\.ASHRAE (American Society of Heating, Refrigerating, and Air-conditioning
Engineers, Inc.) - ANSWERS✔-· Recommends that ventilation be increased in all
residential, commercial, and industrial buildings

\.Relative Humidity - ANSWERS✔-is the amount of moisture in the air compared
to the amount it would hold if the air were saturated
\.Dew point - ANSWERS✔-The temperature below which moisture in the air
begins to condense.
