Green building seminar presentation by Pirpasha Ujede

  1. 1. GREEN BUILDING Seminar by Guided byProf M. B. Varma Pirpasha UjedeApplied Mechanics Department T.E.-CivilGovernment College of Engineering, BE09F01F012 (18)Aurangabad
  3. 3. Is this GreenBuilding
  4. 4. Green BuildingDesign and construction practices that significantly• Reduce, or eliminate the negative impact of buildings on the environment and its occupants with regard to site planning;• Safeguarding water use and water use efficiency;• Promoting energy efficiency and renewable energy; conserving materials and resources; and promoting indoor environmental quality.”• Extending the life span of natural resources• Providing human comfort• Safety and productivity (US Green Building Council)
  5. 5.  Minimum use of conventional energy Utilization of green energy Reduction in water requirement and waste
  7. 7. Insulated Concrete Forms:These preformed blocks are made with expanded polystyrene (EPS) and metal rebar which are be stacked to build the frame. They are then filled with concrete to create an insulated and exceptionally strong wall. The Benefits of Building a Home with Insulated Concrete Forms• Energy Efficiency• Noise Reduction• Fire-resistance• Strength• Prevention of mildrew rot
  8. 8. GREEN CEMENT• It is produced by using mainly two materials fly ash and cement kiln dust (CKD). These two materials are industrial wastes. Both of these do not produce CO2 or other green house gases and thus is ecofriendly.• If the two materials are appropriately blended, the alkalis from cement kiln dust may Activate hydration of fly ash, and the blends may create a cementitious material in which the waste material deficiencies will be converted into benefits.
  9. 9. CAVITY WALLS• Cavity walls consist of two skins separated by a hollow space (cavity). The skins are commonly masonry such as brick or concrete block.• They provide better sound and heat insulation and most importantly resistance to rain penetration.• The major products used for insulation between the two walls are: – Rigid foam board – Rigid fiber board – Spray Polyurethane foam
  10. 10. GREEN FIBRES• Substitute glasses by green fibers or ecofriendly glasses, recycled glasses for window panes and all other places of glass usage.• Use recycled glasses to have reduce harm to the environment caused by glass industries.
  11. 11. GREEN WOOD• Green wood is made by pressing together hemp fibers, which are available readily and in plenty with bio-degradable plastics at a high temperature.• When the building is demolished or renovated for any purpose, this green wood can be directly sent to landfills and thus is harmless to the environment.
  12. 12. Green Paint• Traditional household paints contain many chemicals, including volatile organic compounds (VOCs), including benzene, formaldehyde, and toluene, which are a large group of carbon-based chemicals that are volatile, meaning that they like to exist as a gas.• Some of these VOCs have been linked to bad health outcomes, including eye, nose and throat irritation, nausea, headaches, and even cancer.
  13. 13. Feasible Green Technologies• Solar Photovoltaic• Wind Energy• Solar Thermal, Improved Water Mill, Geothermal Energy
  14. 14. Solar Photovoltaic• Converts sunlight into electricity using semi conductor modules.• Used generally for meeting lighting requirements, they can also be used for pumping water, refrigeration, communication, and charging batteries.• Solar photovoltaic has application as green agricultural energy source for pumping water street lighting in villages, lighting in rural houses and pest management• The high –powered devices produce no waste or pollution.
  15. 15. Wind Energy• Wind energy is in a boom cycle. Overall, wind energy contributes only 1% of global electricity generation. Its importance is increasing in the sense that comparatively with other sources; the wind energy produces less air pollutants or greenhouse gases.
  16. 16. LEED• GRIHA
  17. 17. Points scored Rating 50–60 61-70 71-80 81-90 91-100
  18. 18. 1. Registration2. Submission of documentation3. Preliminary evaluation by ADaRSH Technical team4. Evaluation by panel of experts5. Preliminary rating with comments sent to project team6. Final submission of documents7. Final evaluation by panel of experts8. Approval of rating by advisory committee9. Award of rating
  19. 19. LEED Rated Buildings Platinum Suzlon Energy Ltd., Pune Biodiversity Conservation India Ltd. (BCIL), Bangalore ITC Green Centre, Gurgaon Gold Olympia Technology Park, Chennai Nokia, Gurgaon Silver Rajiv Gandhi International Airport, Hyderabad
  20. 20. Conclusions• Non-toxic construction.• Use of durable, effective, resource efficient materials.• Reliance on the sun for day lighting.• Recycling wastes into nutrients
  22. 22. BENEFITS• Energy savings : 20 - 30 %• Water savings : 30 - 50%• Enhanced air quality,• Excellent day lighting,• Health & wellbeing of the occupants,• Conservation of scarce national resources• Enhance marketability for the project.
