Green Presentation

  1. 1. A building should create delight when you enter, serenity & health when occupied and regret when departed. A Green Building is a major attempt in this direction! Indian Green Building Council GREEN BUILDINGS – SOME KEY FACTS
  3. 3. U.S.G.B.C L.E.E.D. Non-profit organization committed to expanding sustainable building practices. working to advance structures that are environmentally responsible, profitable, and healthy places to live and work. Members includes building owners and end-users, real estate developers, facility managers, architects, designers, engineers, general contractors, subcontractors, product and building system manufacturers, government agencies, and nonprofits. LEED is the nationally accepted benchmark for the design, construction and operation of high performance green buildings. LEED gives building owners and operators the assessment tools to measure their buildings’ performance. Architects, real estate professionals, facility managers, engineers, interior designers, landscape architects, construction managers, lenders and government officials all use LEED.
  4. 4. <ul><li>How are credit points awarded under LEED-INDIA? </li></ul><ul><li>Credits are awarded based on five categories of performance: </li></ul><ul><li>1. Sustainable Sites </li></ul><ul><li>2. Energy and Atmosphere </li></ul><ul><li>3.Water Efficiency </li></ul><ul><li>4.Indoor Environmental Quality </li></ul><ul><li>5.Materials and Resources </li></ul><ul><li>Projects can earn additional points </li></ul><ul><li>Innovation in Design category, </li></ul><ul><li>demonstrating exceptional performance above LEED-INDIA requirements. </li></ul><ul><li> NEXT </li></ul>
  5. 5. <ul><li>1. Sustainable sites </li></ul><ul><li>Start by selecting a site that is well suited to taking advantage of mass transit. </li></ul><ul><li>Protect and retain existing landscaping and natural features . Select plants that have low water and pesticide needs, and generate minimum plant trimmings. Use compost and mulches. This will save water and time. </li></ul><ul><li>Recycled-content paving materials, furnishings, and mulches help close the recycling loop. </li></ul><ul><li>BACK </li></ul>
  6. 6. <ul><li>2. Energy and Atmosphere </li></ul><ul><li>Building shape and orientation , passive solar design, and the use of natural lighting. </li></ul><ul><li>Develop strategies to provide natural lighting .  </li></ul><ul><li>Install high-efficiency lighting systems with advanced lighting controls. Include motion sensors tied to dimmable lighting controls. Task lighting reduces general overhead light levels. </li></ul><ul><li>Use a properly sized and energy-efficient heating/cooling system in conjunction with a thermally efficient building shell. Maximize light colors for roofing and wall finish materials, install high R-value wall and ceiling insulation, and use minimal glass on east and west exposures. </li></ul><ul><li>Minimize the electric loads from lighting, equipment, and appliances. </li></ul><ul><li>Consider alternative energy sources, such as photovoltaics and fuel cells, that are now available in new products and applications. Renewable energy sources provide a great symbol of emerging technologies for the future. </li></ul><ul><li>Computer modeling is an extremely useful tool in optimizing design of electrical and mechanical systems and the building shell. </li></ul><ul><li>BACK </li></ul>
  7. 7. <ul><li>3. Water Efficiency </li></ul><ul><li>Design for dual plumbing to use recycled water for toilet flushing or a gray water system that recovers rainwater </li></ul><ul><li>Minimize wastewater by using ultra low-flush toilets, low-flow shower heads, and other water-conserving fixtures. </li></ul><ul><li>Use re-circulating systems for centralized hot water distribution . </li></ul><ul><li>Install point-of-use water heating systems for more distant locations </li></ul><ul><li>BACK </li></ul>
  8. 8. <ul><li>4. Indoor Environmental Quality </li></ul><ul><li>Eliminate poisons and toxic off gases </li></ul><ul><li>Use more of natural light </li></ul><ul><li>Less noise by using sound absorption materials and methods </li></ul><ul><li>Views to the outside </li></ul><ul><li>Air quality and thermal comfort </li></ul><ul><li>The quality of these who work in green buildings are more productive and take fewer sick days </li></ul><ul><li>Sick Building Syndrome has been attributed to poor air quality caused by air-tight construction and the off-gassing of volatile organic compounds (VOCs) from such things as finishes, adhesives, furniture systems, wall coverings, office machinery, and in some instances, molds. </li></ul><ul><li>The release of harmful VOCs (such as carcinogenic urea formaldehyde) is one of the biggest concerns when choosing products and materials for interior spaces . As such, indoor air quality (IAQ) is on most radar screens these days, and anyone specifying green products for certification or just seeking to create a healthy interior space will find myriad resources. </li></ul><ul><li>BACK </li></ul>
  9. 9. <ul><li>5. Materials and Resources </li></ul><ul><li>Select sustainable construction materials and products by evaluating several characteristics such as reused and recycled content, zero or low off-gassing of harmful air emissions, zero or low toxicity , high recyclability , durability, longevity, and local production. Such products promote resource conservation and efficiency. For example, GREENGUARD is an independent, non-profit organization that certifies interior products and finishes. </li></ul><ul><li>Use dimensional planning and other material efficiency strategies. These strategies reduce the amount of building materials needed and cut construction costs. For example, design rooms on 4-foot multiples to conform to standard-sized wallboard and plywood sheets. </li></ul><ul><li>Reuse and recycle construction and demolition materials . For example, using inert demolition materials as a base course for a parking lot keeps materials out of landfills and costs less. </li></ul><ul><li>Incorporate a solid waste management program that prevents waste generation. </li></ul><ul><li>BACK </li></ul><ul><li>NEXT </li></ul>
  10. 10. <ul><li>What are the benefits of LEED-INDIA certification? </li></ul><ul><li>  </li></ul><ul><li>LEED-INDIA certification is third-party validation of a building's performance. </li></ul><ul><li>LEED-INDIA certified projects blend environmental, economic and occupant - oriented performance. </li></ul><ul><li>They cost less to operate and maintain, are energy- and water-efficient , </li></ul><ul><li>Have higher lease-up rates than conventional buildings in their markets </li></ul><ul><li>Physical demonstration of the values of the organizations that own and occupy them </li></ul>
  11. 11. <ul><li>BENEFITS OF GREEN BUILDINGS </li></ul><ul><li>Environmental benefits : </li></ul><ul><li>Reduces impacts of natural resources and consumption </li></ul><ul><li>Economic benefits : </li></ul><ul><li>Reduces operating costs, is cost effective in the long run </li></ul><ul><li>Health and safety benefits </li></ul><ul><li>Enhances occupant comfort and health </li></ul><ul><li>Community benefits </li></ul><ul><li>Minimizes strain on local infrastructures and improves quality of life </li></ul>
