The solar chimney is a reliable passive ventilation system that can largely reduce the energy requirements with both low costs and maintenance for buildings to overcome the current energy crisis. To optimize its design, an empirical model is developed to predict the performance of typical solar chimneys considering both room and chimney cavity configurations using easily acquired inputs. Fire Dynamics Simulator (FDS) as an excellent and open-source tool to solve heating, ventilation and air conditioning problems is selected for this study. The numerical modelling of FDS was first validated by previous experimental data, and then used to develop the empirical model. In this model, a coefficient describing room and chimney configuration (e.g., room opening, inlet and outlet of cavity) is proposed.

“…High-temperature hot smoke will spread quickly from the fire floor to other floors through stairwells [1], glass curtain wall, and elevator shafts by stack effect [2][3][4][5][6]. Ayala et al [5] investigated the influence of different atrium roof geometries on large-scale atrium natural venting conditions and the influence of the atrium aspect ratio on the smoke layer growth by numerical simulations and experimental fire tests.…”

“…Other academic research regarding and investigations into fire accidents have been conducted using fullscale fire site simulation experiments 7,8 and simulation software. [9][10][11][12] Because computer simulations can generate results approximating those of full-scale experiments and investigation reports and also require less resources and work, such simulations have become preferred for research.…”

The occupants inside the fire site often only have a few minutes to evacuate, which is referred to as the golden evacuation time. In this study, total evacuation time was divided into response time, moving time, and waiting time. A regression model was adopted to incorporate three independent variables (floor area, number of exits, and per-floor occupant load) and determine their effect on a dependent variable, called as the evacuation time. Despite its widespread use in multiple domains, regression analysis has not been used to explore the evacuation time. The total evacuation time is to leave a fire site can successfully escape the fire. Here, the results indicated that the occupants left a fire site less than the total evacuation time. The total evacuation time calculation can also be applied to a fire protection system; this allows emergency personnel to update the total evacuation time in real time, while simultaneously informing occupants of the remaining available time to safely escape from a fire site. This study showed that regression analysis is a useful method for evacuation time calculation and can serve as an assessment tool in fire accident-related scientific research and accident investigation.
