Houses without heating systems - in real life.

Describes low energy houses which have been built at Lindas in Sweden. A traditional heating system has been replaced in the design by heat exchanger in combination with an exceptionally well insulated construction. The terraced houses maximise use of passive solar gains, while balconies and projecting eaves protect against excessive solar radiation during the summer. External walls are exceptionally well insulated and airtight. The ventilation system consists of a supply and exhaust air unit with a counter flow heat exchanger that provides 85% heat recovery. In the summer the heat exchanger can be turned off and the house ventilated with only exhaust air and open windows. Occupant control is simply a matter of common sense - windows are kept closed when it's cold outside, and blinds or awnings are lowered on the southerly windows when it is hot.
