This month, our life safety coverage arrives from the commissioning side. From design phase to tips on navigating a seemingly untenable number of observations, and on to post-testing tasks, here’s one consultant’s solid reference to keep you and your client from getting unnecessarily alarmed.
Incorporating a plenum can have its design advantages, but corridors serving adjoining areas of health care occupancies are prohibited from being used for a portion of an air supply, air return, or exhaust air plenum. This article and its illustrations can strengthen your grasp of the related NFPA code details and exceptions so you can design and ventilate properly for this special population.
Defending against even a simple airborne attack may require a complex

strategy. Sensor capabilities, sensor placement, response speed, and
the general ventilation system are some of the factors that play into
protecting occupants (and even property) in the case of something
worse than an accident.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
