An optimistic view of housing in the future is that all homes will be built to require minimal energy to operate and to be healthy living environments. One example is the Pure House in Westport, Connecticut. Built using a prefabricated, high-efficiency panel system, it meets the criteria. Although the builders opted not to have the house certified, it follows the concepts and engineering requirements of the rigid Passive House standards, first developed in Germany.
The house is equipped with four zoned high-efficiency heat pumps, the main source of heating and cooling. People sometimes are skeptical that these heat pumps are sufficient for cold New England climates, but because the house was built with such a tight thermal envelope, a more elaborate heating and cooling system was not required. All insulation in the house is thicker than required by Connecticut building codes.
To minimize the need for electricity, the house is equipped with LED lights, which use far less energy, and Energy Star-rated appliances. The house even has a charging station for an electric car.
American-made products were used throughout the construction, including high-performance, triple-pane windows and doors, as well as sustainable materials such as EcoTimber, a type of engineered wood flooring. The materials sourced for the construction and interior design were chosen for their healthy, non-toxic composition. As an example, the kitchen and bathroom fixtures by Grohe are all lead-free. All the paint, stains, glues and other materials used in the construction are as non-toxic as possible, to maintain a healthy environment inside the house. A heat recovery ventilator exchanges the stale interior air with the outside fresh air continuously through the day and night. The landscape is designed for zero runoff and the native planting requires no irrigation system or fertilization.
“What I like most about building Pure Houses is the incredible air quality. Breathing fresh air all the time, that is what it’s about” says Doug Mcdonald, founder of the Pure House. Although, Mcdonald admits there is a small up-charge (approximately 10%) for building such an efficient house, he also conveys the long-term savings in energy costs. He says his houses use about 90% less energy than the conventional houses in the area.
Mcdonald says the Pure House “is born from the same model that brought you restaurants that serve ‘farm-to-table’ food and the reason why you shop at your local farmers market. You want to know that the ingredients are pure and natural and good for you.”
