Ventilation and infiltration rates were measured in eight office buildings using an automated tracer-gas measurement system. The buildings range in size from a two-story building with a floor area of about 2000 m2 to a 15-story office building.
Describes the measurement of infiltration in each of the seven rooms of a house over the period from November 1983 to January 1984 with occasional use of mechanical exhaust ventilation. Nitrous oxide was used as the tracer gas. External meteorological conditions were also recorded. The measurement principles are outlined and detailed results presented. Various mathematical models are assessed in comparison with the measured data.
A test chamber was designed and constructed at Princeton University for research purposes. The structure is essentially a miniature house, with no internal partitions, built with simplicity and uniformity in mind. Also thetest chamber was built to have minimal infiltration rates, and with versatility to facilitate experimentation. The test chamber is a tool to study subtle effects in the thermal performance of structures.
Covers the factors affecting air infiltration and indoor air quality, the utility of existing air infiltration models, and the ideal and practical requirements of a relevant indoor air quality model that could be used as a tool for management of atmosphere in tightly enclosed residential spaces.
