  4. 4. TURBULANCE Roughness creates mechanical turbulence, while surface heating causes thermal turbulence in the airflow.
  5. 5. Air movement through the building is due to; • Wind Pressure • Stack effect • Combustion and Ventilation
  6. 6. Pairing a large outlet with a small inlet increases incoming wind speed.
  7. 7. Building structures can redirect prevailing winds to cross-ventilation
  8. 8. Venturi Effect
  9. 9. Stack Effect / Chimney Effect
  10. 10. Solar Chimney
