1 Principles of Sustainability in Green Homes TERI Housing, Gwal Pahari Farmhouse, Ghitorni Vertical Green city, Pollachi By: Prof. Charanjit S Shah Abuilt form should not be treated as a mass of brick and concrete, but as a living organism. The built form needs to breathe and be embodied with the environment
