Olympia Technology Park

Olympia Technology Park, Chennai, the largest certified LEED gold-rated green building in the world under the CS category. The largest monolithic IT Park in Chennai, covering 1.8 million sq. ft. of total area; this is nearly 30% larger than the second biggest such facility in Chennai.

Shortest commissioning tenure for any such multi-tenanted IT facility in India.

Extraordinary features of the system:

• Actuator provided to control the chilled water flow and save energy.
• Ultra sonic BTU meter to calculate the thermal energy.
• Stairwell pressurization system which aid during emergencies.
• The condensate water collected from the AHU 40 kL per day.

Quantifiable and tangible benefits resuming from the innovation (give in metrics of Quantification).

• BTU billing software implemented for precise billing for the occupants at OLYMPIA.
• Double glazed structure with Aerocon blocks as measure to confine heat and to provide a better ambiance at the work place.
• Individual CO2 sensors provided for the conditioned in each AHU area in the return air. So as to control and monitor the CO2 level which meet the Green Building standards set by ASHRAE.
  
• International and domestic standards met by the system design. 20 CFM of fresh air as per ASHRAE standards.
• Design of air-conditioning systems in accordance with ASHRAE 90.1-2004.
• Solar orientation to maximize north and east exposure and minimize the south and west exposure.
• Low U-value roof as per ASHRAE 90.1-2004.
• Fenestration maximized on the north orientation to minimize heat gains from windows and also to maximize daylight.
• Low-U glass glazing
• Designed LPD (lighting power density) of 0.8 w/esq.
• Energy efficient motors.
• Use of aerated autoclave concrete blocks.
• Intelligent building management systems.
• Installation of carbon dioxide sensors to monitor indoor air quality.
• Internal room comfort at 730 F ± 2 and RH not exceeding 60 % as against a prevailing norm of 73°F ± 2 and RH not exceeding 65%.
• Planned indoor fresh air quality at 20 CFM per person (ASHRAE Standards) as against the prevailing norm of 15 CFM.
  CO2 sensors to monitor indoor air quality and replace stale CO2 - laden air with a fresh in-draught whenever CO2 exceeded a certain level.
• Air replacement cycle adapted to the number of people present in the indoor area; when the number of people declined, the sensors monitored this accordingly and slowed down the air replacement frequency from five per hour to two per hour and vice versa.

Conclusion: Thus 20% annual savings in energy costs.
