GREEN BUILDING
Introduction
structure and process that is environmentally responsible and resource-efficient throughout a building's life-cycle
Efficiently using energy, water, and other resources
Protecting occupant health and improving employee productivity
Reducing waste, pollution and environmental degradation
Current Scenario of Green Building Technology
Application of green building concept is relative new and is being recently getting adopted in the society.
Growing awareness of sustainability within India, competency and encouraging returns will encourage the real developers to shift towards construction of green buildings.
GREEN BUILDING CRITERIONS
Sustainable siting and design
Green building materials
Water efficiency
Energy efficiency
On-site power generation
Indoor air quality
GREEN BUILDING BENEFITS
30% to 40% reduction in operating cost.
Health and safety of building occupants.
Incorporate latest techniques and technologies.
Improve occupant health
Reduce pollution
Reduce water usage (by 20%- 30%)
Eliminates creation of waste
Reduce power consumption (by 40%- 50%)
Green architecture may have these characteristics:
Energy-efficient lighting and appliances.
Water-saving plumbing fixtures.
Landscapes planned to maximize passive solar energy.
Minimal harm to the natural habitat.
Alternate power sources such as solar power or wind power.
SALIENT FEATURES

Health and safety benefits
CASE STUDY
OLYMPIA TECH PARK CHENNAI, INDIA
Building Type: Office
Approximate gross area: .13,00,000 Sq. Ft
Number of floors above ground: 8
Year of completion: 2006
Main Green Features of the project
The client (Olympia) and the architects developed a strategic green option to recycle/reuse the entire building.
Allows opportunities for natural ventilation in summer and acts as a warm buffer zone in winter.
Energy efficient HVAC and electrical equipment and systems design providing considerable energy savings of over 25%.
High efficiency water system design resulting in water use reduction by over 40%.
CONT…..
Effective use of recycled materials for over 15% of the project cost.
Utilization of regionally manufactured materials for over 60% of the project cost thereby reducing the impact of environmental pollution.
Exemplary performance on construction waste management diverting close to 98% of the construction waste generated at site.
CONCLUSION:
It becomes inevitable to steadily switch over to the use of energy efficient building materials and technologies and device methods and mechanisms to utilize industrial/mine wastes and recycling and reuse of building wastes for the manufacture of building materials and products for the sustainable construction practices.
