Thermal behavior of window plume generated by fully developed compartment fires in single-skin and double-skin façade scenarios

Abstract The spread of fire through the façades is one of the quickest routes of spreading flames in buildings. There are three situations that can lead to the spread of fire though the façades: a) Fire from outside through hot coals, initialized/set either by a fire in a nearby building or a wooden area in flames, b) Fire started/set by an element that burns in the front of the façade (garbage container, furniture, etc.), c) Fire originated in a compartment of the building, which spreads outwards through the windows. In this paper, I focus only at the last case, which is considered to be the most dangerous and statistically the most frequently occurring. Fire spread of some type of façades were discussed: • Glazed façade, • Double-skin façade, • Façade with structural barriers, • Façade with side walls at the opening, • Façades covered by ETICS (External Thermal Insulation Composite System). Also information of influence of radiation from compartment fires to adjacent buildings was added.

The study aims to understand the thermal performance behavior of a double skin envelope system in a test cell. A rooftop observation deck and experimentation laboratory is installed at the “J” Building of the Postgraduate Unit, National Autonomous University of Mexico campus (19°18’33.59”N, 99°11’5.73”O). This platform consists of two full-scale testing modules. Each cubic module measures 3m x 3m x 3m. All of its facades have several layers of insulation. This platform was designed to test materials and construction systems under the Mexico City microclimate. It is possible to measure thermal, lighting, acoustic and indoor air quality variables. Mexico City building codes indicate that the minimum span to be used in a room must be at least 17.5% of the area of the room. Using the Experimentation Façade, which allows us to observe all available orientations; we place a window with these characteristics and measure its thermal behavior in each of the orientations. The results obtained allowed us to identify that the window when observing the North or South orientations does not greatly increase the internal temperature of the Module. On the other hand, when the window observes the orientations East and West, the internal temperature increase, establishes conditions of inhabitability inside the Module, recording temperatures of above 50°C.
