This paper analyses the possibility of using air curtains to prevent smoke flow from fire compartments. Full size experiments have been carried out and several relevant conditions to assess smoke-tightness have been tested. ...

The study of the evacuation of buildings in emergency fire situations has deserved the attention of researchers for decades, particularly regarding the real-time guiding of occupants in their way to exit the building. ...

Most office buildings are designed to be ventilated and cooled using mechanical systems. However, in a temperate climate, passive ventilation and cooling techniques can reduce energy consumption when the outdoor temperatures ...

Controlling the air quality is of the utmost importance in today’s buildings. Vertical air curtains are often used to separate two different climatic zones with a view to reduce heat transfer. In fact, this research work ...

Abstract: Vertical air curtains are often used to separate two different zones to reduce contaminant transfer or even to provide aerodynamic sealing from one zone to the other. In this isothermal full-size experimental ...

Abstract: Fires in large buildings can have tragic consequences, including the loss of human lives. Despite the advancements in building construction and fire safety technologies, the unpredictable nature of fires, ...

Os túneis rodoviários longos dotados de duas galerias unidirecionais independentes são normalmente dotados de ventilação longitudinal. Este esquema de ventilação, quando aplicado ao controlo do fumo, pode gerar diferenças ...

The Indoor Environment Quality study takes on a very significant challenge when analyzed, mainly, in buildings that encompass a more sensitive and susceptible type of population, as is the case of children. To comply with ...
