From Frank Liefooghe:
For centuries three concepts were upheld, when building:
This ecological dwelling goes against the mainstream:
1. The home has been built according cheap, fast and earthquake-proof principle and can be realised anywhere in the world. The building materials are natural and are not harmful to our health.
2. The building has been fashioned with a thermal isolation that leads to a constant temperature in-house. In warmer areas the inside temperature gets cooler and in cooler areas the heat is more easily retained.
3. On the roof one can install a vegetable or esthetic garden. With a vegetable garden of 5 by 10 meters one family can be provided with veggies and herbs for an entire year(plus/minus 6 people). The vegetation on the roof can cool the inside up to 9 degrees.
