  • 9. NEW ECO-FRIENDLY PRODUCT IN MARKETLight Weight Concrete:Autoclaved aerated concrete (A AC), also known as autoclaved cellular concrete (ACC) or autoclaved lightweight concrete (ALC) was invented in the mid- precast building material that simultaneously provides structure, insulation, and fire
  • 10. Advantages: AAC’s excellent thermal efficiency makes a majorcontribution to environmental protection by sharplyreducing the need for heating and cooling in buildings. AAC’s easy workability allows accurate cutting, whichminimizes the generation of solid waste during use. Unlikeother building materials, AAC can eliminate the need to beused in combination with insulation products, which increasethe environmental impact and cost of construction.
  • 11. AAC’s high resource efficiency gives it lowenvironmental impact in all phases of its life cycle,from processing of raw materials to the disposal ofAAC waste.AAC’s light weight also saves energy in transportation.The fact that AAC is up to five times lighter thanconcrete leads to significant reductions inCO2 emissions during transportation. In addition, manyAAC manufacturers apply the principle of producing asnear to their consumer markets as possible to reducethe need for transportation.

  • 19. Design Philosophy and Approachfor the Structural Design The basic aim of structural design of the buildings is to ensure the achievement of satisfactory behavior during the intended design life. With appropriate degree of safety they should sustain all the loads coming during construction and use. Adequate durability and fire resistance are other major factors governing the design.Robustness: Proposed Structures are planned and designed, so that they are not unreasonably Susceptible to effects of accident wherein damage to small area of failure of single element may lead to collapse of major portions of the structure.
  • 20. Serviceability: The design properties of materials and the design loads comply with design codes specified in later part of this report and would typically include:i. Deflection Criteria:Deflection due to vertical loading: Final deflection below level of supports should not be greater than l/250 where l is the span of the member or the length of the cantilever. Deflection after installation of elements such as cladding and partitions not greater than l/500 or 20mm whichever is lesser.ii. Response to wind loads:Limiting the deflection to h/500 under design conditions and the storey drift to 0.04 *Storey height
  • 21. iii. Cracking of concrete: Design surface crack width due to applied loads orthermal or shrinkage effects not greater than 0.3 mm iv. Vibrations: By avoidance of discomfort or alarm to occupants,structural damage or interference with proper functioning v. Durability: Durability is achieved by integration of all aspects ofdesign material and construction technology. Theenvironmental effect to which the concrete or steel isexposed is taken into account during the design byproviding adequate cover to reinforcement and use ofprotective coatings to structural steel works.

  • 41. CONCLUSION The green buildings gives the facility a campus feels, and creates anenvironment of creative thoughts and interaction which will help inexchange of ideas. The design shall also be energy efficient. From the design point of view, the design specifications are to bethoroughly satisfied, since no compromise can be made regarding thestability of the structure. Quality control plays a vital role in the construction of the structure.The quality control department in the site is of major importance.Appropriate precautionary measures are to be taken to avoid the use ofinefficient material. The fire fighting system which can efficiently control the hazardouseffects of sudden fires and which minimizes the loss is importance inthis structure.
  • 42. Safety and security plays a major role, because huge equipment manpower get involved while constructing these kind of huge structures. Therefore, proper formulation of rules and regulations regardingsafety is mandatory. The green building experiences in India have been exciting andchallenging as well. Since its introduction in 2001, the LEED rating hasemerged as a very useful tool in designing a green building. Now there isan imminent need for service providers, who would be required in largenumbers, not in hundreds but thousands, as the movement is heading toreach greater heights. The green building movement is here to stay for the benefit ofindividuals, society and the country at large.
