Construction Of The "chimney Effect"

The development of healthy building is coinciding with saving energy, reducing pollution and sustainable development. Based on literature research, the pressure distribution and air leakage through building enclosure is discussed as a result of chimney effect. Also, the influence of the courtyard to the thermal comfort of its affiliate building is analyzed.Chimney effect refers to the pressure difference and the pattern of air flow occursacross an enclosure because of difference in the weight of the inside and outside air resulting from temperature difference, which is very important to the proper operating of building services, the improving of the thermal comfort of building, the reducing of the heating and cooling energy consumption.The Chinese tradltional courtyard dwelling building has natural heating andnatural air-conditioning effect which partly because of the effect of chimney action.The result of temperature measurement proves that the traditional courtyard has arather stable thermal quality that is valuable to improving thermal comfort of itsaffiliate building.
