In times of heated discussions about sustainability and energy efficiency, the past offers a valuable lesson. At China, an ancient nation, there are countless examples of ancestral techniques and practices that go beyond time in terms of efficiency.
One of them, particularly intriguing, is an ingenious form of air conditioning that replaces the use of modern air conditioning: Casas de Terra Fresca.

These houses, also known as “Yao Houses”, are traditionally built in regions with warmer climates in China.
Instead of relying on the electrical technology we know today, these homes use a combination of specific positioning, design and materials to keep environments cool in summer and warm in winter.
Yao Houses are often semi-buried, taking advantage of the earth's natural ability to regulate temperature. During the warmer months, the soil acts as a natural insulator, while in winter it acts as a blanket, storing heat.
The orientation of the house in relation to the sun is essential. Openings, such as windows and doors, are strategically positioned to allow light to enter and air to circulate optimally. Internal courtyards and ventilated corridors promote the circulation of fresh air.
Clay bricks, local wood and lime-based mortars are the protagonists. These materials, all readily available and biodegradable, not only have excellent thermal insulation properties, but are also sustainable and environmentally responsible.
In an era where we are constantly seeking technological innovations, it is almost poetic that a solution to thermal comfort can be found in centuries-old practices.
Yao Houses remind us of the importance of living in harmony with nature and valuing the knowledge of our ancestors.
Today, while some choose to modernize and adapt these ancient techniques, in China, many still prefer Yao Houses in their traditional form.
And for those who care about the environment, these homes serve as an inspiring reminder that sometimes the best technology is the one that's been around for a long time.
