Introduction to Green Building.
What is Green?
Voluntary pursuit of any activity
that encompasses the concern for energy efficiency, environmental management,
water management, renewable energy, waste management and recycling.
A Green building is the one which is environmentally responsible,
profitable and healthy place to live and work.
Benefits of Green Buildings:
•
30 – 40% reduction in operation cost.
•
Energy Savings up to 40-50 %
•
Water Savings up to 20-30 %
•
Reduce Operating cost from day one.
•
Green corporate image.
•
Health and safety of building occupant.
•
Enhance occupant comfort.
•
Improve productivity of occupants.
•
Imbibe best operational practice from day one.
•
Incorporate best and latest techniques and technologies present
in the industry.
•
Offers both tangible and non tangible benefits for long term.
The Green Building and Conventional Building both look alike
externally and the use of both the building is the same. The only difference is
Operational savings and Concern for Human comfort And Indoor environment
BENEFITS
A building that follows the parameters laid down offers
benefits, both tangible and intangible.
A 20 to 30 per cent saving in water and 30 to 50 per cent in
operating energy costs are the tangible benefits. The intangible benefits include
enhanced air quality, excellent day lighting, health and well being of the
occupants, safety benefits and conservation of scarce resources. Water
conservation through reduced use and recycling and lower energy consumption
through the use of efficient electrical devices are emphasized.
Soil erosion control with regard to site efficiency and adoption
of rainwater harvesting systems and installation of water efficient fixtures in
the case of water efficiency.
SALIENT FEATURES OF GREEN BUILDING
- The Built Environment has profound Impact on our Natural Environment, Economy, Health and Productivity.
- Green Building can Design, Build and Operate a Building that Delivers High Performance Inside and outside.
- Building annually consumes more than 20% of electricity used in India.
- Green Building practices can substantially reduce or eliminate negative environmental impacts and can improve existing unsustainable design, construction and operational practices.
- Green Building reduces Operational costs, enhances Building marketability, Increase worker productivity, Improves Indoor Environment Quality, and Reduces potential liability resulting from Indoor Air Quality problems.
- People Friendly GREEN Building design gains productivity by 16%, Reduction in Absenteeism and improved work quality, which benefits building stakeholders, including owner, occupants and general public.
- In development circles, Green has gone from a boutique idea to a mandatory part of the Architecture and Construction.
- Almost all Construction waste is recycled or reused.
- Green Buildings consumes about 25% less energy than conventional buildings.
- In Green Buildings Interiors are done with low V.O.C. content materials, adhesives, sealants, paints and carpets, which reduces allergies and illness.
GREEN BUILDINGS
(i)
Controls erosion to reduce negative impacts on water and air
quality.
(ii)
Avoid development of inappropriate sites and reduce the
environmental impact.
(iii)
Channel development to urban areas with existing Infrastructure,
protect green fields and preserve habitat and natural resources.
(iv)
Rehabilitates damaged sites where development is complicated by
real or perceived environmental contamination, reducing pressure on undeveloped
land.
(v)
Reduce pollution and land development impacts from automobile
use.
(vi)
Conserve existing natural areas and restore damaged areas to
provide habitat and promote biodiversity.
(vii)
Limit disruption of natural water hydrology by reducing
impervious cover, increasing onsite infiltration and managing storm water
runoff.
(viii)
Limit disruption of natural water flows by eliminating storm
water runoff, increasing onsite infiltration and eliminating contaminants.
(ix)
Reduces Heat Islands to minimize impact on microclimate and
human habitat.
(x)
Minimize light trespass
from the building and site, reduce sky-glow to increase night sky access,
improve nightmare visibility through glare reduction.
(xi)
Limit or eliminate use of potable water for landscape,
irrigation air conditioning make up.
(xii)
Reduce the generation of waste water and potable water demand,
while increasing local aquifer recharge.
(xiii)
Reduce Ozone depletion.
(xiv)
Increase demand for building products that incorporated recycled
content materials, therefore reducing impacts resulting from extraction and
processing of new virgin materials.
(xv)
Reduce the use and depletion of finite raw and long cycle
renewable materials by replacing them with rapidly renewable materials.
(xvi)
Provide a comfortable thermal environment that supports the
productivity and well-being of building occupants.
