24 housing, limiting the temperature rise indoors and cooling it in summer. When it comes to this principle of maintaining moderate temperatures, certain age-old architectural practices are also proving extremely pertinent, such as the construction of wind towers (natural ventilation system inspired by the Middle East), cross ventilation (creation of smart air flows), using terracotta with excellent thermal performance, etc. TOWARDMORE VIRTUOUS AIR CONDITIONING In parallel, innovation in terms of air conditioners themselves is continuing to make them greener. Many start-ups are working on more energy-efficient equipment whose temperature cannot go below 24 °C. Others are coming up with alternative cooling systems. Already tried and tested in Austria and Switzerland, the 22‑26 concept (with an indoor temperature oscillating between In New Delhi (India), air conditioners cover the façades of buildings, yet fewer than 11% of Indian households have air conditioning. x 3 The IEA predicts that the number of air conditioners worldwide will triple by 2050 with the increase in income in emerging countries.
