Chapter 7 of the International Building Code (IBC)1 requires life safety dampers to protect duct and air transfer openings within building separations — fire walls, fire barriers, fire partitions, horizontal assemblies, smoke barriers, and smoke partitions.
Picking up from my last article in the June 2019 issue, I will explore some context for real-world life safety applications. In this article, I’ll focus on complying with NFPA 99 (Section references to 2018 ed.) and its referenced standards as resources for your health care facilities’ HVAC designs.
Picking up from my last article, “Smoke Control Infrastructure Pitfalls” (December 2018), we will explore some context for real-world smoke control applications with a focus on using NFPA 92 as a resource for your smoke control rational analysis development in this article.
Restaurants and commercial kitchens are notoriously one of the largest consumers of energy per unit of floor area. Moreover, the kitchen ventilation system is often the largest energy-consuming component in a food service facility.
This month's Facility Files will focus on the Back2Basics test addressing the renovation of an existing Metro station with the addition of a new smoke evacuation system located within the building and within the subway’s inbound and outbound tunnels. The associated ADA-compliant elevator will have its own stand-alone, engineered, smoke control, 100 percent outside air fan to a positive-pressurized elevator shaft system.
Whether we’re talking a single building or a larger campus, proper strategy for this key HVAC component requires the right team working at the right times. Both physical and fiscal safety may depend on it.
According to Det-Tronics, its SmokeWatch™ U5015 uses advanced photoelectric smoke detection technology not generally available in an explosion-proof housing. The detector is rated for Class 1 Division 1, 2, and Zone 1 environments found in industrial applications. Used with the Q5016 Duct Mount Accessory, the detector can be installed on ductwork to meet NFPA 90A requirements for AHUs of more than 2,000 cfm.
Engineered Systems magazine’s May 2020 issue examines the revitalization of air-cooled chillers in data center facilities, the viability (or lack thereof) of duct systems, the impact the coronavirus is having on the built environment, and much more.
