1. By: William Andrew Meyers Elizabeth Rachel Selvaggio Camerdon Patrick Valade PASSIVE SOLAR ENERGY

2. Uses and Functions  USES & FUNCTIONS HEATING ELECTRICITY COOLING HOT WATER

3. Producing Energy -Heating:  Sun space- its built on a side wall of a building, sunlight passes through and warms it. It’s made of material that absorbs heat, and proper ventilation allows heat to circulate into the building during the day and warms it at night -Electricity: Photovoltaic- the panel consist of solar cells that transform the energy from the sun to electricity. 1 Panel= A 12V Battery

4. PRODUCING ENERGY -Cooling: ► Thermally Activated Cooling Systems (TACS) ► Driven by solar energy, and sized to provided 30%-60% of building cooling requirements. ► The Refrigerant is condensed, throttled and evaporated to yield a cooling effect, which is reabsorbed to continue the cycle. BADGOOD

5. -Hot Water:  Integrated Collector and Storage Systems: It’s a water holding tank in a box, with glass on the side facing south. They start with 40 Gallons and are panted black with high temperature engine.

6. ADVANTAGE ► Saves you money. $$ ► Does not require any fuel. ► Is not affected by supply and demand, so prices will never increase. ► Passive Solar energy is clean, renewable and sustainable. ► Contributes to the decrease of harmful green house gases.

7. ADVANTAGES CONT’D ► Can operate entirely independent. ► Reduces our dependence on foreign sources of energy. ► Continues to supply your home in the event of a power outage. ► Maintenance Free! ► Lasts for decades!

8. What Can it Replace -Passive Solar Energy could replace our most dependent non-renewable resources such as Oil and Coal. -If you were to retrofit your home with solar panels and design the home to be naturally heated (Picture) you could run everything in your home, or at the very least cut down on your use of fossil fuels.

9. WHERE IS IT USED? Passive Solar Energy is being used all over the United States, as people become more aware of this technology and design. Pro’s- better for environment, cheaper, a renewable and sustainable energy source. Con’s- In some cases the materials necessary for passive solar energy may be somewhat expensive.

10. Challenges of Making it Mainstream The government would need to make standards for more efficient houses using passive solar materials and designs. Need to make passive solar materials cheaper and needs to be advertised more to make people realize they have options. Need to make inefficient products harder to get and tax the people who have inefficient houses.

11. Will it be mainstream? ► It is quiet possible to make passive solar energy mainstream, as long as the Gov. and Companies take the right steps, such as; ► More well known ► Easier to come by ► Cheaper

12.  Materials: -House (elongated on a east-west axis) -Shades -South Facing Glass -Thermal Storage Walls -Roof Pond System (for cooling) -Sun Rooms (Lets heat out in summer) -Efficient Window Seals -Solar Panels -Passive Solar Landscape Designs
