Greenbuilding with examples
- 2. What is a green building? A green building is a sustainable or a high performance building which: uses less water optimizes energy efficiency conserves natural resources generates less waste provides healthier space for occupants as compared to conventional buildings Green building is the practice of creating structures and processes that are environment friendly and resource efficient throughout the lifespan of a building right from site selection to design, construction, operation, maintenance, renovation and deconstruction.
- 3. Why green buildings ? One of the main goals is to make Earth more sustainable Global climate change has become an increasingly serious concern for the future At the rate we are developing, the earth is simply not sustainable. In coming years, we will begin to run out of certain natural resources that are needed in order for us to survive. The ideal green building would be a building project that would allow us to preserve most of the natural environment around the project site, while still being able to produce a building that is going to serve a purpose.
- 4. Benefits Environmental Benefits: Reduce wastage of water Conserve natural resources Improve air and water quality Protect biodiversity and ecosystems Economic Benefits: Reduce operating costs Improve occupant productivity Create market for green product and services Social Benefits: Improve quality of life Minimize strain on local infrastructure Improve occupant health and comfort
- 5. Issues for investment in green buildings: There is a misconception that going green costs more money and hence people avoid it. It may be a bit costly to get started because green materials and products can be more costly, but the savings are more in the long term. Green building is more of an investment that will be able to save us money, as well as an investment that will be able to help the environment - a win-win situation for everyone!
- 6. Changing features of green buildings It is to be noted that not all green buildings need to be the same. Different countries and regions have a variety of characteristics all of which shape their approach to green building, such as: distinctive climatic conditions unique cultures and traditions, diverse building types and ages wide-ranging environmental, economic and social priorities
- 8. Fundamental principles for going ‘green’: Structure efficiency Structure has a great impact on cost and performance Energy efficiency Using natural light and trees for shading rather than air-conditioning Water efficiency Minimising water consumption by proper collection and use, then purify and reuse Material efficiency Recyclable materials is better to use Waste and toxic reduction Waste from one thing can be an input for some other thing, if used wisely.
- 9. LEED - Leadership in Energy and Environmental Design, LEED is the most widely used green building rating system in the world. LEED provides a framework to create healthy, highly efficient and cost- saving green buildings. LEED certification is a globally recognized symbol of sustainability achievement.
- 10. Green Building Rating System India There are two primary Rating systems in India. GRIHA - Green Rating for Integrated Habitat Assessment IGBC - Indian Green Building Council GRIHA aims at ensuring that all kinds of buildings become green buildings. GRIHA even rates non-air conditioned buildings as green and puts great emphasis on local and traditional construction knowledge. Green projects rated by IGBC fall under one of the following levels (in ascending order): Certified, Silver, Gold and Platinum. The more the energy efficient building, the higher the certification level

- 32. Some green construction practices: Using sustainable building materials like recycled glass and steel, as well as renewable materials like bamboo and rubber. Installing energy-efficient windows and doors. Using lower-VOC (volatile organic compounds) paints. Constructing green roof systems which provide onsite gardens, rainwater management and protection from the effects of harmful UV light. Adding water harvesting and purification systems that both manage and make the most use of rainfall. Maximizing natural light, saves on lighting requirements also helps keeping buildings warm in colder months. Using renewable energy to power the building like solar panels and windmills.
- 33. Green building benefits Healthier and happier workers—employees that work in green buildings report fewer headaches, as well as improvements in asthma and allergy symptoms. Greater likelihood a green building will sell for more money than a standard building. Additional business opportunities that come from appealing to an ever-growing pool of conscious consumers. Reduced energy costs and operating costs Reduced Government tax incentives Reduced maintenance costs
- 34. What if we ignore green building concepts? Because of indiscriminate use of concrete and conventional building materials in urban areas, the normal atmospheric temperature is relatively higher than areas with few buildings. CO2 emissions from such buildings add to the environmental pollution and global warming which might result in catastrophic consequences such as: Reduction in agricultural output and global food production Rise in the sea level in coastal plains Alteration in ecosystem and biodiversity pattern Prolonged flooding in regions receiving abundant rainfall.
