Within the European research project HOPE, office and residential buildings were investigated using checklists addressing the building characteristics . the occupants were asked to fulfill questionnaires about their perceived comfort (thermal visual, acoustical and IAQ) and health (SBS and allergies).
The collected data are compared looking for correlations between building characteristics on one hand, and perceived comfort and health on the other hand.

The aim of the study was to investigate the association between ventilation and the worker’s nonspecific building-related symptoms (BRS) in one office. The study office took place in the sixth floor of one semiconductor company with a floor area of 1452 m

A field study in 18 selected houses in Dublin and the surrounding area has been carried out between September 2004 and February 2005Continuous measurements of Indoor temperature, relative humidity (RH), concentrations of selected pollutants including carbon dioxide (CO2), carbon monoxide (CO), particulate matters (PM1, PM2.5, PM7 and PM10), moisture, and ozone (O3) were made in each house. The infiltration rates in ten houses were tested with both fan pressurization and tracer gas decay methods. The results of those investigations are presented.

This study deals with the indoor air quality in five mechanically ventilated and four naturally ventilated open-plan office buildings in Copenhagen along with their occupants satisfaction. A simplified assessment procedure has been used for that study..
The results indicate that occupants in naturally ventilated offices have a lower prevalence of symptoms and are more satisfied than those in mechanically ventilated offices

In this study, personal displacement ventilation (PDV), including two cases with all seats taken and two middle seats taken, is compared with overall displacement ventilation (ODV) of all seats taken under the condition that supply temperature is 24C and air change rate is 60 l/s per workstation. The results indicate that PDV can be used in the room with big change of occupants number to satisfy the need of thermal comfort and air quality. When not all seats are taken, designers should increase supply air requirement or reduce its temperature for thermal comfort.

The aim of that study was to clarify the differences in airflow characteristics outside and at three points in a cross-ventilated room under six opening conditions: window-open; insect-screen; lace-curtain; fabric-curtain; combined condition with insect-screen and lace-curtain; and combined condition with insect-screen, lace-curtain and fabric-curtain. The air velocity was measured by four ultrasonic anemometers, during the summer of 2004. The results obtained are presented.

For that study, an investigation of indoor air microbes of two Hong Kong Old Folks Home, one with naturally ventilation and another with mechanically ventilation device, was carried out. Samples of airborne fungi and bacteria were taken from five indoor sites characterized by different human activities along with an outdoor sample for comparisonBoth bacterial counts and fungal counts in air in the naturally ventilated Home were higher than that in the mechanically ventilated Home.

The paper deals with a nation wide field study in dwellings in order to assess household exposure to indoor air pollutants and related risk factors. It has been launched by the Observatory on Indoor Air Quality (OIAQ) . About 700 dwellings were randomly selected for investigation on the main indoor air pollutants.
An information system for indoor air quality field studies, designed for surveyors, laboratories, and project coordinators, has been developed by the CSTB in order to manage the 10 millions records of the whole campaign.

Ventilation airflow rate of the occupied houses in the northern region of Japan is the subject of that study. The investigation consisted in the measurement of the ventilation rate using three different methods : the constant concentration method, airflow measurement at inlet/outlet and PFT method.
This paper presents the results of the constant concentration method, obtained with a B&K 1302 multi gas monitor and two B&K 1303 multipoint samplers and dosers., An example for the improvement of the ventilation by increasing the ventilation rate is also presented.
