AC will cool you during heat waves with climatic crises. But at what price? "The Queen must feel the heat … I guess there's no airbell in # BuckinghamPalace," wrote a Twitter user, noting that the silver fan sits at the foot of the queen's gilded armchair. And while there was some speculation that the role of a fan cammer can be putting products for the famous Brexiteer James Dyson, the predominant reaction was: The Queen, she is just like us – trying to stay cool. For many people in Europe, it was not an easy task, as the heat wave has made record high temperatures in Belgium, Germany and the Netherlands in recent days. The reason? Many European cities, including London, are not meant to handle this type of heat. Air conditioning (AC) is unusual in homes in Europe, which in the past had a temperate climate, nor is it widespread in public transport systems. These infrastructure flaws were too obvious in London on Thursday when the railway authorities warned that rail rails could turn into heat while passengers hated suffocating underground wagons. Photos of a traveler without a shirt and another person who has brought a plug-in fan along their way, made tours in social media, highlighting the desperate state of affairs. Less than 5% of all European households are air conditioned, compared with more than 90% in the United States, according to the International Energy Agency (IEA). But the analysis of the same agency suggests that it will change rapidly over the next three decades, with air conditioning becoming one of the leading factors for global electricity demand. While this change will bring benefits to the welfare and productivity of many people around the world, it will lead to its own problems: AC units heat electricity and emit hot air, making the outside temperature even higher, and even more – worse, the refrigerants used in the blocks contribute to global warming.

A bioclimatic architecture that uses these energy-saving techniques and can produce AC superfluous is nothing new. Prior to the 20th century, the technique was a norm and is still visible today in local buildings ranging from Spanish farms to traditional Chinese country houses.
But with the invention of the US by the American engineer Willis HaVilland Carrie in 1902, bioclimatic decisions have fallen from fashion. Today, cooling systems account for 37% of the world's energy consumption of buildings, according to the IEA, which predicts that the use of AC will be the most powerful engine for power consumption in buildings by the middle of the century.
