  6. 6. Path 1Integrated design approachit is possible to apply green materials and advanced technologies inthe building design projects to consume less energy. Buildingdesign for green buildings involves many professionals acrossdifferent areas. Many factors need to be taken into account,including climate, building share, comfort levels, material andsystems, and health.Integrated building design requires all participants includingowners, architects, engineers and others involve at the early phaseof the building project. Building energy performance depends notonly on the performance of an individual technology but also onHow these perform as an integrated system.
  7. 7. Figure illustrates the interrelationships among the four maininfluences on energy efficiency and the key energy consumers.Researches says that integrated design approaches will achievethe best performance in terms of energy saving. Integrateddesign approaches could reduce energy use by as much as 72%.Integrated design approach through BIMAn innovative new approach to building design, construction,And management.Building information modeling supports the continuous andimmediate availability of project design scope, schedule, and costinformation that is high quality, reliable, integrated, and fullycoordinated.

  27. 27. CASE STUDY-4LBHS College, MumbaiLBHS is an architecture collegesituated in the suburbs of Mumbai, in India. It is a prime example ofGreen Building Architecture.The city of Bombay is a bit crowded,and as such, land is at a premium.So, the location provides enoughspace for expansion and providing sufficient infrastructure to students. SITE PLAN
  28. 28. This project is special because it has implemented many energy-saving devices and techniques to make it one of the first green building designs in India. From light sensors for auto-switching of lights, to water recycling, use of solar arrays and use of earth air tunnels, this project has done everything. The designers have aimed at developing a semi- autonomous building, almost self-sufficient building complex. E X H I B I T I O N B L O C K
  29. 29. The interesting feature of project apart from site planning & material use is provision of Earth Air Tunnel to cool down temperatures during the summer season, in order to reduce energy costs.Earth- air tunnels may be considered as special types of wind towersconnected to an underground tunnel. The cooling process is based on thefact that the temperature a few meters below the ground is almost constantthroughout the year. A wind tower isconnected to the underground tunnel,which runs from the bottom of thewind tower tothe basement of the building. The wind tower catchesthe wind which is forced down the tower into the tunnel. Thetemperature of the tunnel, being lower than that of the ambienttemperature, cools the air before it is circulated into the livingspace.

A 30mm translucent polycarbonate panel is installed in between whichhas intelligent light controllers.These louvers have an opaque reflectivesurface. The atrium and preconventionspaces experience the luminous effect brought by this system.
  31. 31. Hybrid fiber optics uniformly distributes sunlight through asingle point source. This technology uses rooftop mounted 1200mmdiameter collector and secondary mirror to track the sunthroughout the day. A single holder holds 127 individual fibers each3mm in diameter.The collector system focuses the sunlight into 127 optical fibersconnected to hybrid light fixtures equipped with diffusion rodsvisually similar to fluorescent light bulbs. These rods spread light inall directions, one collector powers 8-12 hybrid light fixtures whichcan illuminate an area of about 30-40 sqm.Earth air tunnel
  32. 32. 1. The significance of this category is to encourage architects, engineers, planners & developers to innovate new strategies & technologies in the field of green building construction.2. Also it encourage people to not limit themselves the green building criteria determined by LEED INDIA but further enhance their projects beyond the limits.3. New technologies and products are coming into the marketplace, and innovative designs are proving their effectiveness.4. If this category is achieved than more environment friendly structures will come having higher energy efficiency as compared to others.5. But in present scenario these projects are not economic viable because of the high construction cost & lack of skilled workmanship.
