For that study , three german buildings with double facades have been monitored for at least one year in order to evaluate their energetic performance. The first building had no air conditioning facilities, the second one had cooling equipment without mechanical ventilation, and the third one had cooling equipment combined with mechanical ventilation.
The simulation of airflow pattern in an office building in Singapore is based on the environmental conditions and the corresponding ventilation parmeters measured on a typical day. The findings of that study are reported in this paper.
The aim of this study is to clarify the effects of indoor environmental characteristics of hybrid - natural and mechanical - air conditioning systems in office buildings during intermediate seasons. The other objective was to obtain design data.
Multi-storey buildings with double-skin facade are not numerous and there is little experience of their behaviour in operation.In this study the authors analyze the impact of the double-skin orientation, the impact of the wind orientation, and the degree of wind protection on the facades. Simulations were realized too.
Endotoxin is one of the most powerful inflammatory mediators known. This explains the high prevalence of respiratory disorders among smokers.In this study, GC-MSMS Gas chromatography-mass spectrometry is used to analyze the presence of endotoxin in smoke from active smoking and in environmental tobacco smoke.
This paper describes characteristics of statistical distributions for concentrations of 17 VOCs and 11 aldehydes in homes in Japan. First a probability model was applied to the occupant's simultaneous exposure to the mixtures in homes, then joint probability distributions of 28 organic compounds were generated from the best-fitted distributions of individual compounds.
That research is based on the assumption that there are differences among normal subjects as to their vulnerability to stress-related symptoms to health/illnessThe study aims at increasing the understanding of SBS complaints in relation to personality factors.A relationship between personality characteristics and health-related behaviors, and between personality characteristics and perceived health is demonstrated.
The author asserts that to maintain a good indoor air quality, both ventilation and reduction of the pollutants sources are necessary. Standard 62.2 defines the minimum requirements about ventilation for an acceptable indoor air quality, but does not deal directly with the sources of pollutants. So the author gives an inventory of the main indoor air pollutants and how to cope with them. He maintains that the treatment of the pollutants at their source is very often the best way to keep a good indoor air quality.
