Lobby Windows: 1.5mtr square free vent area at 90 degrees from the opening vent. Windows should be bottom hinged open out or side hinged open out and ideally above the head of the door to clear the smoke above head height. Find Out How We Will Work With You On Your Smoke Vent Project >>
Contact UsIn the case of side hung windows, the aerodynamic free area can be calculated using the following equations: Where A = Height of Window, B = Width of Window, C = Actuator Stroke Length and D = Free Area for Inclusion in Calculation as shown in Figure 1. Figure 1.
Contact UsAwnings are primarily &39;air scoops&39;. As wind encounters a structure it has to flow up or around the object. Awnings, and awning type windows, serve to &39;catch&39; this upward flowing air and direct it into the open window. A simple double hung window captures only the air flow which directly enters it.

Let assume each window has an insect screen as well which only allows for 60% free area. The net free area of each window is now 1m2 x 60% = 0.6m2
Contact UsThe order of ventilation effectiveness is described as follows: awning window > blinds > horizontal push window (data not shown). The awning window has the following advantages: sufficient ventilation area and an adjustable opening angle to control the ventilation area and deflect rain (which is particularly suitable for the typhoon and rainy season in Taiwan).
