A green building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building. The idea of green buildings is to embrace an Eco-friendly style of living. Designed for natural light, the green building promise to save up to 35% of energy consumption and 30% on water consumption. The entire raw material used to make a green building comes from recycling matter. The walls are insulated to reduce the flow of heat from outside. At GPS, ACC blocks have been used in the construction of the building. This would render the temperature of the building 3-50C lower then natural outside temperature during the scorching summer heat but would not at all affect or lower the warmth and coziness produced inside the classrooms during the winter season.
