Few areas can be as tough to condition as pools and ice rinks. Indoor pools, or natatoriums, need to be able to maintain a space temperature warmer than the water temperature and space humidity between 50% to 60%.
Critical facility HVAC and indoor air management is not all alike! In doing my homework for writing this column on critical facilities, I have been struck by the precision of IAQ monitoring in data centers.
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.
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.
