Ecohomes utilizes in-depth knowledge of building science to help homeowners navigate the tricky waters of energy efficiency. With a home-energy evaluation, a crack team of certified advisers will inspect, test, safety-check, and evaluate the components of each house to find ways to increase comfort and reduce utility bills. Applying scientific principles and using sophisticated diagnostics, advisers treat the house as an integrated system, not as a grotesque Frankenhouse of separate, mismatched air-conditioning units, windows, and a weird, lurching gait. The advisers will provide a list of options and costs for an all-in-one solution that takes care of permits and construction. Homeowners are under no obligation to pursue the recommendations, though potential home-energy reduction averages 30%–50%.
