REHVA -- Ventilation Effectiveness PDF

Improving the ventilation effectiveness allows the indoor air quality to be significantly enhanced without the need for higher air changes in the building, thereby avoiding the higher capital costs and energy consumption associated with increasing the ventilation rates. This guidebook presents the practical research on ventilation effectiveness and also illustrates its application with case studies.

This guidebook is aimed at practicing, consulting and contracting engineers. It provides easy-to-understand descriptions of the indices used to measure the performance of a ventilation system and which indices to use in different cases.

It also demonstrates how to measure ventilation effectiveness in practice. Use of tracer gases, measurement equipment and how to perform measurement and calculations are introduced. Eight practical case studies are also presented and discussed.

Ventilation effectiveness is the common notion for the indices used to characterize the ability of a ventilation system to exchange the air in the room and the ability of a ventilation system to remove air-borne contaminants. Size: 7"X 9". Soft cover.
