This PPT cover the concept of Green Building. It includes how green building can be constructed.

1. ROLE OF TECHNOLOGY ON
ENVIRONMENT: GREEN BUILDING
PREPARED BY: JEGAN. S. NADAR

2. GREEN BUILDING
 A green building is one which uses less water, optimises energy
efficiency, conserves natural resources, generates less waste and provides
healthier spaces for occupants, as compared to a conventional building.
Jegan

3.  The residential building sector is one of
the largest consumers of electricity in
India.
 Continuous urbanisation and the growth
of population result in increasing power
consumption in buildings
 Thus, experts express the huge potential
for energy conservations through green
building
Jegan

4. Why is Green Building Important?
 8000lbs of waste are typically thrown into a landfill during the construction
of a 2000sqft home
 The buildings consume more than twice as much energy as all the cars
 Buildings account for 68% of total electricity consumption
 Buildings use 80% of total water consumption
 Indoor levels of pollution are commonly 2 to 5 times higher than outdoor
pollution levels Jegan

6. New Project Planning
 Construction – Reduce the amount of waste generated at a construction site
 Design – Building design details will help to reduce construction materials,
and energy/water requirements when completed
 Material Selection – Careful selection of construction materials will leave
less of an environmental impact

7. Construction
 Construction waste accounts for 10 to as much as 30% of municipal waste
stream
 Goal: Reduce / Reuse / Recycle
 Building design based on standard sizes of materials
 Buy higher quality to reduce rejects
 Recycle (use scraps)
 Train crew
 Renovate an existing building Jegan

8. Building Design
Goal: To design the building so that it requires less energy/water and is
healthier for inhabitants when it is complete and in use
 Air ducts for an efficient and healthy air flow
 Insulation
 Windows designed for maximum daylight
 Passive Solar Control
 Solar Cells
 Heat Exchanger for climate control system
 Location Jegan

9. Materials
Goal: Choose materials that have low environmental costs and do not
contribute to indoor air pollution
 Engineered Lumber (recycled and reclaimed material)
 Doors and Windows (energy and placement)
 Floor Coverings (recycled with no off-gassing)
 Roof Materials (Reflective and light)
 Energy Efficient Appliances

10. LEED (Leadership in Energy and Environmental Design)
 Created by the U.S Green Building Council (USGBC) in 1998
 Nationally recognized standard for Green Building
 Green Building Rating System
 Adapted for other countries
 Canada
 Australia
 Hong Kong
 India

11.  There are many energy efficient buildings in India, situated in a variety of
climatic zones. One of these is RMZ Millenia Park, Chennai, India’s largest
LEED goldrated Core and Shell green building.

12.  Traditional buildings were energy efficient because architecture depended
on the places.
 Buildings in the hot and dry regions, had corridors directing the wind to cool
naturally.
 Some examples are
 Hawa Mahal - Articulated windows provides cool breeze in a desert area
 Golkonda - Ventilation is designed to let in fresh cool breeze, in spite of
summer
