An integrated system for saving energy and passively collecting solar heat gains in buildings reduces heat loss through glazing both by trapping cold air between glazing and insulating panels or shutters so preventing room air from convecting against the shuttered area of glass, and by admitting fresh air to ventilate the building at the head of glazing and constraining it to flow downwards over the inner glass surface. Sustainable heat is extracted by cooling outgoing stale air to below external temperature with an air to water heat pump. The warm water produced may be circulated through a container serving as a combined hydronic "radiator" and solar panel fitted between two window shutters, the innermost being raised to transfer heat to the room. The outer shutter may be raised to allow the solar panel function of absorbing radiant solar energy towards heating domestic hot water. |
