INSULATION RENOVATION EXPERIENCES
— We Expect The World To Follow
With over 20 years' of central air conditioning serving experiences in 70+countries, we realized that uninsulated buildings have caused the biggest energy waste in the world, which is far beyond anybody's imagination. Started from 2008,we decided to renovate the buildings in BROAD Town, to explore for the humankind a full set of e xperiences of using less air conditioning. Now by sharing what we've discovered, we hope you can follow and do ther mal renovation by yourselves
BROAD Town is located on the outskirts of Changsha, South China. Changsha (N 28°, E113°), has 4-5 cold months and 5-6 hot months, lowest temperature is -10 °C and highest 43°C. Only 1-3 months can be free from air conitioning in a year. This kind of climate is very typical globally, as in Shanghai, Osaka, Washington, D.C., Roma, etc.
