2. Sun path refers to;
-- seasonal-and-hourly positional change
of Sun and length of daylight as
Earth rotates and orbits around the sun.
Accurate location/specific knowledge of sun path and
climatic conditions essential for:
• economic decisions about solar collector area
• orientation,
• landscaping
• summer shading, and
• cost-effective use of solar trackers.

3. • Sun paths at any latitude and any time of the
year can be determined from basic geometry.
• The Earth's axis of rotation tilts about 23.5
degrees, relative to the plane of Earth's solar
system orbit around the Sun.
• As the Earth orbits the Sun,
creates the 47-degree peak-to-peak solar
altitude angle difference, and
hemisphere-specific difference between summer
and winter.

7. • Sun does not touches the North Side in the
Northern Hemisphere- Sun rises in East and sets
in West with variations in Summer and Winter
• No direct solar radiation available on the
Northern Side
• However, daylight available during the entire
duration of the sun in North

8. • Daylight remains uniform in North - depending on
sky conditions
• Coolest side with no direct Sun
• Best for work places which require enough light but
no heat
• North light is generally used in Industrial buildings/
drawing studio
• Courtyards should not be given in north side , as no
direct sun is available here.

9. • Solar Radiation available- both in Summer and
Winter
• In winter - Sun angle remains low- less duration
of Sun- 9 hrs
• In Summer-- Sun angle is high- Large duration of
Sun- 14 Hrs
• Maximum Solar radiation available on the
Southern Side

10. • In Winter Sun remains on the South for Majority of time
• Sufficient daylight available during the entire duration
of sun
• Being very hot and having glare in Summer – Southern
side have to be carefully handled.
• Summer Sun being very hot and vertical- can be
managed by horizontal projections.
• Winter Sun being low can be effectively used for making
rooms warm

11. • Southern side can be used for living and working
areas- bedrooms, dining, kitchen, offices etc .
• In the southern hemisphere, however, it is opposite, with
the windows facing the north in order to maximize solar
gain
