The mitigation to reduce indoor pollutant concentration are increasing ventilation rate or to reduce the emission of the pollutant which is also common in VOCs. Households, furnitures, building materials and so are well known as the source of indoor VOCs. There are several devices to measure emission of VOCs, such as an emission chamber or FLEC, which are adopted in ISO 16000. However these 2 methods has each disadvantages e.g. the chamber is suitable only in a fixed condition such as a laboratory, or the necessity of a pump and humidifer.

The use of hypochlorite for water disinfection is source of chloramines production, which are transferred to the atmosphere.Nitrogen trichloride (NCl3) is the main component, which is a major cause of respiratory and ocular problems for swimmers and lifeguards. This first part comprised a sampling campaign concerning the measurement of NCl3 in a swimming pool (Picardie-France) during 15 days (October 2001). This campaign concerned the air quality diagnostics and showed that the majority of detected levels were critical (P50 = 0,44 mg/m 3 ).

This work, along with the experimental measurements on which it is based, was carried out in the framework of research undertaken by the French “Groupe de Pilotage sur la Qualité des Ambiances” (GPQA), whose task was to initiate and co-ordinate work on ai

Measurements of wind speed and wind direction, air temperature inside and outside an urbancanyon also infrared radiation in buildings have been measured on summer 2001 in Athens, in fivedifferent urban canyons, in the frame of Urbvent project. Urban canyons with different geometricalcharacteristics and orientation were placed in five different neighborhoods in Athens.Measurements took place in four different height levels inside each canyon, in the facades ofthem, also in the top of each canyon.

The main goal of the present study was to determine thermal comfort parameters for dwellers of low-cost houses for a given set of indoor environmental conditions. 112 people living in over 60 dwellings were interviewed, according to a comfort questionnaire where information regarding age, sex, clothing, level of activity, thermal sensation and preference of the subjects was collected. Environmental factors such as air temperature and humidity were simultaneously registered with T/RH data-loggers. Results were then analyzed by comparing subjective and environmental factors.

Noise measurements were made at 10 locations in ‘canyon’ streets in Athens with aspect ratio (height/width) varying from 3:1 to 1:1. The main purpose of the measurements was to examine the vertical variation in noise in the canyons to indicate the natural

It is well understood that there are many sick professional buildings in use all over the world. Most of them are sited in or near the center of large cities where the ambient atmospheric conditions are not good. The sickness syndrome of those buildings combines both the indoor air quality and the local comfort regime. In many cases the responsibility for the formation of these syndromes lies with the not appropriate envelope design and the misuse of the building by the inhabitants.

This study investigates the behavior of vapor in a ventilated room in which vapor is being produced. A test chamber equipped with three types of ventilation ducts and a vessel filled with heated water for evaporation was analyzed both experimentally and numerically. Experimental results showed that temperature and moisture distributions differed depending on the ventilation types. A numerical model of vapor generation from the heated water was introduced to simulate the evaporation.

The Solar-Campus Juelich consists of two buildings, as part of the University of Applied Sciences, Aachen, and student dormitories for 136 students (5 row houses), see Figure 1. In a general agreement, the overall energy demand for space heating of all buildings was limited to 40 kWh/m 2 a, which is less than 50% of the existing German national regulation (Wrmeschutzverordnung 1995). Extra costs were provided through the AG Solar of the German state North-Rhine-Westfalia.

This study included the IAQ survey concentrated on particle levels in the library store (area of 1000 m 2 and having books or journals over 100 000 pieces in total) at the basement. The store was divided into three sections covered with plastic walls. Each section was cleaned with three different methods: two vacuum cleaners equipped either by HEPA filters I or II and one cleaner equipped with a water filtration unit. In addition, the surfaces of all sections were swept by wet cloth after twelve hours of vacuum cleaning.
