This Artists’ Studio project on the north-fork of Long Island is one of the first projects in the United States to receive international PassiveHouse certification—meeting the rigorous building envelope and energy-use criteria established by the Standard. Each structure is clad in recycled, aged timber that conceals a double-wall insulation system that eliminates thermal bridging from interior to exterior. Windows are also of special construction, utilizing triple glazing and insulated frames to reduce both heat loss and heat gain creating a comfortable, stable, interior environment. Solar panels provide an additional energy-saving measure by offsetting the electrical demands of the structures.
