Introduction:
In the thermal design of buildings, the aspects of
climate of immediate interest are thermal primary radiation, temperature, humidity and
wind. Together with precipitation are linked into a global system which is the result of
the constant radiation of energy from the sun and the 24-h rotation of the earth about its
axis and the 12-month rotation around the sun.
Thus radiation and planetary movement in the solar system are the prime movers of the
earth's system of mass and energy flow.
This unit introduces the fundamentals of solar radiation and its basic influence about the
built environment. Upon completion of this unit, you should be able to understand:
a) The physics of solar
radiation
b) Sun movement
c) Solar angle determination
d) Angle of incidence, and
e) Solar intensity
In this unit, there are five chapters related to the solar radiation, Go and see, you can have more understanding about this subject.
