SITE DESCRIPTION

LOCATION: Marathahalli, Outer Ring Road, Bangalore, Karnataka.

AREA: 7.96 acres.

Site’s northern boundary edge is the nala. This gives a barrier in viewpoint and activities. But can be intervene for opportunity of interactive open spaces in the design.

The site is opened mainly from western side only. A kaccha road is there at eastern side which can be used as service road. The site is accessed from NH 44.

PROJECT BRIEF

ORACLE INDIA PVT. LTD. has planned to open its campus outside the US in Bangalore, marking a significant investment by the US-based online retailer in one of its fastest growing markets. Spanning 8 acres, the state-of-art campus will have ‘thousands’ of employees managing back-end operations of Oracle’s global businesses.

The design for Oracle’s corporate campus creates an integrated and sustainable vision of merging landscape and architecture to create a new form of symbiotic living and working. The building’s design will directly responds to the site’s climate, rich cultural heritage and clients’s goal of further elevating itself as a global leader in business consulting. IT, software engineering and outsourcing services.

SITE ANALYSIS

GEOGRAPHICAL FEATURES

1. The top soil of 0.3m is non-uniform.

2. The underlying layer is laterite upto 2.5 to 6.0m followed by disintegrated rock.

3. At some locations medium rock was met with at depths varying from 11.0 to 14.0 m. At other locations even at 15.0m medium rock was not met with.

4. No water table was met with in the boreholes at the time of exploration. However, perched water table is likely to occur during rainy season.

5. For the proposed structure shallow foundations can be given at any depth from 1.5m, resting the foundation on the late-rite / disintegrated rock layer.

CONCEPT

CONTEMPORARY GARDEN

‘Once called the "Garden City of India", this is no longer applicable to Bangalore, which is now a large, cosmopolitan city with diminishing green spaces and a large working population.’ This change is evident by the changing climate and environment quality.

LAND SUSTAINABILITY

Bengaluru is one of India’s most progressive and developed cities, blessed with a pleasant climate. The past decade has seen a mad surge of development, coupled with traffic congestion and rising pollution levels. The space is being compromised as IT buildings are coming up on very acre of land and the green belt is depleting at a very high rate. Hence, the cost ability to improve adverse condition has decreased due to shortage of land and the opportunity of taking up the garden vertically rises.

1. BROAD CONCEPT

2. FORM EVOLUTION

3. VERTICAL STACKING

4. TREE THEORY TO DESIGN BUILDING

‘The building is designed to be like a tree’ with strong and heavy roots that has all services incorporated and the ‘rest of the levels are projecting out like branches of the tree, holding the foliage’.

Structure of the building is compared to a tree as; the basement is root where main service functioning takes place, the cantilever act as branches to take in natural sunlight and finally the bio wall acts leaves foliage that are also prevents heat to enter and regulates temperature within the building.

DETAIL 1 - Facade System

Sections

Double plane glass with outer glass is Transparent Luminescent Solar Concentrator (TLSC) and inner glass is Electric Glass.

Switch Glass: Layer of film between two glass.

1. very durable

2. can be used as projector screen

3. can last for 15 - 20 years

4. 98% UV protection

5. 40% solar reduction

EXHAUST AIR FACADE

To collect air from tower office, and instead of allowing it to escape into the atmosphere, redirect it back down the double glass skin cavities. Sensors within cavities will modulate dampers at the top of the building, directing the air to the optimal zones of the cavities depending on the time of day and outdoor temperature.

45 degree Celsius - 30 degree Celsius

Additional dampers will allow filtered exterior air to enter directly into cavity during economizing periods, such as at night and winter when the outdoor air is lower in temperature then the collected exhaust air.

DETAIL 2 - Introducing Daylight at any Time

This is a day lighting system that collects natural light with a parabolic dish concentrator and delivers it through pipes to any place in the building. the collector re-directs the light into an “ULTRA SUN LIGHT CONCENTRATOR”, which channels it into the aperture of a small light pipe. because of the latest technology uses “I.R. CUT COATING TECHNOLOGY, there is no heat loss or gain associated with the transmitted day light”, which reduces heating and air-conditioning cost.

DETAIL 4 - Truss System used in Structure

There are two ties in the back-span of the truss. the top and the bottom slab will be acting as a chord and tie of the truss respectively . these trusses are definitely located on both the sides of the slab.

DETAIL 5 - Air Purifying Plants

SPECIAL MATERIAL - Hemcrete

TRADITIONAL HEMCRETE is a bio-composite, thermal walling material from ‘hemp’, ‘lime’ and ‘water’. CARBON NEGATIVE HEMP.

About 40% of the total site is covered with green collaboration areas to reduce the sun reflections and radiation. Also, these collaboration areas caters the social life among the employees working here. Employees can interact among themselves here, play sports for recreational purposes to release stress due to work.

Oracle Office Building - Outdoor Collaboration Spaces

East and west facade receives highest solar radiation and heat as the sun is very low in these two directions. therefore the idea of providing service cores on facade facing these direction came into existence. To minimize the solar heat gain (SHG), vertical bio wall perfectly blends on the concrete wall. this enhance the the idea that there is very less land available

BOX CANTILEVERS are projecting out from the typical floor plates at the length of 14.5 m. The cantilever are simply supported through very simpler structure tricks. The roof of the cantilevers are proposed as green breakout area on every floor to minimize the solar heat radiation and monotonous office life.
