Points out that entertainment clubs, nightclubs, theatres and restaurants, with their highly variable occupation rate, are excellent candidates for demand controlled ventilation. Significant energy savings may be realised by controlling the ventilation of outdoor air to match the heating, cooling and humidity requirements as well as maintaining acceptable indoor air quality. Describes a demand controlled ventilation system installed in an entertainment club in Boise, Idaho, using a multigas indoor air quality sensor sensitive to volatile organic compounds to measure the level of indoor air pollutants which, when combined with a mixed-air temperature sensor to provide economiser cooling, introduces outdoor air at a rate required to adequately ventilate the space.
