Abstract
Underground construction is a viable alternative to conventional design, especially in climates with harsh ambient conditions. In this research we analyze the natural ventilation in underground constructions, focusing on the entrance tunnel and ventilation chimney. We analyze how the differences between indoor and outdoor temperature influence the natural ventilation during periods of high outside temperature. The effect of natural ventilation in the cave ambience is also studied. For that purpose, a monitoring plan that consists of 57 sensors placed strategically according to the constructive design of the building was designed. Results show the influence of outside temperature, ventilation chimney and access tunnel on the conditions inside the underground construction. When the outside temperature is high, the design of these buildings reduces external fluctuations and the effect on the inside ambience is negligible. Due to the scarce natural ventilation (even during the night), forced ventilation is necessary when a high air exchange ratio is needed during hot period.
