How the houses were ventilated in past!

Archeological records provide several examples of how houses were built to accommodate ventilation and improve indoor air quality. Various approaches were developed to deal with the use of fires inside dwellings.

  • In 4,000 – 5,000 B.C., the Banpo villagers in China incorporated chimneys into their homes.
  • The Romans put a vent hole in the middle of their houses’ flat roofs to vent smoke out of the living quarters.
  • The basket weaver’s pit houses found in Mesa Verde National Park, circa 750 A.D., use this same approach.
  • Teepees, with their vent holes at the top and openings around the bottom were designed to accommodate fires and ventilation. The teepee doors could be positioned to control airflow.
