SOLAR ENERGY AND PASSIVE
SOLAR HEATING
• The sun is a medium sized star that radiates energy
from nuclear fusion reactions in its core.
• The small fraction of energy from the sun is enough
power the wind, plant growth, and the water cycle.
• All the renewable energy comes directly or
indirectly from the sun.
• We use direct solar energy everyday.
• When the sun shines in your window and heats up
your room by solar power.
• Passive solar heating uses the sun energy to heat
something directly.
• The south facing windows receives the most solar
energy, so passive solar building have large
windows that face the south.
• Passive solar buildings must be well insulated win
thick walls and floors in order to prevent heat loss
• In the summer the sun’s path is high in the sky ant
the overhang of the roof shades the building and
keep it cool
• In the winter she sun’s path is lower in the sky and
the sunshine in your house which warms it
• A average house hold can reduce energy bills by
using passive solar energy
