Can’t Stand the Heat?

Early last week the Energy Star program people released recommendations on home heating and cooling. The reaction was swift and negative.

I could not find a date on this posting, but I know that for many years the recommended residential temperature setting has been the same as presented there. “The U.S. Department of Energy recommends that home temperature be set to 68 degrees Fahrenheit in the winter and 78 degrees Fahrenheit in the summer. When no one is home, adjust temperatures to cooler settings in the winter and warmer settings in the summer.” For a long time it was no big deal. Many utilities have been subsidizing the cost of a programmable thermostat to facilitate meeting this pattern of adjustment.

But for some reason when Energy Star, a program of the U.S. Environmental Protection Agency and the U.S. Department of Energy, last week came out with the idea of setting the summer temperature at 78 degrees to save energy during the spring and summer, ABC news said it “surprised” the Internet. They went on to post numerous tweets protesting 78 degrees as too hot.

MSN expanded on the story. “The Energy Star program recommends that people increase their air conditioning by seven degrees when they are not at home and by four degrees when they are sleeping, depending on what temperature makes them comfortable.” That translates to 85 degrees when you are out and 82 degrees when you are sleeping, or trying to sleep. The story explains how it went “viral,” in a negative way, and included another set of Twitter examples.

One says: “WHO CAN STAND 80+ DEGREES WHEN THEY'RE SLEEPING I WOULD MELT TO DEATH.” Another is concerned about the dog’s comfort if the temperature is set up during the day. One example on both sites asks, “You know how hot 78 degrees is?” 

Well, the answer is yes, I do know how hot 78 is – and so do many other people. It was not that long ago that home air conditioning was not all that common. The number of houses with central air conditioning rose from 19% in 1973 to 72% in 2009. I could not find numbers for the 1960s, but a reasonable guess would be about 10% or less. According to Consumer Reports, today “more than 75 percent of U.S. homes use air conditioning, and 90 percent of new homes are equipped with central air.” 

Most of the complainers are not old enough to remember the days of no air conditioning when city folks sat out on the fire escapes at night, and others set up mattresses in the cooler basements, when breaks from the summer heat consisted of opening a fire hydrant or going to the pool or to one of the few air conditioned buildings in town, the movie theater. 

That was reality only a couple of generations ago! Somehow the majority of people struggled through. No one melted to death. Dogs weren’t dying at home while everyone was at school or work. If it was hot at night, too bad. It’s true that 82 degrees is not nearly the ideal temperature for sleeping, but having to sleep at that temperature or higher in the past, because there was no other choice, did not result in mass extinction!

Several news outlets that released the Energy Star guidelines mentioned also that July was the hottest month ever recorded on Earth. This links the renewed recommendation with climate change efforts, where everyone is expected to do their share – except they don’t want to. It’s the Al Gore philosophy – express a ton of concern about the planet, then go about business as usual.

This entire episode shows why perspective is so important. Without it, gratitude is lost. Technology is moving ahead so fast that everyday life of a few generations ago seems like ancient history. Minor inconveniences become major hardships. People don’t stop to think how lucky we are to have air conditioning almost everywhere. Instead they fly to Twitter to rail on about the injustice of it all.
