It is the world’s best example of passive architectural design. It was the first building outside of us which has been awarded LEED platinum rating at the time of its inauguration. And, the unique feature of this building is, it does not let out any waste and recycles it all within. Here are the points which make this one of the best green buildings in India:

  • Courtyards– The courtyards act as “light wells,” illuminating adjacent work areas. When this light is not sufficient, sensors trigger the deployment of efficient electric lights. And, the Dimmers automatically control the illumination levels, turning the lights off when they’re unnecessary. Also, occupancy sensors prevent light from being switch on at an unoccupied workstation.
  • Internal Lighting– The courtyard may be hot because of the temperature as a result the cool air replaces it. Also, the hot air being lighter than cold air rises up making the place cooler and above the terrace gardens keep the temperature down forcing the hot air to rise up further.
  • Roof Garden- Absorption of heat and radiating it into the building. Minimization through the roof gardens covering 55% of the roof area. And Seepage into the ground has been installed in pedestrian areas and parking.
  • Natural Lighting– Natural light deflection systems can direct light deep into the room and ensure better natural lighting provisions.
  • Reflective glass (mirror)– This material reduces the penetration of radiation from the reflecting side to the non-reflecting side (penetration of 11-37% of total striking radiation). Such glazing is used in this building where it is desirable to maintain eye contact with the outside as well as to prevent penetration of radiation and in areas where it is hot most days of the year.
