Green building (also known as green construction or sustainable building) refers to both a assembly and the using of progressions that are environmentally responsible and resource-efficient throughout a building's life-cycle: from siting to design, construction, process, conservation, renovation, and demolition. In extra words, green building design contains finding the balance between homebuilding and the sustainable environment. This requires close collaboration of the design team, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort.A similar concept is natural building, which is usually on a smaller scale and tends to focus on the use of natural materials that are available locally. Other related topics include sustainable design and green architecture. Sustainability may be defined as meeting the needs of present generations without compromising the ability of future generations to meet their needs. Although some green building programs don't address the issue of the retrofitting existing homes, others do, especially through public schemes for energy efficient refurbishment. Green construction principles can easily be applied to retrofit work as well as new construction.

2. INTRODUCTION
The ‘GREEN BUILDING’ concept is gaining importance in various countries, including
India. These are buildings that ensure waste is minimized at every stage during the
construction and operation of the building, resulting in low costs, according to experts in
technology. A Green building is a structure that is environmentally responsible and
resource efficient throughout its life cycle. 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 siting to design, construction, operation, maintenance,
renovation, and demolition. In other words, green building design involves finding the
balance between homebuilding and the sustainable environment. This requires close
cooperation of the design team, the architects, the engineers, and the client at all
project stages The Green Building practice expands and complements the classical
Although new technologies are constantly being developed to complement current
practices in creating greener structures, the common objective of green buildings is to
reduce the overall impact of the built environment on human health and the natural
environment by:
 Efficiently using energy, water, and other resources
 Protecting occupant health and improving employee productivity
 Reducing waste, pollution and environmental degradation[3]
building design concerns of economy, utility, durability, and comfort.

3. DESIGN EFFICIENCY
 The foundation of any construction project is rooted in the concept and design
stages. The concept stage, in fact, is one of the major steps in a project life cycle,
as it has the largest impact on cost and performance. In designing
environmentally optimal buildings, the objective is to minimize the total
environmental impact associated with all life-cycle stages of the building project.
However, building as a process is not as streamlined as an industrial process,
and varies from one building to the other, never repeating itself identically. In
addition, buildings are much more complex products, composed of a multitude of
materials and components each constituting various design variables to be
decided at the design stage. A variation of every design variable may affect the
environment during all the building's relevant life-cycle stages.
ENERGY EFFICIENT
 To reduce operating energy use, high-efficiency windows and insulation in walls,
ceilings, and floors increase the efficiency of the building envelope, (the barrier
between conditioned and unconditioned space). Another strategy, passive solar
building design, is often implemented in low-energy homes. Designers orient
windows and walls and place awnings, porches, and trees to shade windows and
roofs during the summer while maximizing solar gain in the winter. In addition,
effective window placement (day lighting) can provide more natural light and
lessen the need for electric lighting during the day. Solar water heating further
reduces energy costs.
 Onsite generation of renewable energy through solar power, wind power, hydro
power, or biomass can significantly reduce the environmental impact of the
building. Power generation is generally the most expensive feature to add to a
building.

 Onsite generation of renewable energy through solar power, wind power, hydro
power, or biomass can significantly reduce the environmental impact of the
building. Power generation is generally the most expensive feature to add to a
building.
 Green building materials are composed of renewable, rather than nonrenewable
resources. Green materials are environmentally responsible because impacts are
considered over the life of the product. Depending upon project-specific goals, an
assessment of green materials may involve an evaluation of one or more of the
criteria listed below.
Green building material/product selection criteria :
 Resource efficiency
 Indoor air quality
 Energy efficiency
 Water conservation
 Affordability
RESOURCE EFFICIENT
 Recycled Content: Products with identifiable recycled content, including
postindustrial content with a preference for post-consumer content.
 Resource efficient manufacturing process: Products manufactured with
resource-efficient processes including reducing energy consumption, minimizing
waste (recycled, recyclable and or source reduced product packaging), and
reducing greenhouse gases.
 Locally available: Building materials, components, and systems found locally or
regionally saving energy and resources in transportation to the project site.
 Durable: Materials that are longer lasting or are comparable to conventional
products with long life expectancies.

