□ Natural Ventilation Control Algorithm for Energy Saving in Office Buildings

 As an energy conservation measure used in building operation phase, natural ventilation has become a focus of attention. With the technological progress of building energy management system, automatically controlled natural ventilation systems have been installed in several buildings in Japan. However, several issues about control criteria are still in question. Furthermore faulty natural ventilation operation is often performed in real projects, for example ventilation windows incorrectly open or close, natural ventilation deteriorates the indoor thermal environment and sometimes even increases air conditioning load.
