Reduced ventilation and infiltration, and new materials and machines have increased levels of indoor contaminants. Investigations of many indoor environments reveal contaminant levels above those set as standards for the workplace environments. The acute and chronic health effects on the population are not well known. This paper discusses the current general status of the research in the USA and the planned future effort. Worldwide research is also summarized and future directions are suggested.
This paper reviews the work carried out in the Netherlands on moisture problems. In current air flow simulation models for buildings, moisture transfer and diffusion in and between rooms are not taken into account. The aim of the research project is the development of an integral hygrothermal model in which the above mentioned aspects are incorporated.
Summarizes a study reviewing indoor air pollution in housing in Canada. Concludes that 1, many materials and conditions which contribute significantly to indoor air pollution are known to be present in Canadian houses, 2,individual susceptibility to air pollution varies, 3, smoking remains a major source of pollution, 4, some energy conservation measures aggravate indoor pollution problems, 5, the full health, social and economic costs have yet tobe determined, and 6, acceptable levels of effects on health have not been defined.
The levels reported in diverse publications of by products of cigarette combustion (acrolein, aldehydes, aromatic hydrocarbons, carbon monoxide, nicotine, nitrogen oxides, nitrosamines, particulates, and others for which scattered information is available - HCN, ketones, nitriles) are summarized in tabular form. Summaries also include information on test conditions such as ventilation, size and types of premises, monitoring conditions, number of smokers, and rate of smoking.
Reviews the papers on air infiltration and ventilation research presented at the ASHRAE annual meeting held in Honolulu, Hawaii, in June 1985. The twelve most significant papers on multizone infiltration and air leakage are discussed at length and other infiltration-related papers mentioned. Authors' abstracts for the twelve symposium papers plus seven technical papers are presented.
Evaluates the space-conditioning energy conservation potentials of landscapes designed to ameliorate building microclimates. The physical bases for vegetative modifications of climate are discussed, and results of past study of the effects of vegetation on space-conditioning energy consumption in buildings are reviewed. The state-of-the-art of energy-conserving landscape designs is assessed and recommendations are presented for further research. Landscaping mobile houses and single family dwellings is considered.
Describes the different types of monitoring and sampling techniques that can determine the radiation burden of the general public from radon and its decay products. This is accomplished by measuring the range and distribution of radon and rad
Presents a review of the main methods used for the study of air movement. Includes sections on physical modelling (wind tunnel modelling etc), analogue (water and electrical) models of air movement, mathematical models and digital computer analogues, and full scale investigations including pressurization andtracer gas techniques.
