An active facade system is a building facade that uses technology to control environmental conditions, such as temperature, humidity, and air quality. This technology can include sensors, actuators, and energy-efficient materials such as photovoltaic panels or smart glass. The active facade system actively responds to changes in the environment to optimize the indoor space for occupants and minimize energy consumption.
On the other hand, a passive facade system is a building facade that relies on natural resources such as sunlight, natural ventilation, and shading to control environmental conditions. Passive facade systems use design strategies such as orientation, building shape, and material selection to create an energy-efficient building envelope. The passive facade system does not actively respond to environmental changes but instead relies on a well-designed building envelope to maintain comfort and reduce energy consumption.
In summary, the primary difference between active and passive facade systems is that active systems use technology to actively control environmental conditions, while passive systems rely on natural resources and design strategies to achieve the same goal.
