Green Building-
Green building is the practice of creating structure and using processes that are environmentally responsible and resource efficient throughout the building life cycle from sitting to design construction, operation, maintenance, renovation and demolition.
A green building is one which uses less water, optimise energy efficiency, conserve natural resources, generate less waste and provides healthier space for occupants when compared with conventional building.


Green buildings are designed to meet certain objectives such as a protecting occupant health, improving employee productivity ,using energy, water and other resources more efficiently and reducing the overall negative impacts on environment.


Objectives of Green Building-
Green Buildings are designed to reduce the overall impact on human health and the natural environment by the following ways:
Using energy, water and other resources efficiently.
By reducing waste, pollution, and environmental degradation.
Implementing the three R's system – Reduce, Reuse and Recycle
Benefits Of Green Building-
Green buildings are designed for achieving the sustainability
The essential aim of sustainable design is to create a place , product and services in a way that reduce use of non renewable resources, minimize impact on environment. And use locally available material to greater possible extent.
1. Economical benefits of green building-
Sustainable buildings reduce consumption of material and energy which offers major finance advantages that are-
Reduce operating cost and improve occupant performance due to efficient use of all utilities in building.
Creating, expanding and shaping markets for green product and services.

5. Objectives of Green Building- Green Buildings are designed to reduce the overall impact on human health and the natural environment by the following ways: Using energy, water and other resources efficiently. By reducing waste, pollution, and environmental degradation . Implementing the three R's system – Reduce, Reuse and Recycle

6. Benefits Of Green Building- Green buildings are designed for achieving the sustainability The essential aim of sustainable design is to create a place , product and services in a way that reduce use of non renewable resources, minimize impact on environment. And use locally available material to greater possible extent.

7. 1. Economical benefits of green building- Sustainable buildings reduce consumption of material and energy which offers major finance advantages that are- Reduce operating cost and improve occupant performance due to efficient use of all utilities in building. Creating, expanding and shaping markets for green product and services. Increased property value. Less maintenance. Optimization of life cycle economic performance. Decreased infrastructure strain .

8. 2. Environmental Benefits- Reduce impact of building construction and operation on – Soil, aquatic and forest eco system. Air and water quality Energy consumption. The energy saving could range from 20% to 30% and water saving around 30% to 50%. Improve landscape of building site. Reduce waste generation and dependency on artificial ventilation. Controls emission of green house gases.

9. Enhance and protect the biodiversity and ecosystem. Improve air and water quality. Conserve and restore natural resources. Offer energy efficiency, improved lighting, improved comfort and healthier environment.

10. 3.Social benefits- (1)Enhanced occupant comfort and health (2) Heightened aesthetic qualities (3) Minimizing strain on local infrastructure (4)Improved overall quality of life and standard of living. (5)Improved occupational productivity.

11. Disadvantages of green building- (1) Structural orientation : In order to optimise sun exposure, green building demand ideal structural positioning causing friction among neighbours. (2) Green roofs: In general, green roofs are comprised of multiple layers as a vegetation layer growing medium, drainage or water storage insulation, a water proofing membrane and roof support heavier than conventional roof. (3) Air cooling features : In a green building inmates may not have precise mechanism to regulate temperature through natural ventilation.

12. ( 4) Green buildings are expensive: There are additional costs during the construction phase of green building. But the operational and maintenance costs of a green-built home are significantly less. A building designed with passive solar and high-efficiency windows require less energy to heat and cool, less workload on units also results in lower repair cost and a more years of service. Green buildings use up less materials and are built better so they have higher value and will not need periodical replacement of costly materials. (5) Green homes are less appealing : The components used in green construction are engineered to last longer and require less maintenance. Building green also involves leaving more trees on the lots and less modification to terrain.

13. Design Aspects For Green Building- Green architecture is a green building design concentrates on four interrelated aspects- 1. Daylight : Maximising the natural light available throughout the day to occupants. 2. Natural ventilation : Maximising the use of natural systems instead of depending on artificial ventilation system. (3) Comfort : Providing a combination of acceptable temperature and air flow in order to provide a healthy and productive workplace which maximizes the potential productivity of its occupants .

14. 4.Materials and devices : All materials and devices used in green buildings need less consumption of energy and water causing low ecological impact, of renewable materials and low maintenance, replacement costs over the life the building

15. Design criteria of green building as per U.S. Green Building Council (USGBC) 1.Site sustainability- Site selection- the site of green building shall take place on one of the following ; In an exiting building envelope On brown field site On grey field site The green building should not be constructed at – Flood affected land Within 35 m of any wetland Within 150 m of fish pond and wildlife habitat conservation area.

16. Site development- A minimum 40% of the entire site area shall incorporate one or more combination of following: Shall have a vegetated roof with a minimum depth of growing medium of 75 m. Shall have porous pavers. Shall have permeable pavement with a minimum percolation rate of 100 lit/min-m2. 2.water use efficiency - Water consumption of commercial buildings can be reduced upto 50% using variety of innovation strategies of plumbing and mechanical system as well as the landscaping design.

17. Water use can be reduced by following ways- Site water use reduction Building water use reduction Domestic appliances Gray water use Rain water harvesting 3.Energy efficiency- All elements of the building , foundation framing, roof structure, floors and windows should be high energy efficient. Some measures to improve the energy efficiency of the building are- Orientation Building envelope Equipment and system lighting

18. Equipment And System – the following points must be consider while selecting the equipments- Select the chillers with high coefficient of performance select high efficiency cooling tower Use high efficiency motors, transformers and pumps. Lighting- Lighting consumes about 20% electricity in the building. Following points should be should be considered for less power consumption- Design n such way that building should get maximum day light. Select energy efficient luminaries like CFL, T-5, LED etc.

19. Overall lighting power density can be designed as less as 10 w/m2. Occupancy sensor control are used in conference rooms, class rooms, meeting halls to automatically turn off lighting (within 30 min.) when everybody lefts. 5.Indoor Air Quality- In order to maintain or enhance IAQ following points are considered. Paints- paints have major impact on aesthetical view and human health. All water based paints contain Voc which are harmful for health. Moisture resistant- products and systems that resist the moisture or inhibit the growth of biological contaminants in building should be used to protect the health of occupants.

20. Building entrance- all green building entrance shall employ mat system. Environmental tobacco smoke-smoking shall not be allowed inside the building. 5. Green building materials used in construction - Earthen Materials. Wood. Bamboo. SIPs (structural insulating panels). Insulated Concrete Forms. Cordwood. Straw Bale. Earth Bags. Cellular concrete
