What is a vertical shadow angle?

What is a vertical shadow angle?

Similarly, the vertical shadow angle (V.S.A.) is the angle, on a vertical section drawing of the wall, between a line perpendicular to the wall and the projection of the sun’s rays on the plane of the drawing.

What is vertical sun angle?

Solar altitude angle, α The solar altitude angle is the angle between the sun’s rays and a horizontal plane, as shown in Figure 2.8. It is related to the solar zenith angle, Φ, which is the angle between the sun’s rays and the vertical. Therefore, Figure 2.8.

What is HSA and VSA?

These are the horizontal shadow angle (HSA) and vertical shadow angle (VSA). These angles express the sun’s position in relation to a building façade at a given orientation and can be used to show the performance of a given shading device based on the shade it produces.

What is the formula for angle of elevation?

tan θ = y/x; cot θ = x/y. depending upon the data given in the question, corresponding formula is applied to find out the angle of elevation. Here SR is the height of man as ‘l’ units and height of pole to be considered will be (h – l) units. The line of sight in this case will be PS and angle of elevation will be ‘θ’.

How is shading device calculated?

To calculate the depth (d) of the horizontal shading device, multiply the obtained ratio (d/h) by the needed shading height (h). To calculate the protrusion (p) of the horizontal shading device, multiply the obtained ratio (p/h) by the needed shading height (h) for the selected hours (cut-off times).

What is vertical sun shading?

Vertical shadow angle The vertical shadow angle (VSA) is required for (or cast by) horizontal shading devices. It is the angle between the ground line and altitude of the sun.

How do you calculate solar angle?

The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter, and subtracting 15 degrees from your latitude during summer. For instance, if your latitude is 34°, the optimum tilt angle for your solar panels during winter will be 34 + 15 = 49°.

How do you calculate the length of a shadow?

L = h/ tan α Where, L = Length of the shadow. h = height of the object. α = angle of elevation of the sun.

How do you calculate shading?
