Fans blasting in various directions, air conditioning turned up to the max, portable cooling devices held up on public transport and bottles of water everywhere you look: the ways Brits are coping with the ongoing heatwave are numerous.But in some parts of Europe, residents have an easier time when the temperatures reach astronomical heights.Unlike man-made air conditioning and battery-powered fans, some cooling systems across the continent occur completely naturally.From cave villages in France to ancient aqueducts keeping towns and cities cool, there are a range of weird and wonderful processes that do the work of technology.And if you’re feeling really hot, perhaps it’s time to book a trip to one of these destinations – weekend in Italy, anyone?Here’s a rundown of some of the best natural phenomena across Europe keeping destinations well below scorching temperatures… The cave village of Trôo, France In a troglodyte village in the Loire Valley, homes stay naturally cool amid heatwavesIn Trôo, France, residents have reported that their homes stay naturally cool even when it’s hot outside – and that’s down to their dwellings being housed in caves.Trôo is located near Tours, in the Loire Valley. The troglodyte village, literally meaning ‘cave dweller’, has homes carved into rock that remain cool as a result of the thick layer of surrounding rock.Resident Dominique Opéron told Euronews that temperatures inside are around 20C – even if the outside temperature exceeds 35C. Local tourism association chairman, Jean-Luc Eclercy-Deterpigny, said that cave living is ‘an incredible stroke of luck’ amid climate change.He noted residents rely on the natural cooling effect of the rock as heatwaves hit the region.Ancient aqueducts in Naples Naples is in the process of using ancient aqueducts and natural resources to keep coolA blend of natural resources – water and minerals – and ancient aqueducts form Naples’ underground resources, and could even be used to combat heatwaves spreading across Italy.’Naples is historically a relatively poor city with high levels of unemployment, and it’s also a place that is expected to experience two to three months of extreme heat by the middle of this century,’ architect Nick De Pace told NBC News. That’s where Cool City comes in – an initiative to use the city’s natural and historic resources to reinvent the way the city stays cool. The official website says: ‘Since 2019, Project Cool City has been exploring ways to reactivate the ancient aqueducts, cisterns, and fountains in Naples, in order to counteract heat islands in the city from global warming and urban developments. ‘By bringing up cool water and air from its forgotten underground infrastructure from [the] Ancient Greek and Roman period, we want to create new community spaces and public life that promotes ecological future. ‘Project Cool City will investigate and learn from the hydrology of Naples, and its vast varieties of water and minerals gifted from the special biodiversity of its volcanic history.’Cooling caves of Switzerland Switzerland’s cooling caves also provide natural ways of avoiding heatIn Switzerland’s Ticino region, grotti were originally storehouses made from the natural landscape in order to keep wine, cheese, fruit and vegetables cool.Nowadays, while many retain their initial purpose, some have been converted into eating and drinking establishments – that remain naturally cool.They were formed following landslides in the region; these natural occurrences created caverns in the rock.Reportedly initially discovered by goats, farmers then found the caves, the BBC said.They were then expanded by locals, who added doors or built homes on top in order to enjoy airflow from below and keep the house temperature cool. Alpine Thermal Siphons, Slovenia and Austria Destinations such as Lake Bled stay cooler as a result of mountain windsTowns such as Lake Bled in Slovenia, in the Julian Alps, stay cool due to their natural geography.When temperatures rise during the day, the nearby mountains heat up more slowly than the valley. As a result, cool mountain breezes known as katabatic winds push fresh air into the towns. This means areas in this part of the world stay cooler as a consequence. Italy’s 16th-century geothermal cooling system A study has revealed how historic Italian villas have systems that keep them coolThe geothermal cooling system of six 16th-century villas in Costozza (Vicenza, Italy) has been analysed in a study.While it might not be a natural phenomenon, it’s one that has stood for centuries – and uses naturally occurring caves. The study reveals: ‘The system passively cools the villas in summertime by means of underground ducts connected to the caves present in the nearby hills. ‘Furthermore, the ancient cooling system can be used as a reference for how geothermal renewable resources can be used to improve indoor comfort and limit energy consumption in modern buildings in a temperate climate. ‘The system can provide fresh airflow rates that cool the walls of the room and maintain the temperature below 20C, even on hot summer days. ‘An advantage is that the system works in a self-adaptive way; the airflow increases when the outdoor temperature increases. This self-adjustment allows us to compare the cooling system to a modern environmental control system.’
