- 2. ABSTRACT • Passive solarenergy is an excellent idea to heat,cool and lightning the living room based on the structure of our buildings. • Passive solar energy is used to distribute heat or cool through wise selection of building materials. • Passive solar energy will provide inexpensive sustainable alternatives for heating and cooling of home.
- 3. INTRODUCTION Passive solarsystem is used to “collect, store and distribute thermal energy”-by means of conduction, convection and radiation. Decrease the amount of money that we spend on energy. The exploitation and misuse of natural resources rapidly depleting the Non-renewable energy resources. Passive solar energy buildings considerably reduces the usage of Non-renewable energy resources.
- 4. WIDE RANGE OFAVAILABILITY Solar energy can be utilized in various ways-to provide electricity, mechanical power, heat and lightning. Solar benefits are utilized through windows and pumps, and fans. Renewable energy resource and it meets future obstacles for scarcity of electricity.
- 5. NON-RENEWABLE ENERGY RESOURCES coal-250years oil-44years nuclearfuel- 23years By analysing the pie-chart there is little possibilities for our sustainability to meet our future.
- 6. WHY PASSIVE? Passivemeets the minimum requirements. Active produce the green house gases such as (CO2). Active solar energy is expensive and more equipments are need for installation.
- 7. PASSIVE SOLAR HEATING Passive solar heating happens when sunlight strikes an object and that object absorbs the heat. Effective when the windows are oriented correctly, Perfect orientation is south. By installing high performance windows with insulated frames, multiple glazing, low-e-coatings we may reduce the heat loss by 50 to 75 percent.
- 8. PASSIVE COOLING Buildingsare designed to retain cooling and drew the heat air away. The shading device is fixed and this was achieved by natural vegetation and using special glazing in windows. The shading device can reduce solar gains up to 90%.
- 9. MATERIALS REQUIRED Acrylicglasses or panels is enough to observe the heat from the sunlight ,used as windows and doors Normal concrete was just enough to make the thermal mass, these are act as a absorber.

- 11. CATEGORIES OF PASSIVESOLAR ENERGY Direct gain method Indirect gain method Isolated gain method
- 12. DIRECT GAIN Directgain method is the simplest method where the space of the building is directly heated by sunlight.
- 13. INDIRECT GAIN Forindirect gain,sunlight is often received by a south facing wall,and as air moves internal space the heat moves through the living room.
- 14. ISOLATED GAIN Isolatedgain method contains solar collection,thermal storage that are separated from actual living space.

- 17. ADVANTAGES Mainly itprovide perfect temperature and it is renewable energy resource. It’s cost of installation is lower than active solar energy resources. And it is eco friendly due to the eradication of green house effect. Less or zero usage of conventional equipments.
- 18. FUTURE TRENDS Thedesign of passive solar buildings based on the materials are available today and will consistent for next several decades. Many obstacles due to over exploitation of non- renewable resources may be eradicated by using this energy.
- 19. CONCLUSION Solar energyhas been used for centuries and has only improved with time, as scientists and researchers made it into effective way of uses. Passive solar energy is a very cost efficient way to take steps towards sustainability.
