What are passive doors and windows?
Passive doors and windows are not an energy consumption standard, but a systematic door and window solution that balances efficiency, architectural appearance, and good comfort. The "passive design" applies natural principles such as sunlight, wind, temperature, and humidity in nature. It relies as little as possible on the consumption of conventional energy, and improves and creates a living environment through architectural methods such as planning, design, and environmental configuration. Basically, no additional heating or cooling equipment is needed.
