Transforming Truro Vacation Home Reaches Near Zero Energy on Cape Cod

Located on a narrow lot with west-facing views, the Truro Residence  features a multi-functional design that accommodates the home’s various uses. The top floor acts as the “living bar” and includes a long narrow space with a kitchen, living room and a suite. When it is just the couple, this is the only space needed. If more people come, the rest of the top floor can be opened up to provide a dining area and another bedroom and bathroom. When the entire family is visiting, the lower floor, called the “sleeping bar” is opened up, which includes 5 more bedrooms and 3 1/2 bathrooms, plus another living area. Closing this area off reduces energy use for the whole house when it is not needed.
Even though the main views are west-facing, ZeroEnergy Design worked to incorporate solar passive design so as to maximize the energy from the sun in the summer and winter. Large overhangs project the interior from overheating and clerestory windows pull in more daylighting. Geothermal  heating and cooling plus a heat recovery ventilator provides energy-efficient climate comfort, while a 11.7 kW rooftop solar system  provides almost all of the home’s energy. A battery backup system stores enough energy to provide power for the basics if the power goes out. Finishes and furnishings were chosen based on providing healthy indoor air quality and low maintenance. Finally, the area around the home is vegetated with indigenous plants that prevent erosion and don’t require irrigation.
