What is a Green Building?

•A sustainable or green building produces net zero or smaller carbon footprint or reduces the other harmful emissions.

•It is a building which does not have adverse effects on the ecological balance.

•These structures don’t have a negative impact on the environment as they generate their own energy from solar energy, wind energy etc.

Need for Green Buildings.

GLOBAL ENERGY USE

• The Earth has limited amount of energy sources like coal, petroleum, natural gases etc. so their use must be minimized. If these non renewable sources of energy are used excessively then our earth’s resources will get exhausted.

• The construction of buildings all over the world use 40% of earth’s materials and produces upto 20-30% solid waste which needs to be dumped.

• The carbon emitted from buildings is about 21% of the total carbon emission of the world.

• Therefore, green buildings are needed to reduce the carbon footprint and for preserving the non renewable sources of energy.

Features of green buildings.

Another type of green structure -

Visit to a green building.

Last year I visited a green building in Bhopal (MP) itself for doing further research on green buildings. It is constructed by an Indo-German company, Omega-Renk. It is the only LEED certified, platinum rated building in MP.

Some features of that building -

•It produces its own energy derived from solar and wind power.

•The waste material is also treated before dumping or is reused.

•Use of LED lights, furniture made from recyclable materials, water harvesting, motion sensing technology,

Pic – solar panels installed in the building to produce its own electrical energy derived from solar energy.

• materials used for construction are also eco friendly like flyash bricks or flyash concrete.

Paint used on the outer walls and roof had reflecting properties.

It helped in increasing the underwater level.

Pic – the monitor fixed at the wall showed details about the functioning of solar panels.

Pic – this is the workshop of that building which had thermal insulated roof and glass walls so that natural light can be used inside.

Pic – the lead platinum certificate awarded to that building.

Pic – partition walls are also made from glass for maximum utilization of the natural light, LED lights also used with motion sensing technology.

Pic – digital board installed which gave info about the amount of electricity produced, irradiation etc

COST FACTS -

•Cost of construction of a green building may be 5-30% more according to the rating.

•Energy cost go down by 30 – 40% as in 30 – 35 years of life cycle. But in normal building the energy cost exceed construction cost.

•10% overall cost saving potential over 10 years.

CONVENTIONAL BUILDINGS.

GREENBUILDINGS

What is LEED?

•LEED, or Leadership in Energy & Environmental Design, is a green building certification program that recognizes best-in-class building strategies and practices.

•To receive LEED certification, building projects satisfy prerequisites and earn points to achieve different levels of certification. Prerequisites and

credits differ for each rating system, and teams choose the best fit for their project. •Established in 1993, in Washington DC.

RATING SYSTEM OF LEED -

Certification based on the points scored by the structure.
