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. • 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. 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. • 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. 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

8. • 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:

9. • 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.

10. • 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.
