Save energy and still have excellent indoor air quality.

By using balanced, mechanical ventilation with a high efficiency regenerative heat exchanger it is possible to achieve twice the ventilation rote required by the Norwegian Building Code, and still consume less than half the normal amount of energy. This is the conclusion drawn from extensive measurements made in a Norwegian single Family home last winter. The measurements were made by the EMTEK-programme, which is a Norwegian government programme to promote the introduction of energy efficient products.
