Vì Sao Châu Âu Ít Lắp Điều Hòa? Bí Mật Khiến Nhà Vẫn Mát Dù Nắng 40°C

When summer temperatures in Europe sometimes exceed 40°C, many people are surprised to find that many homes still don't have air conditioning. This leads many to wonder: How can they live in such heat? In reality, the reason isn't that Europeans can't afford air conditioning, but rather a combination of climate, architecture, history, culture, and urban planning that has created homes capable of naturally staying cool for hundreds of years. In this video, we'll explore: Why Europe's climate once didn't require air conditioning. The secret of thick stone walls and ancient shutters. Why nights in Europe help cool entire houses. Why electricity prices and energy-saving culture influence the decision to install air conditioning. Why many ancient cities don't allow the installation of outdoor units. What's changing as climate change causes Europe to heat up year after year. And lessons that cities around the world can learn to save energy in the future.
