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.

We continue our multifaceted look at the critical issue of hospital-acquired infections (HAI), this time through the prism of an industry veteran discussing ultraviolet germi-cidal irradiation and the role it can play in preserving patient health.

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.

Treasure Coast Hospice has successfully reduced its HVAC maintenance costs, increased unit efficiencies, and extended equipment lifecycles while simultaneously increasing patient IAQ.

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.

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.

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.

Happy new year, readers! And a sincere thanks for making time to include ES in your professional life.
