10. S.No SEIAA Observations TRIL Response
Fundamental Observation :
i In the EC issued, Basement 3 not included but
constructed at site.
We have obtained approval for parking of
6,247 cars and 12,131 two wheeler parking as
well as 25 bus parking within campus, for
which we have obtained EC for basement 1 and
2, Stilt level and the remaining as surface
parking.
During construction, we have provided one
more additional basement and stilt level for
parking, to avoid heat island effect due to open
parking planned earlier.
ii EC was issued for only 1 – IT block, but 4 IT
blocks constructed.
We wish to clarify that it is an IT Park
comprising of the blocks A,B,C,&D as per our
initial application and presentation to the
committee
iii EC was issued only to have Retail shop with
Basement -1, G.F and 3 floors, where as 13
floors are constructed.

24. Organic Waste Converter (OWC)
“ The Organic Waste is converted into homogenized
odour free output within 20 minutes through Bio
Mechanical Process and is converted into COMPOST
within two weeks which can be used in gardens and
landscape applications. With this system we are
effectively disposing food waste scientifically there
by reducing landfill burden to that extent. We are
collecting the food waste from our Food court and all
our tenants cafeteria. The waste segregation is
initiated at primary collection stage itself to use the
waste effectively. As an average we generate 100 to
150 kg per day from our waste. We have a separate
trained team in roll to take up the service daily”

32. Flood and natural disaster management /
Earth Quake Resistance
1. Ramanujan IT City has been designed in accordance to the standard codes IS 456
and IS 875 for structure and other imposed loads.
2. For Seismic structural stability it has been designed in accordance to the code
IS 1893:2002 for Zone – III criteria.
3. The Chennai Disaster resilience report classifies our site in Zone X, Wherein, the
overall resilience is slightly above average.
4. The Flood risk areas in this Zone is Velachery which is 5 Kms from the site and
Adyar which is 3 kms away.
5. The site is also located at 2.25 Kms from the Coastal Regulatory Zone (CRZ)
6. The approach road – OMR is at a height of +4.1 m above MSL (Main sea level). The
internal roads are at +5.0 m above MSL (0.9 m above road level) and the ground
level is at +5.52m (1.4 above road) hence suitable precautions have been taken
while designing this campus to mitigate floods. The site is also equipped with
suitable storm water drains on the periphery.
7. The habitable area starts with the Amenity level which is at +11.82 m above MSL
(7.7 m above road level) hence more safety for the occupants.
33. Site Photographs during
Monsoons
Entry Gate & Internal Roads during heavy
rains in Dec’ 2015:
• No water stagnation inside the site.
• All Terrace & Surface water run offs
were managed by collection & proper
drain network.
40. Landscape Features
Landscape has played a major part in reducing
the Heat Island effect in the campus
Major portion of the podium area is covered
with greenery thereby reducing the heat
transmission to the lower floors and glare on to
the façade
In the Ground floor too care has been taken to
reduce the glare with extensive vertical
landscaped compound wall and planters along
the entire stretch
The top soil had been preserved at site during
excavation and same has been used for
landscape in site
Care has been taken in choosing native species
of plants thereby reducing the water
requirement and survival of same.
41. Landscape Features
Recycled water from STP is used for
landscape water requirement
Sprinklers have been installed to minimize
wastage of water
Recycling of water in water bodies has also
helped in reducing the water consumption
in landscape
More than 90 % of the cars are located
under cover in basements.
Care has been taken in choosing trees in
Ground level to see to it the same takes not
more than 5 years to grow full height and
give adequate cover to the open car parks
located in the external areas, thereby
reducing the Heat Island effect .
42. Parking
- 5 Levels of ample car parking – Reduces heat island effect as a result of covered car park
- Epoxy flooring to reduce wear and tear
43. • Rain water harvesting percolation pit with over flow connection to the system with
micro filter.
• STP has been designed to handle 100% waste water from the campus.
• Water efficient flush & flow fixtures have been adopted.
• Water recycling using treated water for the Toilet flush, landscape balance for the
cooling tower make up ,drift and evaporation losses (sewage recycled to the extent of
95 % )
• Variable speed secondary / tertiary pumps which ensure that chilled water is supplied
according to demand.

52. Cooling tower selection for minimum drift and noise level
VFD for motor speed control.
Heat recovery wheels for pre cooling fresh air by using the waste exhaust air
from toilet etc., This ensures energy conservation in green buildings despite
of higher fresh air intake (i.e., In green buildings 30% more fresh air needs to
be supplied in all breathing zones to meet increased ventilation credit)
• Motorized damper for the fresh air to operate based on CO2 sensor.
• High COP (Low IKW / TR) Water chilling machines.
• CFC & HCFC free system used in all HVAC & fire suppression.

- Electrical
• Energy efficient fluorescent tube lights (T-5) shall be used.
• All fluorescent light fixtures are specified to incorporate electronic chokes
which have less watt-loss compared to electro-magnetic chokes and result in
superior operating power factor. This indirectly saves energy. Electronic chokes
also improves life of the fluorescent lamps.
• Energy efficient fluorescent lamps & CFL lamps which give approx. 30% more
light output for the same watts consumed and therefore require less nos. of
fixtures and corresponding lower point wiring costs.
• An APFC relay based on contactor switching is proposed to effect the power
factor correction / improvement.
