Designed by Julie Snow Architects it is a wood post and beam structure with a super-insulated floor, roof and walls. The house works with the climatic conditions along the north shore: very cold but sunny winters, temperate long shoulder seasons, and hot summers cooled by lake breezes and cool nights. The house is heated with dual fuel boilers and in-floor hot water heat distribution. During the week the house is kept at a minimum 40º. The design employs passive heating and cooling. The black exterior, south facing glass and the black floor are so effective in passive heating that the house temperature can rise well above 70º on cold sunny winter days, even when the outdoor temperature is -30º, without raising the system’s demand temperature.
