Green building aims to create energy-efficient, healthy buildings with minimal environmental impact. There is a global push by governments and organizations to improve sustainability and livability through green building. Green buildings provide cost benefits like reduced operating costs and incentives, and have competitive advantages. Standards like LEED rate buildings on sustainability factors like energy use, materials, and indoor environmental quality. The presentation discusses green building strategies, technologies, benefits and certification systems.

2. Green building is a high performance building design concept
that aims at creating energy-efficient ,healthy and productive
building with minimal impact on the local environment.
A global drive in construction industry worldwide by various
national governments and international entities for improving
the environmental conditions, sustainability and urban livability.
They are real, pragmatic solutions to vexing problems
associated with climate change, human health and
environmental quality for sustainable living.

5. The LEED stands for Leadership in Energy and
Environmental Design .
The LEED rating is a form of eco-label that rates buildings
according to key environmental attributes such as site
impacts, energy and water use, selection of materials and
indoor environmental quality.

6. The United States Green Building Council (USGBC) has
developed LEED rating system for meeting specific set of
standards for green buildings.
Certified 40-49 points
Silver 50-59 points.
Gold 60-79 points.
Platinum ≥ 80 points.

11. Answer is No.
Because of indiscriminate use of concrete and conventional
building materials in urban areas ,the normal atmospheric
temperature is relatively higher than areas with few buildings.
CO2 emissions from such buildings add to the environmental
pollution and global warming which might result in
catastrophic consequences such as:
Reduction in agricultural output and global food
production.
Rise in the sea level in coastal plains.
Alteration in ecosystem and biodiversity pattern .
Prolonged flooding and copious rainfall in regions
receiving abundant rainfall.
6/3/2012 11

12. Higher upfront capital investment for usage of advanced
technologies and materials.
Lack of knowledge and experienced workforce.
Slow diffusion of technological know-how.
Deliberate negligence towards ecofriendly concerns.
Global economic slump and slow growth in new construction
projects.

13. Green landscaping strategy:
* Green site creation to harvest rainwater through minimization of runoff
loss and bioswales.
* Installation of pervious pavements around the building.
*Planting xerophytes around the building in order to minimize
supplemental irrigation.
Usage of high quality and sustainable building materials.
* Volatile organic compounds.
*Urea formaldehyde.
Culprits of health hazards .
*Particulate matter.
Sustainable roof options-Photovoltaic roofs.
Sustainable energy options.
Distributed energy resources.
Geothermal systems or ground source heat pumps.
Sustainable interiors. 13

15. 1. Adobe Systems Inc.
In 1999, Cushman and Wakefield a global real estate services
provider with a track record of sustainable building operations
undertook the green building renovation work at Adobe
Towers, San Jose ,CA
Adobe Systems Inc. has achieved 5 LEED certifications and 4
out of which are at platinum level.
Adobe realized a total savings of $ 1.2 M of which $ 98,000 per
year was in electricity costs savings.

18. Zero-Energy Buildings (ZEB) : In order to achieve net-zero-energy
use, building energy demand should be reduced by 60-90 % over
current standards and the remainder would be satisfied by on-site
renewable energy generation such as solar, wind and geothermal
technologies.
According to ,United States National Renewable Energy
Lab(NREL), ZEB produces as much energy as it uses when
measured at the site.(Net –zero site energy building).

19. Photovoltaics is a method of generating direct
current electricity by converting the solar radiation
of sun into electric energy by use of solar cells.

20. Eco-Cement : Eco-cement is a CO2 absorbing cement.
Usually Magnesia (MgO) is added to the normal Portland cement
in order to sequester the CO2 ,the main gas responsible for
environmental pollution and local warming effect .

23. Cool Wall contains specialized heat reflective pigments and
it can be used as an exterior paint for weather –ability .
Cool wall reflects the infra-red portion of
the sun’s rays ,keeping exterior surfaces cooler and allowing
less heat into the interior of the building.

24. The recent advances in nanotechnology ,information technology ,and
renewable energy technologies have created opportunities for energy-efficient
green buildings.
With growing demand for sustainable, eco-friendly and socially responsible
lifestyle has necessitated the construction of green buildings towards
achieving the goal of a greener planet in foreseeable future.
The global demand for retrofitting the existing building structures into green
building standards in accordance with Energy Star ,ISO 50001& LEED in
order to achieve the energy efficiency and sustainable environmental
standards is on rise.
This innovation in sustainable building technologies is not only a
benchmarking standards for next generation buildings but also safe practices
for curbing global warming and environmental pollution.
