How do we know what direction the wind is blowing from?
The way a weather vane is pointed by prevailing winds indicates the direction from which the wind is blowing. Modern instruments used to measure wind speed and direction are called anemometers and wind vanes, respectively.
What does wind west mean?
A “west wind” is coming from the west and blowing toward the east. A “south wind” is coming from the south and blowing toward the north.
How does wind direction affect architecture?
Wind direction, frequency and speed will influence the building design including weather tightness detailing, entry locations, size and placement of windows, selection of roof and wall cladding, bracing requirements, and provision of shelter in outdoor spaces. …
Why is it important to determine the sun path and wind path of the chosen site?
Assessing the passage of sun across a site is important. Sun path diagrams provide a broader overview of sun on a site as they map the path of the sun across the sky at different times during the day throughout the year.
Why is wind analysis important?
Wind load analysis is critical to ensure that the following criteria are honoured: Stability to counter toppling, uplift or sliding of the building. Strong structural components to withstand excess loads during the building’s life cycle. Serviceability of the building, despite expected wind deflections.
Why is sun path important?
The Sun’s path affects the length of daytime experienced and amount of daylight received along a certain latitude during a given season. The relative position of the Sun is a major factor in the heat gain of buildings and in the performance of solar energy systems.
What direction does the sun set?
We usually speak of the sun setting in the west, but technically it only sets due west at the spring and autumn equinoxes. For the rest of the year, the direction of sunset pivots about this westerly point, moving northerly in winter, and towards the south in summer.
