Finishing the discussion started in our September issue, the author turns his focus to the requirements and tips behind good life safety design for some special locations in health care facilities. From the narrow confines of a stairwell to the wide open spaces created by an atrium, there's always room for error if you're not paying attention.
Part one of two, this feature examines the special concerns that hospitals (and their associated standards) create for air handling and smoke control design. The article starts with basics and moves on to more involved scenarios and sequences, while the sequel will go on to explore the relationship between life safety systems and controls.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
