>...In the Swiss canton of Geneva, installing an air conditioner requires an exceptional permit demonstrating “real need” (such as a doctor’s certificate). During the recent energy crisis, Spain and Italy barred public buildings from cooling below 27°C—hot enough to dull your cognitive powers by 5 percent. In the midst of the current deadly heat wave, my own city of Ghent is officially advising people to “avoid air-conditioners”.

>The resistance is baked into European regulation. In many countries a conventional air conditioner lowers your building’s energy rating. The result is entirely predictable: owners and landlords decline to install units, or rip out the ones they have. Those left without built-in cooling fall back on drafty, inefficient portables that can scarcely make a dent in the temperature. I own one myself—a wheezing box with a fat hose shoved through a rickety fabric covering the window. It is the thermodynamic equivalent of mopping the floor with the tap running, but that’s simply the direction in which Europe’s regulations have nudged me.
