ENERGY EFFICIENT BUILDING ENVIRONMENTAL CONTROL APPARATUS AND METHOD

摘要

A building includes exterior walls that form spaces which are selectively vented under control of a control system. Vents are operated to retain trapped air or exhaust trapped air to improve the energy performance of the building. Vents with selectively operable dampers may be located proximate a top of a wall or wall section of wall. Vents may also be located proximate a bottom of a wall or wall section to allow drainage of liquid and circulation of air. Various specific wall constructions provide for an air gap between layers of exterior sheathing of the exterior wall. The air gap may be in addition to a space between interior and exterior sheathing, which space may include a thermal insulation material (e.g., fiberglass batting).
