Green buildings

|
A green building depletes as little of the natural resources during
its construction and operation. The aim of a green building design is
to
- Minimize the demand on non-renewable resources and maximize the
utilization efficiency of these resources when in use, and
- Maximize reuse and recycling of available resources
- Utilization of renewable resources.
It maximizes the use of efficient building materials and
construction practices; optimizes the use of on-site sources and sinks
by bio-climatic architectural practices; uses minimum energy to power
itself; uses efficient equipment to meet its lighting,
air-conditioning, and other needs; maximizes the use of renewable
sources of energy; uses efficient waste and water management practices;
and provides comfortable and hygienic indoor working conditions.
The following aspects of the building design are looked into in an
integrated way in a green building:
- Site planning
- Building envelope design
- Building system design HVAC (heating ventilation and air
conditioning), lighting, electrical, and water heating
- Integration of renewable energy sources to generate energy
onsite.
- Water and waste management
- Selection of ecologically sustainable materials (with high recycled
content, rapidly renewable resources with low emission
potential, etc.).
- Indoor environmental quality (maintains indoor thermal and visual
comfort and air quality)

GRIHA, an acronym for Green Rating for Integrated Habitat
Assessment, is the National Rating System of India. It has been
conceived by TERI and developed jointly with the Ministry of New and
Renewable Energy, Government of India. It is a green building 'design
evaluation system', and is suitable for all kinds of buildings in
different climatic zones of the country.

- CESE (Centre for Environmental Sciences and Engineering) Building,
IIT Kanpur, Uttar Pradesh
- Suzlon One Earth, Suzlon Energy Limited, One
Earth, Hadapsar, Pune 411 028
