A healthcare facility engineer must be able to explain how their building was designed and performs in areas of air pressure, temperature and humidity, according to an article on the Health Facilities Management website.
Air quality's role in infection prevention can be overlooked, so having the right tools to communicate the importance of temperature and humidity is important.
Engineers have been using the same psychrometric chart since 1904, and have struggled to convey the fundamentals to building occupants for more than 100 years.
Eventually they realized that the relationship between temperature and humidity can be demonstrated by using 500 milliliter beakers.
