We will conduct a natural ventilation analysis of buildings with high ceilings during the summer and in calm conditions.
The natural ventilation analysis of high-ceiling spaces conducts an examination of natural ventilation in buildings with high ceilings during the summer and in calm conditions. In large spaces, there is often a trial-and-error approach to maintaining a comfortable temperature distribution by not solely relying on air conditioning but also expecting natural ventilation. During the summer and transitional periods, the temperature distribution within the space often stratifies, with higher temperatures at the top due to solar radiation and wall convection. Therefore, if there are openings at the upper part, density-driven convection can occur, allowing hot air to be expelled outside the building. In recent thermal environment analyses, if the size, position, and opening ratio of the openings are known, it is also possible to directly calculate the ventilation airflow rate.

basic information
【Analysis Model】 - Accurately reproduces the size of the space, the shape of the building's roof, and the position and size of the grilles in accordance with the actual structure. - The number of grids is 152×85×54 = 697,680. - The internal structure of the building is also detailed as it greatly influences the characteristics of airflow. - By including the external space in the analysis, it is possible to evaluate the ventilation airflow quite accurately. 【Analysis Results】 - Thermal conditions consider heat intrusion into the space from solar radiation on the roof, as well as human and lighting loads within the building. - Openings are located at the top of the grilles, and the intrusion of outside air from the airlock is also taken into account. - Exhaust conditions with a pressurized fan are set at the ends of the building. - In the space near the airlock, the temperature rises by 1-2°C compared to the outside air temperature (33°C), and in the waiting area at the ends where many people gather, the rise is about 5°C. - Natural ventilation analysis under the influence of external wind, defined by external airflow, is also possible. ● For more details, please contact us or download the catalog.
