That study proposes an Express Assessment Protocol (EAP) to quantify IAQ problems by assessing the "dominant" contributors to unacceptable IAQ. That EAP could be a useful tool for policymakers, building owners and professionals to quantify IAQ problems in offices and to make improved decisions.

The installation of upper-room ultraviolet germicidal irradiation (UVGI) devices in ventilated rooms can reduce the transmission of infections by an airborne route. That study investigates the relationships between the lamp location, the lamp power, ventilation power and room heating in a small ventilated room. The results are presented.

To investigate the effect of the headroom on de displacement ventilation (DV) system, a numerical simulation applying a validated CFD model was used. The simulation and comparison of two different headroom heights in a space was carried out. The results are presented.

The ventilation system of an operating theatre in an hospital minimises the risk of airborne infection. In this paper, the integrated effect of medical lamp position and diffuser discharge velocity on ultra-clean ventilation performance in an operating theatre is reported. Their use appears to slightly affect the thermal comfort environment , but it can have a serious effect on the movement of infectious particles that can increase the cross infection rislk.

The roles of CFD in building design are presented in this paper such as designing a thermally comfortable, healthy and energy-efficient building. The developing trends in applying CFD to building design are analyzed by reviewing the literature. in all the proceedings of the International Conference on Building simulation.

Results of 3 years of measurements in the chemistry department building of the university of Athens are summed up in this paper. Levels of CO, CO2, SO2, NO2, Cl2, HCHO, O3 and TVOC werre measured in laboratories, classrooms and offices. A questionnaire survey was conducted too concerning working conditions and perception of IAQ. Results and comments are presented.

The aim of the European project HOPE (Health Optimisation Protocol for Energy-efficient buildings) is to demonstrate the energy-efficient buildings can be healthy and comfortable too for their occupants. Measurements were carried out to evaluate indoor environmental quality. And questionnaires were filled by the occupants. In U.K.

The aim of that study was to pinpoint indoor environmental variables necessary for providing an assessment of the condition of indoor environment in homes . Data from three existing housing and health studies were used to conduct a component analysis. 14 components have been selected to form the basis for an indoor assessment to be used in environmental studies.

The study of the particle pollution in an office under two different ventilation modes is presented in this paper. The concept of perceived particle intensity has been applied to evaluate the particle pollution from copiers under mixing ventilation and displacement ventilation. For the particle concentration distribution , measurements of the different sizes of particles and a numerical simulation have been made. The results are presented.

A comparison is made of the performances of various heating, ventilation and air conditioning (HVAC) arrangements in eliminating pollutants in working environmemnts in Taiwan. The airflow of various simulation routes are evaluated. Simulation results are used to identify the vent arrangements for a ventilation efficiency.
