A total of 200 experiments on evaluation of body odour were performed in two identical auditoria at the Technical University of Denmark at ventilation rates of 0.4-26 l/s/person, with an air space per occupant of 4-21 m3 and with air temperatures of 17-26 deg C. Ten minutes before the end of each 35 minute lecture period 10 judges entered the space and were questioned concerning their acceptance of body odour. They were also asked to evaluate the odour intensity on a fixed scale.

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.

Sixty five houses in Ontario, Canada, were air tightened with the aid of fan depressurization. The average percentage reduction equivalent leakage area for all houses was 36%. An improvement in comfort was noted. No significant changes occurred in the overall number of moisture problems but there was a definite change in the type of problem. The net fuel reduction for the total sample was 4.8%.

Radon-222 and 222Rn progeny concentrations, barometric pressure and pressure differentials between inside and outside were measured continuously in the basement of a recently constructed energy-efficient house in metropolitan Denver, Colorado

This paper reviews the most recent research on wind loads on low-rise buildings. Novel measurement techniques and methodologies are reviewed, and selected experimental results from various studies are presented. Particular emphasis is given to works aimed at the formulation of codified data, ie,results appropriate for incorporation into design standards and codes of practice. Only either full-scale studies or those done under conditions simulating the earth's atmospheric boundary layer have been considered. Comparisons between full-scale and laboratory results are discussed.

The thermal effects of air flows in building structures have been analyzed by computer simulation. Some laboratory experiments have also been carried out concerning natural convection in closed and semi-open cavities filled with fibrous insulating material. Three different flow systems in building structures have been studied: natural/forced convection in open/semi-open (permeable cold surface) 2-dimensional insulation structures, heating of infiltrating air in cracks and diffusive infiltration.

A method to analyze thermal and moisture physical behaviour of building components under transient conditions is introduced. The method is supported by the procedure TRATMO (Transient Analysis of Thermal and Moisture Physical Behaviour of Constr

A method has been introduced for the analysis of the hygrothermal behaviour of building materials and construction. The model equations for coupled heat and mass transfer used in the computer code TRATMO and in the determination of hygrotherm

A transient simulation method TRATMO with applications to the analysis of the hygrothermal behaviour of timber frame constructions with additional thermal insulation is discussed. This method makes it possible to evaluate the hygrothermal behaviour with respect to risks of mouldering since it gives simultaneous information on moisture content and temperature at certain sections of the construction. Based on the computer simulations and experiments a number of practical aspects to be considered in additional thermal insulation of timber frame constructions are introduced.

This paper discusses the thermal effects of air flows, and some aspects of the influence of moisture and moisture transfer on the thermal performance of a structure. Mathematical and physical modelling of simultaneous coupled heat and mass transfer in porous materials based on the volume averaging technique has been used to analyze these phenomena.
