Sustainable Building

Passive solar design is a method to collect solar energy using windows, walls, floors etc and distribute it to the room during winters to maintain considerably high temperature than outside or reject it to maintain inside temperature considerably cool during summer. The system does not require any mechanical or electrical devices which make it best suited for building design. Passive design takes advantage of climate in best possible way to maintain the comfortable temperature range in a room. Passive solar design eliminates the use of any auxiliary items for heating or cooling systems, which account for 35% or more reduction of energy use, saving substantial electricity bill. Buildings are properly oriented and windows are designed in such a way that they carefully balance energy requirements without adding any mechanical or electrical devices and with minimal maintenance cost. Passive Heating and Cooling Masonry walls properly oriented towards south with allowance of 30 deg
