Most Americans use air-con day-after-day, whether or not it’s in their office buildings or living areas; 90% of the country has a unit at home, and AC accounts for about 10% of worldwide electricity consumption.
However, do we even need it?
A New York Times story put that query into perspective this week. Folks in some of the hottest climates all over the world tolerate high temperatures significantly better than Americans. Citizens of nations like Mexico, Brazil, and India, use air conditioning an entire lot less than we do. The piece led to a viral debate on Twitter about whether or not AC is essential or even healthy for us.
In brief: AC won’t do a lot hurt to your health ― however, provided that the system is monitored closely and wisely. Based on a study within the International Journal of Epidemiology, occupants of air-conditioned office buildings reported symptoms of ill health than those who labored in buildings with natural ventilation.
“A big body of research has discovered that occupants of offices with air conditioning are inclined to report extra sick constructing syndrome (SBS) symptoms than occupants of naturally ventilated offices,” mentioned William Fisk, chief of Lawrence Berkeley National Laboratory’s Indoor Surroundings Group. “SBS symptoms are self-reported signs largely of eye, nose or throat irritation and respiratory symptoms similar to cough.”
“Some concern is that buildings usually are not designed for opening windows, or with cool walls, cool roofs, awnings or drapes,” he added.
While designers can change the orientation of a constructing, you possibly can’t. You may, nevertheless, move to different sides of the building without direct daylight or with extra shade. Give inventive conservation a try before you flip that AC on you could be generally better off.
