| Abstract | A house needs a third of its air exchanged every hour. Owners of houses built before 1960 relied on air leakage through the building envelope for indoor/outdoor air exchanges. And they could, because houses then were leaky enough and wind or temperature difference saw to the necessary air movement. In the 1960s, houses became more airtight, and some were heated electrically (they did not even need a chimney). In the 1970s with its oil crisis, houses became even more airtight. With little air leakage through the building envelope, a mechanical ventilation system is required for moisture and pollutant removal. So, the question now is: how does one ventilate optimally? |
