Passive Solar Energy

2. Defining Passive solar energy
Passive solar design refers to the use of the sun’s energy for the heating and cooling of living spaces. In this approach, the building itself, or some element of it, takes advantage of natural energy characteristics in materials and air created by exposure to the sun.
Simple, few moving parts, and require minimal maintenance
No mechanical systems.

3. Uses of passive solar energy
The main use of passive solar energy
Cooling
Heating
without the use of Electricity, Oil, or any other pricey method.

4. Passive energy in History
Was used over 2500 years
Greece
Cities
Streets
East-west, and North-south
Sheltered the north
Rome
“Sun Furnace”
mica or glass

5. In history continued The English Dutch South facing green houses
Exotic plants in winter
Night time canvas covers

6. “appliances”
The main focus is on the use of glass. Glass allows light in but traps heat, known as the greenhouse effect.
A trombe wall
thick, south-facing wall
painted black
Heat absorbing material
Clerestory
north-facing rooms and upper levels,
a row of windows
near the peak of the roof
Overhangs
Ventilation
Masonry and concrete
minimum of 4 inches thick.

7. How passive solar power works
Direct gain design - A direct gain design collects and stores heat during the day.  At night stored heat is radiated into the living spaces.
Direct gain interior - A direct gain design with an interior water wall for heat storage.  Heat stored in the water wall is radiated into the living space at night.

8. Building plan
Interior space should be arranged so that rooms with high heating
and lighting requirements are arrayed along the south wall.

9. Cooling Summer’s can become unbearably hot
Windows on the higher floors
Allows air to escape naturally
Windows on the lower floors
Allows cool breezes to enter

10. Cooling
Locate cool air inlet vent on the building side which receives predominant cool summer breezes
To aid in natural ventilation, during summer use high ceiling vaults, and thermal chimneys to promote rapid air changes.

11. Where is solar power used
Any home will benefit from passive solar energy as long as there is sun light.
Best places:
Places with sunlight, and colder nights.
Places near the equator.
Areas to avoid passive solar energy would be:
Places that have little or no sunlight for long periods of time.

12. Why Passive Solar Power
Once you set up a passive solar system the energy you receive is free.
Maintenance
50% lower energy bills
The architecture
Large windows
cathedral-like floor plans

13. “Climate Design” Important steps to remember Building orientation
Proper window sizing and placement
Roof overhangs 
Thermal energy storage mass (masonry tiles)
Absorbers
Aperture or collector (glass)

14. How Passive energy will reduce the use of Fossil Fuels
Generally, the amount of solar energy that falls on the roof of a house is more than the total energy used within the house.
does not always mean the elimination of mechanical systems, although recent designs back-up heating systems
greatly reduce traditional heating systems and amount of non-renewable fuels needed to maintain comfortable indoor temperatures.

16. Conclusion
The fuels that Passive Solar Energy will save, will have a positive effect on our environment.
Cheaper than most other energies
Easy to maintain
Helps keep our plant healthy
