The World Health Organization estimates that 30 percent of buildings exhibit sick-building syndrome. How can you tell if your hospital suffers from SBS? Your staff may complain of headaches; eye, nose, or throat irritation; itchy skin; dizziness and nausea; difficulty concentrating; fatigue; or sensitivity to odors--symptoms that disappear once a person leaves the hospital. Although such symptoms may indicate another illness, studies show that indoor air pollution can exacerbate health problems.
Q. How does one calculate how much air movement is appropriate in a kennel? I'm concerned that several air exchanges per hour would pump large amounts of heat and air conditioning through the wall we so carefully sealed and insulated. A large window unit cools our kennel; should I allow it to vent at all times? Is an interior circulating fan required to move out stale air?
