During the ASHRAE 2015 Winter Meeting in Chicago, REHVA and ASHRAE presented together the result of important collaboration work between volunteers / engineers of both societies: The publish of the ‘Active and Passive Beam Application Design Guide’.

It gives system designers a current, authoritative guide on successfully applying active and passive beam technology. This new guide is based on the REHVA Guidebook nr.5, previously published, the ‘Chilled beam application guidebook’.

This new guide provides up to date tools and advice for designing, commissioning and operating chilled-beam systems to achieve a determined indoor climate and includes examples of active and passive beam calculations and selections.

REHVA’s co-editor John Woollett (Swegon), said that ‘Active and passive beam systems provide good thermal comfort and energy and space saving advantages, and the operation of such systems is simple, with low maintenance requirements. In a building where the goal is a low energy usage index, beams can be an excellent choice of indoor climate product’. The book provides information on the basics of operation but also background from engineers developing the beam technology with manufacturers. The main focus is comfort beam application in their passive and active variants. They have specific applications and work well in commercial office building, schools, hospital patient rooms, laboratories and hotels, John Woollett says.

This Guide is available throughwww.rehva.eu.
