Passive Design for Smart Building

Throughout the life cycle of a building, from construction, operation, and demolition, consumes a lot of energy. Accordingly, improving the efficiency of one step of the life cycle can significantly reduce the carbon footprint of the building. One notable way to do this is to practice better passive design that will eventually reduce the energy demand. 

• 22% energy can be saved with well-insulated building envelop.
• Heat gain/loss from windows can be minimised with a proper window-to-wall rasio.
• Passive heating can be achieved by utilising solar heat such as Trombe wall technology.
• Proper ventilation can help to reduce energy for cooling for up to 38%, while green roof for up to 19%.

In addition, passive design for cooling and heating could be complemented by other Heating, Ventilation and Air Conditioning (HVAC) to further reduce the energy used for a building while ensuring better comfort for the occupants.
