Green Building in India with Case Study

The presentation comes with definitions, uses, advantages, etc.
Including the case study of Green Building in India &
References in the end are also provided.

1. Outline What is Green Building? Why is Green Building Important? Three aspects of new project planning Obstacles Benefits of Green Building Advantages of Green Building Disadvantages of Green Building Case Study References

2. What is Green Building? “Green or sustainable building is the practice of creating healthier and more resource-efficient models of construction, renovation, operation, maintenance, and demolition .”

3. Why is Green Building Important? 4000 kgs 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 drinking water consumption. Indoor levels of pollution are commonly 2 to 5 times higher than outdoor pollution levels

4. 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

5. Construction Construction waste accounts for 10 to as much as 30% of municipal waste stream R’s of Eco-friendly Fashion Reduce / Reuse / Recycle/ Repurpose/ Reinvent Building design based on standard sizes of materials Buy higher quality to reduce rejects Recycle (use scraps) Train crew Renovate an existing building

6. Building Design 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

7. Materials Choose materials that have low environmental costs and do not contribute to indoor air pollution Engineered Wood (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

8. Obstacles 93% of consumers worry about their home’s environmental performance. However, only 18% are willing to pay more to reduce the impact. There are higher initial costs for Green Building Customers are concerned they would be sacrificing comfort

9. Benefits of Green Building Environmental Benefits: Reduce wastage of water Conserve natural resources Improve air and water quality Protect biodiversity and ecosystems

10. Economic Benefits Reduce operating costs Improve occupant productivity Create market for green product and services Enhances asset value & profits Optimizes life-cycle economic performance

11. Social Benefits Improve quality of life Minimize strain on local infrastructure Improve occupant health and comfort

12. Advantages of Green Building Cost Efficiency Preserving infrastructure High ROI (Return on Investment) rates

13. Disadvantages of Green Building Location Availability No air cooling features

14. Case Study INDIRA PARYAVARAN BHAWAN Location: 166, Jor Bagh , New Delhi Coordinate: 28.58527034,77.21819948

15. Project of ministry of environment and forests for construction of new office building at new Delhi. The basic design concept of the project is to make the net zero energy green building. PLOT AREA :9565sq m HEIGHT :35m Built-up area : 31,400 m2 (18726 m2 – superstructure & 12675 m2- Basement ) Construction Started : January 25, 2011 Construction Completed : October 31, 2013 India’s first Net Zero Building , This means that this is a building with zero net energy consumption where the total amount of energy used in the premises on an annual basis is more or less equal to the amount of renewable energy created on the site.

16. Achievements 40% savings in energy, zero electricity billing, 55% savings in water largest roof top solar power system in any multi storeyed building (930kw) The building is rated as a 5-star GRIHA (Green Rating for Integrated Habitat Assistant) by MNRE (Ministry of new & Renewable) & LEED (Leadership in Energy & Environmental Design) India Platinum by Indian Green Building Council (IGBC) rating.

17. ARCHITECTURAL DESIGN STRATEGIES Building form wrapped around a pedestrian-friendly shaded green open courtyard. A continuous green axis from front of site across the atrium. Eco park within the courtyard shall contain a self sustaining low. Large openings in building form on South and North sides. Surrounding open area parking free by providing adequate parking in the basement. Effective ventilation by orientating the building.

18. BUILDING PLANNING AND CONSTRUCTION MEASURES Reduce landscape water requirement: Drip irrigation Use of native species of shrubs and trees having low water demand in landscaping •Low lawn area so as to reduce water demand. Reuse of treated water for irrigation Reduce water use in the building55% reduction in overall use of water. This was achieved by using: Low discharge fixtures Dual Flushing cistern Waste water treatment Reuse of treated water for irrigation and cooling towers for HVAC Rain water harvesting Efficient water use during construction. Use of curing compound

19. Energy Conservation Measures

20. MATERIALS Stone available in nearby area for flooring Terrazzo flooring with locally available stone materials. Jute bamboo composite for door frames & shutters. UPVC windows with hermetically sealed double using low heat transmittance index glass. Use of high reflectance terrace tiles for low heat ingress Avoided aluminum as it has high embedded energy Sandstone Jalis . Stone and Ferrocement Jalis FALG (Fly Ash Lime Gypsum) bricks and AAC blocks are used in the construction instead of clay bricks. High Efficiency Glass