5. HOUSEHOLD MODEL FOR GREENARY SUSTABINILITY
 Indoor Air Quality seeks to reduce volatile organic compounds, or VOCs, and
other air impurities such as microbial contaminants. Buildings rely on a properly
designed ventilation system (passively/naturally- or mechanically-powered) to
provide adequate ventilation of cleaner air from outdoors or recirculated, filtered
air as well as isolated operations (kitchens, dry cleaners, etc.) from other
occupancies.
 Low or non-toxic: Materials that emit few or no carcinogens, reproductive
toxicants, or irritants as demonstrated by the manufacturer through appropriate
testing.
 Moisture resistant: Products and systems that resist moisture or inhibit the
growth of biological contaminants in buildings.
 Systems or equipment: Products that promote healthy IAQ by identifying indoor
air pollutants or enhancing the air quality.

6. OPERATION AND MAINTAINCE OPTIMIZATION
No matter how sustainable a building may have been in its design and construction,
it can only remain so if it is operated responsibly and maintained properly.. Every
aspect of green building is integrated into the O&M phase of a Ensuring operations
and maintenance(O&M) personnel are part of the project's planning and
development process will help retain the green criteria designed at the onset of the
project building's life. The addition of new green technologies also falls on the O&M
staff. Although the goal of waste reduction may be applied during the design,
construction and demolition phases of a building's life-cycle, it is in the O&M phase
that green practices such as recycling and air quality enhancement take place
 Green architecture also seeks to reduce waste of energy, water and materials
used during construction. For example, in California nearly 60% of the state's
waste comes from commercial buildings .During the construction phase, one goal
should be to reduce the amount of material going to landfills. Well-designed
buildings also help reduce the amount of waste generated by the occupants as
well, by providing on-site solutions such as compost bins to reduce matter going
to landfills.
 To reduce the impact on wells or water treatment plants, several options exist.
"Greywater", wastewater from sources such as dishwashing or washing
machines, can be used for subsurface irrigation, or if treated, for non-potable
purposes, e.g., to flush toilets and wash cars. Rainwater collectors are used for
similar purposes.
 Centralized wastewater treatment systems can be costly and use a lot of energy.
An alternative to this process is converting waste and wastewater into fertilizer,
which avoids these costs and shows other benefits.
 Develop and implement a waste management policy for building operation, including
an initial waste generation and recycling assessment, targets for recycling rates,
occupant incentives, and verification on an annual basis as to whether reduction
goals are being met. The following materials should be targeted for recycling in the
policy: consumer products (e.g. computers, electronic equipment, office supplies,
plastics, glass, paper, aluminum); routine maintenance items (e.g. fluorescent and
HID lamps) and items from renovation (e.g. acoustical ceiling tiles, carpet tiles, and
furniture).
 Adopt green meeting practices. Evaluate potential hotel and conference center
venues that are sustainable in that they recycle, purchase recycled or recyclable
items, use nondisposable food and beverage service, have bottle deposits, a plan for
leftover food and meeting materials, and practice water and energy conservation.
 Require cleaning contractors to implement green cleaning practices including and not
limited to using resources for recycled content paper stock and trash liners,
environmentally friendly cleaning products, and vacuum cleaners with filtration systems

7.  Use cleaning products that meet Green Seal Standard GS-37, products with low volatile
organic compound (VOC) levels and products with high post-consumer recycled content
HOW TO MAKE GREEN HOMES
The Indian Green Building Council (IGBC), was formed in the year 2001 by
Confederation of Indian Industry (CII). The vision of the council is to usher in a green
building movement in India and facilitate India to become one of the global leaders in
green buildings by 2015.
 With a modest beginning of 20,000 sq. ft. (1,900 m2). green built-up area in the
country in the year 2003, today more than 1053 green buildings ( as on April
2011) with a built-up area of over 648,000,000 sq. ft. (60,200,000 m2). are being
constructed all over India, of which 147 green buildings are certified and fully
functional
