Indoor concentrations of a variety of particulate matter and gaseous compounds often exceed outdoor concentrations. We should examine exposures to air pollutants within the important built environments or perhaps on a personal basis. The development of reliable biological markers is still an area of active research. Instruments passively monitoring NO2 exposures over timeperiods ranging from hours to days have been used in several studies in theU.S.
Contains further papers, reports and conference summaries from the 3rd International Conference on Indoor Air Quality and Climate, 1984, as well as afull list of authors and titles of papers printed in this and the previous volumes.
R-2000 Homes have specific requirements for mechanical ventilation, usually incorporating heat recovery ventilators. Performance testing was carried out on 12 residential heat recovery ventilators in 1984, representing the range of equipment
Approximately 40% of the energy consumption in Sweden is utilized in the heating of buildings. In order to reduce the amount of energy utilized for heating purposes, more stringent thermal insulation requirements for buildings were introduced.
Radon in indoor air is discussed in the perspective of the effective dose equivalents from other sources of radiation. Estimates of equivalents from indoor radon and its contribution to lung cancer incidence are reviewed. Swedish experiences with cost effective remedial actions in a cost-benefit perspective.
This report details the development and field testing of a passive sampler system to collect gaseous and particulate contaminants in indoor air and the evaluation of the collected materials for biological effects using a simple bioassay system. The passive sampler-biossay system is a cost-effective objective method for determining indoor air quality.
Describes measurements undertaken at the Fraunhofer-Institute fur Bauphysik of the effects of various mean and turbulent air flows under constant air temperature, indoor surface temperature, and humidity, using an anemometer and Laser Differential Interferometer.
This paper describes the numerical analysis of room air distribution by the finite element method which can easily deal with any domain, the boundary conditions and so on.
Discusses the current standards regarding indoor climate produced by ASHRAE, ISO and NKB. The parameters effecting thermal comfort and air quality are outlined.
The paper presents the results of the experiments accomplished in the Microclimatic Laboratory of the Hungarian Institute for Building Science on the problems of the discomfort feeling caused by draught phenomena.
