INVESTIGATION ON PARAMETER INFLUENCING THE EFFICIENCY OF PASSIVE COOLING OF A TWIN BUILDING

Passive cooling techniques are the approaches with can replace the conventional cooling method to provide space cooling for a building with low or no energy consumption. Conventional cooling method requires high energy consumption and at the same time releases tremendous amount of greenhouse ga...
