Group 5: Bioclimatic House
1. Imagine the design of the green house2. Think about the orientation of your
house3. Choose a good dimension of the
windows4. Choose „green“ materials and specific
insulation5. Use an ecologic system to produce or
save energy6. Make a big party in your biocliamtic
house all saturday
