Why Are Green Buildings Needed?
Attaining environmental sustainability is a serious challenge facing the world
in the present scenario.
As the world is inching towards zero energy and non-contaminating buildings,
green building constructions seem to be the way to go.
In the event of depletion of resources and pollution of the environment, the
need to go green is the need of the hour.
These trends are alarming people and making them shift to green buildings.
Introduction
Green buildings can be defined as the buildings that are environmentally
sustainable and responsible.
Green buildings make efficient use of resources throughout the whole
processes like design, building, usage and maintenance.
Green buildings are not only environmentally responsible but also serve all
the other purposes which regular buildings provide.

Green Building by the Numbers
The value of green building construction was approx $12 billion in 2008 and was increased to $60 billion by 2010.
The construction market accounts for 14.2% of the $10 trillion U.S. GDP
The construction market involves a workforce of 120 million people
The three largest segments for nonresidential green building construction (office, education and health care) will account for more than 80% of total nonresidential green construction in 2016.
Buildings
In the United States alone, buildings account for:
65% of electricity consumption
36% of energy use
39% of greenhouse gas emissions
30% of raw materials use
30% of waste output (136 million tons annually)
12% of potable water consumption
Buildings are one of the heaviest consumers of natural resources.
Factors that are expediting the growth of green buildings:
Unprecedented level of government initiatives
Heightened residential demand for green construction
Improvements in sustainable materials

Are Green Buildings Economical?
The construction cost of green buildings is initially on the higher side
than regular buildings but its long term economic benefits are
immense.
Economic benefits like lessening running expenses and enhancing
inhabitant productivity are provided by green buildings.
Green buildings must be looked on as an investment which reaps rich
dividends in the longer run.
Health and environmental Benefits
Health and community benefits:
Improve air, thermal, and acoustic environments
Enhance occupant comfort and health
Minimize strain on local infrastructure
Contribute to overall quality of life
Environmental benefits:
Enhance and protect ecosystems and biodiversity
Improve air and water quality
Reduce solid waste
Conserve natural resources
Maintenance and Costs
The maintenance of green buildings is simple and cost effective.
Green buildings enhance the building durability.
Green buildings ensure good health of the occupant.
Studies suggest that we can attain around 30% energy savings, 20-50% water
savings and 50% reduction in cleaning expenses.
Aspects of Green Building Construction
The criteria for accessing buildings materials is based on resource
management, indoor air quality, contamination and performance.
The energy consumed is huge in the case of building materials and hence
environmentally sustainable building materials must be used in construction.
In the construction of green buildings materials like bamboo for flooring,
woven wool for carpeting and non-volatile organic compounds for paints are
used which are environmentally sustainable.
Aspects of Green Building Construction
Materials with low longevity, regardless of how benevolently created, can
scarcely qualify as green.
Wood is a perfect example for a green material which is characterized by high
durability and is environmentally sustainable
Green building use renewable sources of energy which never deplete hence
benefiting the future generations.
Taking into consideration all the aspects mentioned above, green building
construction can be taken up having less or no harm on the environment.
Green Buildings Impact On Productivity
The ultimate goal of any organization is to maximize productivity and
increase work efficiency.
The working environment is not only critical for a employee’s comfort but
also for his health.
Green buildings ensure occupational health and comfort of the employee and
in turn enhance the productivity of an organization.
Green Buildings Advantages
Green buildings ensure good air and water quality.
Green buildings have an effective waste water management system.
Green buildings ensure sustainability of resources.
Economic benefits like lessening running expenses and enhancing inhabitant
productivity are provided by green buildings.
Green buildings also ensure quality of life.
GREEN BUILDING RATING SYSTEMS
The green building development addresses various regions, for example, energy efficiency, water administration, material production, building process, tenant wellbeing, indoor air quality, reusing, reusability and waste administration.
LEED green building program is the preferred rating system for use generally.
LEED or leadership in energy and environmental design certified buildings remain to be healthier places to live, highly energy efficient and high performing.
Green Building Goals
The main goal of green buildings is help the environment to improve its
sustainability.
Adoption of green buildings not only benefits an individual but also sustains
the environment simultaneously.
Conclusion
Green building methodology is key in the event that we are to accomplish the
short-and long haul objectives of sustainability, including monitoring energy,
water and enhancing indoor air quality, in the assembled environment.
It is generally not as tuff as people make it out to be and you will tend to feel
better about yourself when you adopt the green movement.
