Passive design is a system or structure that directly uses natural energy such as sunlight, wind, temperature differences or gravity to achieve a result without electricity or fuel. Active design is a system or structure that uses or produces electricity.The term passive design is most often used with respect to architecture and infrastructure. For example, a building may have wide windows that automatically let in more light when the building needs heat and automatically shade when the building is too hot. Another common area of passive design is wet infrastructure such as drainage systems that generally often don't consume power but use gravity to move water.Most devices and infrastructure have an active design as they use electricity. The term is typically only used in comparison to passive designs. For example, solar panels that produce electricity are often referred to as active solar as a comparison to using solar passively for heat or to grow plants.
Passive BenefitsPassive designs are often valued for their simplicity and aesthetic appeal. They also tend to have zero operational costs. As they often contain no moving parts, passive designs potentially last for centuries.Electrical components are valued for their accuracy and functionality but may need to be regularly maintained and replaced. They may also have a higher operational cost and environmental impact.
