 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 cold, snowy winters with heavy freeze-thaw cycles and a short building season.
How resilient does a New Hampshire home need to be?
Detail for shoreland water quality protection act setbacks and impervious surface caps near lakes and for the region's climate exposure. In New Hampshire, 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.
