Discusses use of a gas sensor developed on the Taguchi principle to measure air quality and control the volume of outside air introduced. Presents case studies of a concert hall and a lecture room, and calculates energy saving.

Describes factors affecting condensation: moisture production, ventilation, heating, insulation, and absorbancy.

Discusses problems of condensation in cavity roofs of industrial buildings, including ventilation air as a moisture source. Lists points to watch when foam filling the cavity.

Indoor air pollution is defined, and some of the causes are listed, all of which can be harmful to health. The problem is accentuated by recent insulation measures aimed at economising on energy costs, which lead to a dramatic reduction in natu

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 handbook of constuction techniques for achieving a low air change rate and good insulation in steel buildings. Insulating materials and how to avoid cold bridges are discussed. Air leakage, moisture problems and comfort questions are also considered. Examples are presented of a small industrial building andof a tennis hall.

Outlines the principles of air flow in buildings: the driving forces of wind and thermal pressure; laminar and turbulent flow; and the effects of the building geometry. Reviews the existing mathematical models of air flow and provides worked examples for a house and a multi-storey building.

Describes in detail a mathematical model of multicell air flow in houses. A worked example is given.

A survey of mathematical models of air flow and of ventilation efficiency. Measuring equipment for laboratory experiments is described and the limitations and potential uses of the models are discussed.

Formaldehyde dosimeters have been tested in urea-formaldehyde foam insulated Canadian homes in which formaldehyde levels range from 0.02 to 0.2ppm. Performance of commercial and experimental passive dosimeters was evaluated over 2- to 4- and
