A wide range of pollutants has been found indoors and their adverse effect on occupants’ health has been recognized. Gaseous and particulate pollutants may spread indoors from one zone to another though improperly designed airflow distribution system. Airborne transmission of respiratory infectious diseases indoors has been recongnised as well. Air distribution in spaces is important for transport of pollution and viruses and the exposure of occupants. At present increase of ventilation rate is recommended for reduction of exposure, mainly due to dilution. However, the increase of the ventilation rate leads to increase of energy consumption and need of large and costly ventilation systems. Instead, proper design and control of air distribution in spaces can be considered. This is in the focus of a new REHVA Guidebook on Target Ventilation. The guidebook and the present and future activities in its preparation will be presented and discussed. The details of the work will be reported in several resentation the the members of the group working on the guidebook. The goal is to inform the community and discuss the work performed so far on the guidebook and to collect rational suggestions for the improvement of the work on the guidebook.
The objective of this workshop is to present the new REHVA Guidebook on Target Vnetilation, to discuss the ongoing work and to collect suggestions for its improvement.
