- Abstract
The article reports on the benefits of natural ventilation in buildings. Natural ventilation uses a building's form and organization, in conjunction with wind and air currents, to supply air and remove heat. Natural ventilation reduces capital and operating costs via elimination of mechanical equipment. If mechanical equipment is used, natural ventilation can reduce the size of the load, and thus, the size of the equipment and the number of operating hours. A critical factor in designing natural ventilation is minimizing internal heat gain by using strategies such as daylighting, occupancy controls, shading, and efficient equipment. Other design considerations include concentrated or distributed openings, strategies for creating openings between rooms to allow airflow, and control methods. Meteorological data is useful for determining the design elements of a naturally ventilated building. Graphical temperature data in the form of hottest days and variation during the day, as well as number of hours relative to a predetermined maximum outside temperature are useful in determining the maximum cooling loads that can be met with night ventilation.
