Renewed concern about a building's response to a potential biological threat hasn't led to any "quick fix." ASHRAE and the industry in general continue to look for ways to identify both problems and options for owners and engineers.
A difficult project is one thing, but entering a project in medias res can prove even trickier. See how one consulting firm helped steer a major federal facility overhaul toward greater efficiency and a new degree of controls interoperability, all on a tight schedule. By Joanna Turpin
Hollywood and Highland is no longer just an intersection - it's 2 million square feet of multiuse commercial space where visitors can do everything from grab lunch to attend the Academy Awards. Designers faced the usual space challenges, but other special concerns ranged from adjusting to the facility's late classification as a high-rise building to supporting Wolfgang Puck's kitchen.

They're rarely in the spotlight, but cooling towers house multiple, often overlooked chances to reduce the bottom line. From initial design to renovation options, a little forethought can lift efficiency to new heights. By Joanna R. Turpin
Providing just enough ventilation for the amount of people using a space at a given time? The concept's logic is appealing, but when it comes to conforming to Standard 62.1, the details may prove more vexing. By Joanna Turpin
In today's energy climate, any existing strategy is worth a second look. The curious can start here by learning its strengths and weaknesses, examining possible applications, and sampling such units on today's market. By Joanna R. Turpin
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.
