1.1.4 Manage properly the opening of windows and doors for natural ventilation

1.1.4 Manage properly the opening of windows and doors for natural ventilation

Description

To improve air comfort and reduce the need of HVAC systems use natural ventilation. Open windows of opposite façades to produce cross-ventilation or if the building has a space for vertical circulation or a central courtyard, open windows and/or doors at different heights to generate a vertical ventilation and expulse warm air.

Benefits

  • Natural and healthy
  • It improves the quality of air
  • Reduce the use of cooling systems

Limitations

  • Occupant acceptance

  • The quality of ventilation achieved by opening the windows will depend on the outdoor wind regime
  • It should be done in a controlled way so that air speed is compatible with the improvement of the comfort feeling
  • Outdoor air currents to properly ventilate the building are difficult to find in cities

Economic assessment

The initial investment is zero, although it is convenient to train and inform properly users on these issues. It reduces the costs associated to the HVAC system.
