Indoor Ventilation Simulation in Green Building Based on Airpak

With the rapid development of science and technology, energy shortage cannot be ignored and energy conservation and emission reduction has been paid worldwide attention. As an important technology of building energy efficiency, natural ventilation can not only meet the room comfort index, save the equipments and running costs, but also create sustainable development of green building environment. Based on the typical residential building, corresponding model is established by the computational fluid dynamics software called Airpak. Through numerical simulation under the different conditions of ventilation environment, we discuss the important role of natural ventilation in building energy-saving field and improving indoor air quality, and give related suggestions for building energy-saving, environmental protection and safety of living environment.
