The double-glazed external wall (double-skin) system is an effective passive technique that candecrease solar heat gain into the building. Detailed information concerning the thermal characteristicsof the double skin is necessary to accomplish a good design for thermal comfort and energy-saving.In this paper, the 3-dimensional thermal characteristics of the double skin that had the openingspartially installed and was partially shaded by the adjacent building were investigated by a fieldmeasurement.

We developed an air cleaner (AC) for chemical sensitivity (CS) patients. The AC have a high efficiencyair filter and a special activated carbon filter to remove airborne particles and gaseous contaminants.Using the AC, we conducted a monitoring experiment to investigate improvement of indoor air quality(IAQ) in the actual residences of CS patients. In the experiment, IAQ in the residences of nine CSpatients was measured before and after AC operation.

The gas cooking device and the induction heating (IH) cooking heater is used for cooking. Weexamined a difference of diffusion characteristics of odor emitted at the gas cooking device and the IHcooking heater. The IH cooking heater has the advantage that it does not give out carbon dioxide (CO2)from burning during cooking. We evaluated deodorization efficiency of a new system which wasdeveloped to purify air pollution gas generated during cooking without using an exhaust air duct.

This report describes the results from the questionnaire and detailed survey conducted in 2004 to 2006.The 15 items of questionnaire included in facilities management, maintenance management, savingenergy, art gallery facilities. The number of art galleries investigated by questionnaire survey is about171 art galleries in Japan. Then we scanned findings during about 1 year 6 months to get speculationhaving high reliability and summarized a tendency and a characteristic based on the result. Fromthesurvey results, it shows the tendency and characteristics about each item.

Urban indoor air quality (IAQ) is an international health issue, since city dwellers spend 90% of theirtime indoors. Research by a number of authors is reviewed here, demonstrating a range of capacitiesof indoor plants to improve IAQ and promote occupant wellbeing. Our laboratory studies, with nineindoor plant species, and our field studies in 60 offices, show that potted-plants can reliably reducetotal volatile organic compound (TVOC) loads, a major class of indoor pollutants, by 75%, to below100 ppb. They work equally well with or without air-conditioning, and in light or dark.

In Thailand, the emissions of air pollutants from industrial areas are one of the main sources of airpollution. It is generally believed that indoor air pollution such as VOCs as negative causes for ahealth risk. In our research, we measured the concentration of two Volatile organic compounds,formaldehyde and isopropyl alcohol, emissions from sheet-fed offset lithographic printingoperations during January - July 2006 in Bangkok, Thailand. The portable ambient air analyzer wereused to collect and analyze formaldehyde and isopropyl alcohol concentration.

Personalized Ventilation (PV) has been shown to improve inhaled air quality recently. However, it maylead to dissatisfaction such as draft due to personalized air applied locally to the facial region, orstuffiness due to inadequate air supply. This study aims to identify some reasons for the dissatisfactionamong tropically acclimatized people through a systematically experimental design.In this study 24 subjects were subjected to a series of random facial exposure to local air movementeach of 15 minutes duration in a well-controlled indoor air quality chamber.

A floor heating, so called ‘Ondol’, is widely used in korea, and it has been known that Ondol provids good thermal environment. [1] However, the impact sound through floor is great and ventilation rate depends on infiltration in rooms where the Ondol is a

In the sickroom, high indoor air quality and thermal comfort is essential for the treatment of patients.Therefore it is proposed to use displacement ventilation for the whole room ventilation and the radiantpanel for the thermal comfort of each bed. This study is intended to investigate validity of this system.This paper shows the experimental and calculated results of the displacement-ventilated room with onebed and one radiant panel. The vertical profile of contaminant concentration and temperature aremeasured and compared with the calculated ones.

The epidemiological research on indoor environments in homes and health has been reviewed.Science has mainly been about health effects like asthma/allergies and exposures such as VOCs,mould and dampness. So far there are few conclusive findings. Dampness, pets, mites, dampness,ETS, a low ventilation rate, and some phthalates are risk factors for asthma and allergies. There is alarge need of studies of other health effects, and other exposures, especially regarding new frequentlyused chemicals.
