After more than 20 years of coaching, Queens University (QU) head swim coach Jeff Dugdale has seen his share of coughing, wheezing, and breathalyzers from poor IAQ at indoor swim meets.
Environmental factors, IAQ-related codes and standards, even architectural building materials … a lot of factors combine to create a moving target for designers of good humidification systems. That’s not even considering the potential hiccups lurking in the construction process or resulting from an inattentive project team member. From the humidity basics to equipment placement to post-occupancy maintenance that can thwart lawsuits, pursue the path to appropriate humidity and minimal risk.
One of the challenges we have with commercial buildings is the fine line between providing a safe and healthy indoor environment and maximizing energy efficiency.
One of the primary objectives of the model building codes is to minimize the impact of fire, including reducing to the greatest extent possible the spread of fire and smoke floor-to-floor.
Thanks to foodservice air curtains as part of a $10 million renovation at McKechnie Field, the only flies near concessions are those of the foul ball nature.
Treasure Coast Hospice has successfully reduced its HVAC maintenance costs, increased unit efficiencies, and extended equipment lifecycles while simultaneously increasing patient IAQ.
Most people are well aware that outdoor air pollution can damage their health, but many are not aware of the serious harm that indoor air pollution, or contamination, can also cause.
For many years, duct products have often involved significant on-site measurement and construction, bringing certain advantages and risks. Here, that practice is com-pared to the use of listed ductwork, with an eye on duct integrity, hood connections, clearance to combustibles,
fire ratings, and more.
At Walter Reed National Military Medical Center, the mission was an air handling overhaul without interrupting the usual delivery of care. The project team delivered a safer, upgraded environment via a new desiccant system, air handlers, increased flexibility in the surgical suites, and more.
Air changes in some but not all spaces, duct liner here but not necessarily there, rooftop unit requirements … do the rounds and get a feel for the current condition of ASHRAE Standard 170, Ventilation of Health Care Facilities.
