Green building

2. A building designed to be ecologically correct by using resources efficiently, using internal recycling,
renewable energy sources, recyclable or biodegradable construction materials, and blending in with the
local environment, particularly in out-of-town locations. The aims are to reduce to a minimum the
environmental impact, and to take human health factors into consideration.
A green or sustainable building is a building that, because of its construction and features, can
maintain or improve the quality of life of the environment in which it is located. To do this, it is
essential to achieve a high level of efficiency: reducing the consumption of energy, water and other
resources minimises pollution. The LEED certificate (Leadership in Energy and Environmental Design) is
the internationally accepted official recognition that establishes whether a building deserves to be
considered sustainable.

3. To evaluate a building's sustainability, LEED certification establishes a points system based on various
sections, which we will review below, related to design and construction:
Location and transport Materials and resources
Sustainable sites Indoor environmental quality
Efficient use of water Design innovation
Energy and atmosphere Regional priority
3 PILLARS OF SUSTAINABILITY
Social: It refers to the human capital, as the creation of tools that
improve the citizens’ quality of life, laws to support the necessity
of the population and the development of improving politics in areas
like education, security and leisure. This pillar assumes that the
searching for a sustainable society has the idea of having a well-
cared and healthy society. Besides, it is important to provide an
environment that stimulates the legitimate and healthy work
relationship, in order to favour the personal and collective
development of all people involved.

4. Environmental: The environmental pillar has its roots on the many ways to search for the
environmental preservation, the natural resources and the diminishing of the damage caused to
the environment during the years. It is on this stage that the companies study the ways to
accomplish their operations causing the lowest possible impact to the environment.
Economic: It refers to subjects about production, distribution and consumption of goods and
services. To have sustainability, companies can not profit at the expense of work exploitation or
irresponsible and criminal exploitation of the environment. The financial area benefits from
sustainable attitudes, because they reduce materials, energy and water, reducing also their bill in
the end of the month. In other words, there is a cyclic process of benefits between
sustainability and economy.
What is sustainable development
Sustainable development can be defined as an approach to the
economic development of a country without compromising with
the quality of the environment for future generations. In the
name of economic development, the price of environmental
damage is paid in the form of land degradation, soil erosion, air
and water pollution, deforestation, etc. This damage may
surpass the advantages of having more quality output of goods
and services.

5. Sustainable Development Goals
• To promote the kind of development that minimises environmental problems.
• To meet the needs of the existing generation without compromising with the quality of the
environment for future generations.

6. Achieving Sustainable Development
Sustainable development can be achieved if we follow the following points:
• It can be achieved by restricting human activities.
• Technological development should be input effective and not input utilising.
• The rate of consumption should not surpass the rate of salvation.
• For renewable resources, the rate of consumption should not surpass the rate of
production of renewable substitutes.
• All types of pollution should be minimised.
• It can be achieved by sensible use of natural resources.
Examples of Sustainable Development
• Wind energy
• Solar energy
• Crop rotation
• Sustainable construction
• Efficient water fixtures
• Green space
• Sustainable forestry

7. Sustainable Architecture Strategies
Sustainable architecture is the use of design strategies that reduce the negative
environmental impact from a built environment. Architects take the site landscape, energy
management, and storm water management into consideration when planning, and then use
environmentally friendly systems and building materials during construction.
When designing public buildings with sustainability in mind, architects use the following top
five sustainable architecture strategies:
1. Passive Sustainable Design.
Passive strategies, such as considering sun orientation and climate when siting and being
thoughtful about window placement and operation, are used to best manage day lighting and
natural ventilation and go a long way in reducing energy requirements for the building. In
certain climates, thermal mass techniques can be used to harness solar energy. In such cases,
thick walls absorb heat from the sun during the day and release it into the building at night.
2. Active Sustainable Design.
Architects consult with mechanical and electrical engineers to implement high-efficiency
electrical, plumbing, HVAC, and other systems, which are designed to have small environmental
footprints.
3. Renewable Energy Systems.
Renewable energy systems, including those that harness solar and wind energy, are also great
options for some buildings. These systems are often used in conjunction with passive design
strategies.

8. 4. Green Building Materials and Finishes.
By making it a priority to purchase steel, lumber, concrete, and finishing materials, such as
carpet and furnishings, from companies that use environmentally responsible manufacturing
techniques or recycled materials, architects up the ante on sustainability.
5. Native Landscaping.
Landscaping choices can make a big impact in civic building water consumption. By using trees,
plants, and grasses that are native to the area, architects can greatly reduce irrigation needs.
Landscaping can also be used as part of a passive energy strategy. By planting trees that shade
the roof and windows during the hottest time of the day, solar heat gain inside the building can
be reduced.
6. Storm water Management.
When rain falls on an untouched site, the water that doesn’t evaporate absorbs back into the
ground, replenishing the natural water table. However, when a building is placed on the site,
along with parking lots, sidewalks, access roads, and other hardscaping, rainfall behaves
differently. The water runs off these surfaces and into storm drains. By implementing storm
water management strategies, such as pervious pavement that helps to reduce runoff and
retention ponds that capture runoff and slowly release water back into the ground, the
negative environmental impact of buildings can be reduced.

9. ITC Green Centre, Gurgaon
ITC Green Centre has received the prestigious LEED certification by USGBC-LEED. With green
and sustainable building techniques used during the construction phase, ITC Green Centre has
managed to reduce its energy consumption significantly. Double glazed windows do not allow heat
to enter the building and double gaze insulation regulates temperature in the building.
Highlights of the building
•Use of glass which has 19% recycled content helped ITC to get points in recycle
content.
•Use of other recycled and recyclable resources, with materials like fly ash based
cement etc. more than 10% of the building materials used are recycled, refurbished
or salvaged from other sites
•40% of the total raw materials used were procured within 500 miles of the project
site such as double glazed glass façade and window framing, 250mm thick auto-
claved and aerated concrete block wall
•Daylight and views: views to external glazing from at least 90% of regularly
occupied areas
•Use of solar photo voltaic for emergency lighting
•Use of green material to reduce heat gain from rooftop / building envelope with
high performance glazing and proper insulation material CFC/HCFC free HVAC
equipment is used to combat ozone depletion.

10. •Installation of solar hot water system and solar concentrator for kitchen
•Use of green material to reduce heat gain from rooftop / side walls. low cost
version of this idea is to paint the rooftop white or roll out gunny bags in summer

atmosphere).

11. Jawaharlal Nehru Bhawan, New Delhi
The office of Ministry of External Affairs, Jawaharlal Nehru Bhawan is designed in sync with the
environment and its surroundings. The external design of the building is derived from Lutyen’s era
while the interior is completely state-of-the-art. Insulated walls keep the building cool in summers
and reduce air conditioning requirements by 30%. Reflecting panels do not let the building get
heated in summers while keeping it warm in winters. Efficient waste management and recycling
account for better resource management. CFLs have been installed along with vertical gardens
giving the building a distinct look.
