Double Envelope House: Design And Theory

Design And Theory

In the summer, shading devices eliminate all direct solar gain. Vents are opened at the top of the to exhaust hot air. Fresh air intake uses ambient temperature Earth to cool and dehumidify replacement air at the base.

In winter, the air in the cavity is buffered by warm ambient-temperature Earth under the floor which is partially recharged by the natural convection flow loop during each winter day. In the summer, the convective flow is replaced with cooler near-ambient-temperature Earth replacement air, and the warm air exhausts by natural convection.
