case study of INFOSYS MIHAN

  1. 1. CAMPUS FOR INFOSYS LTD.,MIHAN CLIMATOLOGY RAGHVANI DHVANI P. DIV.: B ROLL NO.: 6 L.J.SCHOOL OF ARCHITECTURE L.J. UNIVERSITY, AHMEDABAD
  2. 2. INTRODUCTION: • Project Name: Campus for Infosys Ltd. • Typology: Institutional/Offices • Location: Nagpur, India • Completion Year: In Progress • Client: Infosys • Built-up Area: 8,25,000 Sq.Ft (Phase 1) • Site area: 142.0 Acres • Climate: Composite • Landscape Design: Deep Roots (Rajalakshmi Iyer) • The building will have leverage radiant cooling technology, natural lighting, water recycling and environment friendly material for construction. • This is the third Infosys campus in the state. The other two campuses situated in Pune, began operations in 1996 and 1999 respectively.
  3. 3. • Climatic concerns: • A prototype for innovation in the design of sustainable workplaces: • The plan evolved from the notion of understanding the capacity of the site; • a capacity determined by functions- energy, water, geology of the land, • along with essential rules of urban design pertaining to light, ventilation, shading, etc. • Based on that a masterplan for a working population of 20,000 emerged, to be net zero on Energy, Water and Waste discharge. MASTERPLAN
  4. 4. BUILDING LAYOUT AND ORIENTATION: • A remarkable envelope design • orienting the blocks at ± 22.5 degrees to the North (in response to the solar orientation) • allows for 100% shading of all windows and walls. • 90% of all floor plate areas are designed to be uniformly day-lit and glare-free. • The building volumes were sized based on the lowest common denominator • the design offers full flexibility through largely column free spaces, • the modules are stacked into a four floor format connected through an atrium and staircase, • allowing for slow mode interconnectivity; the enhanced human interaction leading to newer and better ways of thinking and working.
  5. 5. • The landscape design utilizes the existing natural wealth as strong design elements and a smart system of rainwater retention and reuse across the site together with extensive native planting to contribute to the sustainability of the local and wider ecosystem. LANDSCAPE PLANNING:
  6. 6. PASSIVE DESIGN STRATEGIES: • Solar shading: • a typical opening on each of the four orientations (NNW-SSE and NNE-SSW) • it was concluded that 422mm deep vertical fins spaced at 600mm c/c could be adopted for North and North- East orientation • helped maintain views across the entire height of the window while effectively shading the morning sun. • 600mm wide fins spaced at an overall 600mm c/c proved to be optimum for North, North West facing windows. • Solar controls for south façades were designed considering 21st December (winter solstice) for peak design parameters
  7. 7. • Daylight Distribution and Glare Control: • South facing windows suffer more from direct solar radiation for most part of the day. • the high levels of external illuminance could lead to the panel itself becoming extremely bright. • light shelves at 2500mm which obstructed the direct view of the daylight panel from the occupant’s seated level. • For northern orientations, the daylight available is diffused and therefore glare-free. • the addition of internal light shelves on the northern façades which were expected to increase daylight distribution inside the workspace. • Further extending the light shelves by another 600mm towards the outside led to a significant improvement in the daylight levels. PASSIVE DESIGN STRATEGIES:
  8. 8. • Heat gain from solar radiation is based on the solar heat gain factor (SHGC) • the glass which, in turn, depends on the specifications of the glass and on the angle of incidence. • Owing to the solar shading design, the effective SHGC in this case was much lower than the maximum SHGC which played a significant role in reducing the overall heat gain from incident solar radiation. THERMAL EFFICIENCY: • the solar heat gain for the entire building was calculated and resulted in an overall thermal efficiency of 0.79W/sq. Ft.
  9. 9. • 15 acre solar plant, giving complete independence from the grid. • Zero Water dependence is achieved by calculating the rainfall on site, how much could be realistically harvested, creating a reservoir to that capacity, simultaneously ensuring that all systems are designed to the greatest efficiency, such that the water consumption per person is 50% of baseline. • Biological waste is to be dealt with on site through a bio-gas plant. WATER EFFICIENCY:
