| Outline of Final Research Achievements |
Various measurement and estimation methods of natural ventilation rate were investigated in the real buildings. The method should be conducted for long period and is possible to validate the quantitative effect of the natural ventilation. The final goal of this study is to propose the simplified commissioning method of natural ventilation as the standard method. Measurement of the pressure differences at the wall was found to have enough accuracy for practical use. Compensation was possible of the measured pressure difference that is not go trough the outer wall. The estimation of the ventilation rate by the outer surface pressure and by the network calculation using the fixed indoor temperature obtained from BEMS were possible as well. Indoor air quality was verified to be increase during the natural ventilation usage from the long-term measurement of the indoor environment. Also a kind of the design charts of natural ventiation were proposed by network calculation.
