introduction to sun and architecture
solar geometry
understand the position and movement of sun + earth is to understand the concept of appropriate design for solar radiation and other climatic condition
important of solar study
sun position and movement different for each month
earth exist
earth rotate daily on axis through two celestial poles (north and south) that is perpendicular to the equator, but not perpendicular to the earth's orbit
earth's exist is tilted at 23.3 degrees from the plane of its orbit
solar geometry
shading devices strategized to block out unwanted solar radiation for specific periods of time
sun path diagram : the position of the sun can be calculated on a given day, date and position by mathematical or graphical use of sun path diagram
position of the sun
the angle of altitude : is the angle between the horizontal plane and the earth sun line
angle range between 0 and 90 above the horizon depends on time date and location
altitude 0 means the sun has not yet risen
angle of azimuth : is in between the north and the actual direction of the sun
angle can range can from 0 to 180
0 angle of azimuth indicates the sun is directly due north
zenith : point in sky vertically above observer
altitude : angle height of sun above the horizon
line. it is easiest to calculate at solar noon when it is exactly north
azimuth : angle on plan between north and the actual direction of the sun at any time
horizon : line at which the plane of an observer intersects with the sphere of the sky

plane of sun
autumnal equinox ( September 23 )
summer solstice ( June 21)
winter solstice ( December 21)
vernal equinox (march 21)
building orientation and form are affected by the relationship of the sun and the earth
in design knowledge on sun position enables the predictions of
building shadow cast
building faces are sunlit
solar radiation direction and intensity
sunlight patches
case study
