A study of the microclimate in four rooms in historic buildings reveals the different priorities,and, therefore, the different climatic data, needed by museum conservators, compared withpeople studying human welfare. In particular, it is important for conservators to know if a lowpollutant concentration indoors is due to a clean outdoor climate, a low air exchange rate orpollutant absorbent artwork on the interior walls of the building.
Within the framework of the French national research program PRIMEQUAL, measurementsof outdoor and indoor pollution have been carried out in eight schools of La Rochelle (France)and its suburbs. The buildings were naturally ventilated by opening the windows ormechanically ventilated, and showed various air permeabilities. Ozone, nitrogen oxides (NOand NO2), and particles (15 size intervals ranging from 0.3 to 15 m) concentrations werecontinuously monitored indoors and outdoors for two 2-week periods.
We studies the conditions in special old age nursing homes and elderly health care facilities in Japanespecially in a region with a cold climate. A questionnaire survey for all special old age nursing homes and elderly health care facilities in Sapporo and Fukuoka City, and Hokkaido, Saitama, Kanagawa, and Osaka Prefecture, and Tokyo Metropolis was performed. The main questionnaire asks about heating, air-cooling, ventilation systems, sanitary systems and indoor air quality including bio-aerosol and odours.
This paper presents results of an ongoing research conducted at the BEST Polytechnic ofMilan about the correlation between the over time degradation of building envelopcomponents and the indoor climate.
The objective of the present study is to apply and test a mathematical model for thedetermination of the strength of various indoor sources of ultra-fine particles (UFP), and thesink effect for such particles. The model is intended for further development in order to createa tool capable of predicting the concentrations of fine and ultra-fine particles in a room. Inputdata to the model are the ventilation rate, emission rates of ultra-fine particles from differentindoor sources and properties describing sink effects. Laboratory measurements of 10 indoorsources (e.g.
The relationship between indoor and outdoor concentration levels of particles in the absenceand in the presence of indoor sources has been attracting an increasing level of attention.Understanding of the relationship and the mechanisms driving it, as well as the ability toquantify it, are of importance for assessment of source contribution, assessment of humanexposure and for control and management of particles.
In a small case study involving an office room and a laboratory in a building equipped with aHVAC system VOC and particle samples were collected. Both rooms used for theexperiments were newly renovated and low, but measurable amounts of typical indoor VOCand SVOC were present in the air several weeks after finishing of the renovation work. TheVOC concentrations decreased slowly during the test period of 3 weeks.Particulate matter in the room air was characterized regarding the size distribution bySMPS.
The concentrations of ultra fine particles (UFPs) were measured in the medium-size city ofGothenburg, Sweden, in the large city of Copenhagen and at a rural site in Denmark. InGothenburg, field measurements were conducted both in several residential and officebuildings, while in Denmark measurements comprise two office buildings, one of themlocated at a rural site. Concentrations of UFPs were measured simultaneously indoors andoutdoors.
A study on pollutant dispersion and distribution inside public taxi transfer interchanges (TTIs)is reported. The pollutant levels inside TTIs are affected by many factors, for example, taxidata, climatic conditions, human activities and geometrical layout of TTIs. A sitemeasurement of respirable suspended particulate (RSP) level is carried out in a typical TTI inHong Kong. After analysing the effect of the above factors on RSP level, we propose to useartificial neural networks (ANNs) to study such phenomena.
