Living in a house whose oldest section dates from 1789, Jim Liao felt there was a lot of unnecessary waste of energy and expenses. Having lent his support and expertise to help Energize NY get off the ground, Jim knew exactly where he could get help to improve the energy efficiency of his colonial. He began by selecting Healthy Home, an Energize Comfort Corps and Home Performance with ENERGY STAR program contractor. Healthy Home identified his 18th century colonial’s unique problems through a comprehensive home energy evaluation. To his surprise, the evaluation showed that the older section of the house was more efficient than the addition he built in 2001. Jim chose to air seal and insulate his home from top to bottom. This measure would block cold outside air from being drawn into the house around the sill and basement, and heated air from escaping through the attic and roof. Jim is very pleased with his home upgrades and could not be happier with the results. His home is now wasting much less energy and his heating costs have dropped significantly too.
