After describing smoke hazards, this document gives for the designers the basic principles of smoke management in atriums. Requirements of the Canadian building code are also described.

Comments about the project of the new french standard NF S 90-351 "Clean rooms and related controlled environments in medical establishments" and the consequences on the design approach of clean rooms to master airborne contamination are given.

The french standard NF S 90-351 has been modified to include a wider field of application. This standard now takes into account previsional aspects. It is needed to define "areas at risk", and materials and equipment performances.

In this paper, the variations of the airflow induced by a moving operator in a cleanroom installed with a curtain, are studied numerically. The effects of the moving operator and curtain on the airflow patterns are taken into account.

After a review of CFD models and a simplified (zonal) models predictions, a simplified procedure, based on charts and non dimensional groups, is proposed in order to evaluate the ventilation rate through an open vertical window.

Measurement were operated in Ottawa’s Laurier House (an historical house built in 1878 now being a museum) to determine the temperature and humidity conditions under which condensation occurs on ‘historic’ windows. Results lead to recommendations for oper

In this paper, the objective of the authors is to investigate the use of artificial neural networks for the prediction of air pressure coefficients across the openings in a light weight single-sided naturally ventilated test room.

Air networks are very important in indoor air quality of the patient environment. Qualitative and quantitative criteria for the design, installation and maintenance of the air network must be defined in the project.

In hospitals, legionella, humidification and indoor air quality can be mastered with simple technical equipment.

This article analyses and comments 5 papers presented at Indoor Air 2002 Conference (see Airbase records 14454, 14455, 14539, 14695 and 14697) about indoor air quality and filters, from the point of view of filter changing frequency.
