Abstract
In the last decade, construction practice has evolved in response to the need for reducing air leakage through the envelopes of houses. As a result, new houses have been built more nearly airtight on average. In recognition of this fact, the 1990 National Building Code (NBC) requires a mechanical ventilation system capable of producing 0.3 air changes per hour, thereby providing a mechanical means of achieving minimum levels of ventilation when needed. With only a few regional exceptions, builders have been meeting the intent of the mechanical ventilation provisions of the NBC with exhaust-only fans-typically kitchen and bathroom fan combinations.
