Green buildings are a promising solution to urban air pollution as they focus on improving indoor air quality through innovative technologies and practices. Green roofs and walls act as natural filters, absorbing pollutants and dust particles while releasing oxygen and regulating building temperatures. They can remove up to 80% of airborne particulate matter from urban environments. Green buildings also use enhanced ventilation systems incorporating advanced air filtration technologies to remove contaminants and allergens before they can affect occupants.Additionally, strategically placed fire-rated access doors, like Fire-Rated Insulated Access Doors, improve air quality by providing a barrier against smoke and fire infiltration. These doors maintain integrity during a fire, helping slow down the spread of fire for a limited period.
