3. A passive solar home means a comfortable home
that gets at least part of its heating, cooling, and
lighting energy from the sun.
4. It is designed to use the energy of sun. It’s
material and building works together to create
energy.
LARGE WINDOWS
SOLID WALL
WATER
FANS
OVERHANGS.
5. Large window expansion that allows
sun energy, it faced south, made improvements
in more low cost.
It is a construction material
which stores or collect energy from sun.
Once power of the sun is collected,
it should not be waste. So, it eliminates the air
leak around the building.
Helps to circulate the stored
solar energy when needed.
6. Independent from future fuel cost,
save money long after initial cost recovery.
High owner satisfaction and resale
value.
Reduced operation and repair.
No operating noise, act as warmer
and cooler according to the climate even in
power failure .
7. 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. Passive solar building design…These 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
winter…simple huge difference in comfort
The building it self server as solar collector &
storage device where as ordinary building not
like that.
9. 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 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. 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. 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. No ZEB regulations or standards
Existing Energy Conservation Program
Existing Green Building Label System
15. Buildings are the Largest Energy Consumer in the
U.S. 40% of primary energy, 72% of electricity, 55%
of natural gas.
16. Money Savings (>$1,000s/year)
Greater comfort.
Better quality of life, more free time, more money.
Less use, Less maintenance.
Longer lasting heating and cooling equipment.
17. 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 .
Renewable Energy Laboratory (NREL) leads the
way in net-zero energy building (NZEB)
innovation.
18. 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. This house will save a projected $165,000 in fuel
and energy cost.
Over the next 20 years.
20.
21. 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.
