HOW DO THE PASSIVE DESIGN STRATEGIES MINIMIZE THE ENERGY CONSUMPTION?

Passive Design

Passive Cooling

Natural Lighting

Reduced the need for active cooling

No need for mechanical

lighting during the day

Reduced usages of electrical appliances to achieve users

comfort

Lower energy consumption
