- Green building refers to structures that are environmentally responsible and efficient in their resource use throughout construction and use.
- Buildings account for large portions of energy use, water use, and carbon emissions. Green building aims to reduce these environmental impacts.
- Key aspects of green building include using renewable energy like solar power, efficient water harvesting and use, recycled and sustainable materials, and reducing waste and pollution.
- Taipei 101 is an example of one of the largest and tallest green buildings in the world.
- Benefits of green building include reduced operating costs, conservation of natural resources, and improved health and productivity for occupants.

2. •
Green building (also known as green construction or sustainable
building) refers to both a structure and the using of processes that
are environmentally responsible and resource-efficient throughout a
building's life-cycle: from sitting to design, construction, operation,
maintenance, renovation, and demolition.[ In other words, green
building design involves finding the balance between homebuilding
and the sustainable environment.
3. Why Green Building?
According to the US green building council (USGBC):
1. Building accounts 38% of the CO2 emission in US.
2. Building consumes 70% of the electricity load in US.
3. 15 million new buildings are projected to be built this
year(2015).
4. Of the 26 billion gallon of water consumed in US each day
buildings use 13%.
5. About 8% of U.S . energy demand goes to treating ,
heating and pumping of water.
4. Environmentally regenerative
Focus on all five elements of Green Building: Energy ,
Water , Waste , Material , Habitat.
Restore the land.
Live green: beyond design and construction,
conservation and efficiency are a daily way of life.
Fit seamlessly into the environment.
6. Green the construction
process
Deconstruction of existing home for reuse and recycling,
90% recycled.
Recycled 98% of construction waste.
Replace conventional materials with environmentally
preferable alternatives.
Balanced cut and fill. No import/export of dirt.
Green concrete: Portland cement is responsible for 8% of
the CO2 emissions of the world. Replace 50-60% of
Portland cement with slag/fly ash.
No copper or PVC should be used anywhere onsite, other
than some wiring and small parts.
No asphalt , pine resin based driveway.
9. ENERGY
No lights are needed until
its dark.
100% LED or CFL. No
incandescent.
Wireless A/V control
system & dashboard to
manage home energy and
provide information.
10. ENERGY
Net zero energy, zero carbon emission
Combination super efficiency (reduce need
for power first) plus 21 kilo watt solar power
and 18 geothermal bores make house and
life style net zero.
radiant heating
fossil fuel should be avoided in domestic
purpose, no natural gas even piped onsite.
11. Enough solar to power five electric vehicles and still be
net zero energy
Solar energy is the sustainable energy. The building should use solar
power in all aspects to be environment friendly.
13. Materials
Wood:
100% FSC certified- five species.
Reclaimed or recycled.
salvaged
Metal:
Scrap recycled bronze, wrought iron, and recycled
metals used for railing , window hardware , roof ,
furniture , kitchen hood, and fixtures.
14. Materials
Stone:
100% reclaimed or recycled.
no newly quarried except for kitchen counters.
salvaged.
Glass:
super high tech serious windows.
recycled and recyclable.
15. Materials
Zero painted surface:
Natural lime plaster in children’s
bedrooms and bathrooms demonstrating
sustainable method for achieving colour.
Natural Tung oil in wet areas to protect
wood.
16. Water
Water goals:
o Use zero city water other than in our
taps.
o Extreme low flow fixtures.
o water conservation: real time
metering , monitoring and reporting.
o Repurpose one drop of rain water four
times.
o Using rain water instead of municipal
water in case of irrigation.
o Use treated waste water instead of
municipal water for irrigation.
o Employing subsurface drip instead of
overhead sprinklers.
17. Rain water harvesting
Building should be able to harvest
rain water.
In every there should be a
arrangement to catch the rain
water.
The rain water should be used in
many domestic purposes such as in
bathrooms . For watering the
garden etc.
Harvesting rain water will lead us
to environmentally economical. It
will reduce the power consumption
, it will save the municipal water.
18. Waste
• Reduce , Recycle , Recycle:
Recycling bins easily
accessible all over the house.
Garbage disposal feed
subsurface irrigation.
Composting on site.
Chickens eat scraps provide
fertiliser for organic garden.
19. A Pebble in a pond, one house can’t make a
difference, but together we can ......... Thank you
for being the part of the ripple effect helping
make the world a better place....
