requirements.

Path 1 Integrated design approach

it is possible to apply green materials and advanced technologies in

the building design projects to consume less energy. Building

design for green buildings involves many professionals across

different areas. Many factors need to be taken into account,

including climate, building share, comfort levels, material and

systems, and health.

Integrated building design requires all participants including

owners, architects, engineers and others involve at the early phase

of the building project. Building energy performance depends not

only on the performance of an individual technology but also on

How these perform as an integrated system.

Figure illustrates the interrelationships among the four main influences on energy efficiency and the key energy consumers.Researches says that integrated design approaches will achievethe best performance in terms of energy saving. Integrated design 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 and immediate availability of project design scope, schedule, and cost information that is high quality, reliable, integrated, and fully coordinated.

Integrated design approach – how we do it

CASE STUDY-4LBHS College, Mumbai LBHS is an architecture college

situated in the suburbs of Mumbai,

in India. It is a prime example of

Green Building  Architecture.

The city of Bombay is a bit crowded,

and as such, land is at a premium.

So, the location provides enough

space for expansion and providing

sufficient infrastructure to students. SITE PLAN

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

XHIBITION

BLOCK

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 towers connected to an underground tunnel. The cooling process is based on the fact that the temperature a few meters below the ground is almost constant throughout the year. A wind tower is connected to the underground tunnel, which runs from the bottom of the wind 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.

CASE STUDY-5Thiagaraj Convention Center ,ChennaiSpecial FeaturesControl light system, a glass

technology that produces uniform

lighting throughout the year.

A 30mm translucent polycarbonate

panel is installed in between which

has intelligent light controllers.

These louvers have an opaque reflective

surface. The atrium and preconvention

spaces experience the luminous effect brought by this system.

Hybrid fiber optics uniformly distributes sunlight through a single point source. This technology uses rooftop mounted 1200mm diameter collector and secondary mirror to track the sun throughout the day. A single holder holds 127 individual fibers each 3mm in diameter.The collector system focuses the sunlight into 127 optical fibers connected to hybrid light fixtures equipped with diffusion rods visually similar to fluorescent light bulbs. These rods spread light in all directions, one collector powers 8-12 hybrid light fixtures which can illuminate an area of about 30-40 sqm. Earth air tunnel

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.
