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).
