INTRODUCTION
3
WHAT IS PASSIVE SOLAR BULIDING?

• A passive solar home means a comfortable home
  that gets at least part of its heating, cooling,
  and lighting energy from the sun.

4
HOW TO MAKE A PASSIVE SOLAR BUILDING

• It is designed to use the energy of sun. Its
  material and building works together to create
  energy.
• THINGS WE NEEDED-
• Large windows
• Solid wall
• Water
• Fans
• Overhangs.

5
PASSIVE SOLAR BUILDING IDEAS

• APERTURE Large window expansion that allows sun
  energy, it faced south, made improvements in more
  low cost.
• THERMAL MASS It is a construction material which
  stores or collect energy from sun.
• INSULATION Once power of the sun is collected,
  it should not be waste. So, it eliminates the air
  leak around the building.
• DISTRIBUTION Helps to circulate the stored
  solar energy when needed.

6
BENEFITS OF PASSIVE SOLAR BUILDING

• INVESTMENT Independent from future fuel cost,
  save money long after initial cost recovery.
• VALUE High owner satisfaction and resale value.
• MAINTENANCE Reduced operation and repair.
• COMFORT No operating noise, act as warmer and
  cooler according to the climate(even in power
  failure).

7
WHY PASSIVE SOLAR BULIDING NECESSARY?

• Passive solar design save energy by maximizing
  the homes natural heating.
• Passive solar building design very important role
  in reducing the greenhouse emissions in our
  society.
• Creating passive solar building to save energy
  which voluntary comply with openings are also
  important compliments to passive heating
  cooling.

8
DIFFERENCES FROM ORDINARY BUILDING PASSIVE
SOLAR BUILDING

• Passive solar building designThese standards are
  much higher then houses built to most normal
  building.
• About 15 space heating in an ordinary home comes
  from solar energy passive solar houses are
  designed to let heat into the building during the
  wintersimple huge difference in comfort
• The building it self server as solar collector
  storage device where as ordinary building not
  like that.

9
FEATURES OF PASSIVE SOLAR BUILDING

• It uses the basic design to trap heat when
  needed.
• So, it keep the house cool in summer and hot in
  winter.
• It picks up lot of free heat in winter from
  sunlight(contains about a kW of heat).

10
ACTIVE SOLAR

• Active solar technologies are employed to
  converts into solar energy another more useful
  form of energy.
• This would normally be a conversion to heat or
  electrical energy.
• Active solar uses electrical or mechanical
  equipment for this conversion.
• Passive solar relies on the inherent
  thermo-dynamic properties of the system or
  materials to operate.
• They do not need external energy source.

11
ENERGY-PLUS-HOUSE

• An energy-plus-house produces more energy from
  renewable energy sources, over the course of a
  year, than it imports from external sources.
• This is achieved using a combination of micro
  generation technology and low-energy building
  techniques, such as passive solar building
  design and careful site selection and placement.
• A reduction of modern conveniences can also
  contribute to energy savings, however many
  energy-plus houses are almost indistinguishable
  from a traditional home, preferring instead to
  use highly energy-efficient appliances, fixtures,
  etc., throughout the house

12
ZERO ENERGY BUILDING

• A zero-energy building(ZEB) or net energy (ZNE)
  building general term applied a building with
  zero net energy (ZNE) consumption and zero carbon
  emission annually.
• Reduce carbon emissions and reduce dependence on
  fossil fuels
• zero energy buildings remain uncommon even in
  developed countries, they are gaining importance
  and popularity.

13
DEVELOPMENT OF ZERO ENERGY BUILDING (ZEB)

• No ZEB regulations or standards
• Existing Energy Conservation Program
• Existing Green Building Label System

14
EFFICIENCY AND SOLAR ZEB

• First efficiency,
• then solar
• Together, they can
• make a big difference.
• Super-efficient solar
• Zero Energy Building.

15
WHY NET ZERO IS IMPORTEN

• Buildings are the Largest Energy Consumer in the
  U.S. 40 of primary energy, 72 of electricity,
  55 of natural gas.

16
WHAT ARE THE ADVANDAGES OF GOING ZERO ENERGY

• Money Savings (gt1,000s/year)
• Greater comfort.
• Better quality of life, more free time, more
  money.
• Less use, Less maintenance.
• Longer lasting heating and cooling equipment.

17
ADVANCING NET-ZERO ENERGY COMMERCIAL BUILDINGS

• In the United States, buildings account for
  almost 40 of primary energy use and greenhouse
  gas emissions.
• Energy use will help address climate change and
  extend the life of our national resources.
• Has set a goal to achieve cost-effective,
  net-zero energy commercial buildings in all U.S.
  climate zones by 2020.
• Renewable Energy Laboratory (NREL) leads the way
  in net-zero energy building (NZEB) innovation.

18
SUMMARY

• Can achieve zero energy home now
• Design for efficiency and solar up-front.
• Super high level of energy efficiency.
• Encourage conservation of residents.
• Choose solar thermal for water and pool heating.
• Use small PV systems of 4kW or so (this is still
  not cost effective at present electric rates
  without subsidies).
• Consider some PV on West side to reduce utility
  peak.
• Watch your meter spin backwards!!!!!

19
MY NET-ZERO ENERGY HOUSE(ALSO ZERO EMISSION
HOUSE)

• This house will save a projected 165,000 in fuel
  and energy cost.
• Over the next 20 years.

20
NEXT GENERATION ZERO ENERGY RESEARCH HOME
21
CONCLUSION

• We are saw about how to
• save energy.
• In this way we are follow
• to reduce usage of
• electricity.
• It will be help us and also
• our Future generation.
