Green buildings are designed to reduce environmental impact and improve occupant health through efficient resource use, waste reduction, and enhanced indoor air quality. They are characterized by energy and water conservation, sustainable material selection, and measures to protect environmental and occupant health. Popular standards for green building certification include LEED, Green Globes, and Energy Star. Key aspects of green building include efficient design, construction practices like waste reduction, and selecting sustainable materials. Benefits include environmental, social and economic gains, though higher costs and lack of experience pose obstacles.
Green buildings
- 2. What is a “Green Building” “Green” Buildings are high performance structures that also meet certain standards for reducing natural resource consumption
- 3. What is a “Green Building”? • “Green” or “Sustainable” buildings are characterized by: – efficient management of energy and water resources – management of material resources and waste – restoration and protection of environmental quality – enhancement and protection of health and indoor environmental quality
- 4. What is a “Green Building”? • Green Building standards include: – Leadership in Energy and Environmental Design (LEED) – Green Globes – BuiltGreen – Energy Star – India Bureau of energy efficiency
- 5. 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
- 6. Construction • The act of “building” a building • 10-30% of Municipal Waste Goals: • 3 R- Reuse, Reduce, Recycle • Higher quality • Trained crew • Design based on standard size • Renovate existing buildings
- 7. Construction - Implementation 3 Rules of Green Building Construction: • Greenest building is that which isn’t made • Every building should be as small as possible • Don’t contribute to urban sprawl Implementation: • Solar Panels, Solar equipment for energy • Green Roofs, Rain Gardens, Green Space • Packed Gravel • Efficient plumbing, Insulation, windows • Low VOC Paints Taipei 101- Tallest Green Building
- 8. Building Design Goal: 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
- 9. Building Design • Central dehumidification system and dual flush toilets • Building with trees shaded on west and east • Central vacuum system • Rain water collection • Light colored exterior walls • Lighting control using motion detection sensors
- 10. Principles Of Green Materials • Choose products: – made from environmentally attractive materials – that are green because of what isn’t there – that reduce environmental impacts during construction, renovation or demolition – that reduce environmental impacts of building operation – that contribute to a safe, healthy indoor environment
- 11. Focus Building Materials Roofing (Reflective and light) Asphalt / fiberglass composition Aluminum / steel Metal Floor Coverings (recycled with no off-gassing) Wood Natural linoleum Carpeting / carpet pads
- 12. • Doors – Wood – Fiberglass – Steel with varying types of cores, from solid core oak, maple, to old mahogany and hollow core interiors • Windows – vinyl framed windows to wood framed, – single pane – double pane – UV film – argon gas filled.
- 13. Benefits of Green buildings Buildings have an enormous impact on the environment, human health, and the economy. The successful adoption of green building strategies can maximize both the economic and environmental performance of buildings. Environmental benefits Social benefits Economic benefits
- 14. 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 • One of the major issues that is faced in the construction of any green building is the: Design and construction issues
- 15. Design & Construction Issues Improper installation due to inexperience of contractors Failure of innovative materials to meet performance requirements Unanticipated performance failures due to design or construction flaws. Construction Delays Failure to maintain adequate records
- 16. The various steps involved in construction of any green building are very often the root cause of delay in their completion. – Timing – Construction process – Substitutions – Commissioning
- 17. Green buildings in India
- 18. Support For Green Buildings • 1) LEED LEED has inspired hundreds of laws, incentive programs LEED is intended to help building owners be environmentally responsible. LEED also has grown to more than 200 volunteers in nearly 20 committees with 150 professional staff. LEED standards is being applied to more than 7,000 projects in the United States and over 30 countries
- 19. Conclusions • Green Building Certifications present a moving target • Critical to work with clients early and continuously to determine goals and objectives • Focus on objective performance measures and clear allocation of risks and responsibilities • Green building issues are presented in nearly every phase of development – look for opportunities to improve old practices and “boiler plate” • Don’t get bogged down, but don’t be afraid to innovate
