10 Observations as per SEIAA dt. 04/08/2014 & TRIL Response S.No SEIAA Observations i ii iii Fundamental Observation : In the EC issued, Basement 3 not included but constructed at site. EC was issued for only 1 IT block, but 4 IT blocks constructed. EC was issued only to have Retail shop with Basement -1, G.F and 3 floors, where as 13 floors are constructed. TRIL Response 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. 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 Non-Processing Zone consisting of Hotel, Retail and Residential has not yet been constructed. Besides our revised amendment application dt was made for amendment of product mix from Retail / Residential to office towers.

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 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 ENERGY CONSERVATION MEASURES Water Recycling 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.

50 ENERGY CONSERVATION MEASURES -Architectural Hollow block for wall construction Energy efficient Façade design with composite ACP cladding (U- Value 0.14 Btu/hr ft 2 F) Covered Parking Window Wall ratio of 30% Over deck XPS Insulation Double Glazed Unitised glazing (U-Value 0.32 Btu/hr ft 2 F) Punch windows on East & West Direction to control Heat radiation Strip glazing on North & South for Efficient Day lighting Centralised Services in Utility block Three basement & two stilt covered parking for the vehicles. Providing separate smoking provision away from building, maintaining building as nonsmoking zone

51 Façade Design Punched windows on the East and West To control heat radiation Glazing on the North and South to allow maximum day light

52 ENERGY CONSERVATION MEASURES HVAC 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. CO sensors for the basement ventilation fans.

53 Indoor Air Quality Intent Prevent Indoor Air Quality problems Enhance indoor air quality Comfort Good IAQ can enhance Occupant productivity by 5-15% Well-being of the occupants Area cfm per person cfm per sq.ft Office space RITC CFM 30 % more than ASHRAE standards

54 Indoor Air Monitoring CO2 Monitoring All densely occupied spaces CO2 locations between 3 and 6 above the floor RECOMMENDED CO2 LEVEL BY ASHRAE 1000PPM Non-densely occupied spaces A direct outdoor air-flow measurement Minimum air flow should be as per AHRAE Increase air ventilation rates to all occupied spaces by at least 30% above the minimum rate required by ASHRAE

55 Space Environment MERV Filters MERV Minimum Efficiency Reporting Value A number from 1 to 16 relative to an air filter s efficiency. The higher the MERV, the more efficient the air filters is in capturing particles.

57 Energy Conservation Measures Air-conditioning Provided Water Cooled Chiller with higher COP Water cooled chiller - energy consumption less than Air cooled Chiller Recycled water to Cooling Tower Energy efficient motors POWER CONSUMPTION 10% 1% 89% AC LIFE CYCLE COST 0.65 KW/TR 1.3 KW/TR Operating Cost Intial Inv. Maintainenance / Consumables

58 Energy Conservation Measures - 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.
