Herrontown Builders, the builder of Princeton’s most finely crafted homes for more than 25 years, is at the leading edge of a movement committed to building environmentally responsible homes, designed to benefit its homeowners with significant energy and water cost savings and better indoor environmental quality. The builder’s high performance homes, which far exceed Energy Star requirements, actually save their homeowners an estimated 48% in annual utility costs when compared to comparably-sized new homes from other builders.
