Points out that increased thermal insulation and draughtproofing of homes can increase the risk to health of indoor air pollution. Includes condensation as a pollutant along with associated mould growth. Notes collaboration by Pilkington the glass company and the Timber Research and Development Association plus Laing the housebuilding group, to combat condensation by passive ventilation. Treats sources of indoor air pollution - formaldehyde, asbestos, gas appliances, tobacco smoke, thoron, radon.

Measurements of the levels of nitric oxide and nitrogen dioxide emitted by radiant and convective space heaters revealed that the NOx emitted by the former was mainly NO2 while convective heaters produced mostly NO. As the air became vitiated, however, the convective heaters began to produce more NO2than NO. This evidence confirms that the nature of the NOx produced by a nunflued room heater depends on the type of heater and the conditions under which it operates.

Summarises measured data on energy savings from conservation retrofits in existing residential buildings, covering approximately 115 retrofit projects in four general catagories: utility-sponsored conservation programmes;low-income weatheriza

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.

Describe tests carried out in an 850-seat auditorium of 4000 m3 to compare the readings of a CO2 indicator for controlling the ventilation air flow with the readings from a Stafa odour indicator. Supplies the results in diagrams and tables and discusses them. Notes the odour indication agrees well with the CO2 indication until a certain point when the CO2 concentration is decreasing. Notes this need not be a drawback.

Describes how multizone tracer gas analysis techniques can provide a complete description of office ventilation. Treats the concept of ventilation effectiveness to characterise internal air distribution. Discusses the measurement of whole building ventilation rates and ventilation effectiveness in mechanically ventilated office buildings.

Describes experiments carried out by the Danish Maritime Institute using data from the Aylesbury experiments of the UK Building Research Establishment. The simulation of the standard rural terrain and the Aylesbury terrain was achieved by mea

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.
