Indoor Environment and Natural Ventilation

The aim of ventilation is to ensure the good characters of the indoor air condition.One of the key issues in the ecological design process of the buildings is the application of natural ventilation.A good natural ventilation system is an effective approach to reduce the dependence of the indoor air condition on the mechanical air conditioning system,drain away the indoor air pollutants efficiently and improve the indoor air quality.The indoor thermal environment operated by the natural ventilation has beneficial effect on the thermal comfort of human beings.Authors presented the study on the influences of natural ventilation in the ecological buildings on the indoor air quality and the indoor thermal environment by investigating a big set of data.The approach to improve the indoor environment in the buildings by the application of natural ventilation was discussed.The appropriate design method was concluded and highlighted.The results show that designing reasonable natural ventilation,the indoor air quality and the indoor thermal environment will be improved effectively.
