Understanding

sun-path diagram

Chapter 4

LEARNINGS –

• By studying the sun-path diagram of a place
one can identify the optimal orientation of
solar panels in a given building.
• . By identifying the solar-windows of a
particular location, one can design the
building such that there is maximum utility of
the solar energy by placing thermal mass
required for indirect heat gain in the right
orientation.
• By tracing down the surface area illuminated,
to the greatest extent, by the sun, the location
of clerestories and fenestrations of a building
can be optimized so that the thermal and
visual comfort levels in the building are met. •
The shading devices also can be designed
similarly.

• Coming to one of the most important uses,
the location of the house so that it receives the
maximum shade during summer can be
obtained
