Abstract :
The paper investigates a single-sided naturally ventilated buildings potential model considering number of factors in China. This
model can be used to estimate potential of natural ventilation via local climate data and building parameters. The main goal of the model
is to predict natural ventilation hours and hourly ventilation flow rate. In fluid model, formula of single-sided natural ventilation by
coupling wind pressure and temperature difference was used to calculate air flow rate. Accordingly, the paper analyzed four typical cities
in different climate region in China and calculated pressure difference Pascal hours (PDPH). The results show that single-sided ventilation
has fewer adaptive comfort hours than two-sided ventilation and much less ventilation volume. This model provided quantitative information
for early stage architectural natural ventilation design and building energy efficiency evaluation.
