  1. Numerous passive design concepts and strategies evolved using simulation techniques.
  2. Daylighting simulation was conducted to ensure the optimum natural light via glazing system.
  3. The complete air-conditioning system was made to work on solar energy.
  4. Temperature, humidity, glare and adjustable task lighting to optimum levels enabled
  5. Recycled and rapidly renewable material requirements of the LEED Rating system far exceeded in material selection
  6. Green power generated using Solar PV and micro wind turbines, thus reducing the burden on the external grid.

In the year 2009, Turbo Energy Limited’s (TEL) ‘R&D and Administration Block’, at Paiyanur, Chennai achieved the highest points 62/ 69, under the USGBC LEED – NC v2.2, thus becoming the second greenest building in the world after ‘Dockside Green’ Project Phase I – Synergy project in British Columbia with 63 Points in the same year.
  2. The project got Full Points (17/17) in the energy and atmosphere category of the LEED Rating system, with a saving of 48% in energy consumption over ASHRAE.
  3. The energy saved due to passive architectural design was 5.2% of the overall energy consumption of the building on ASHRAE baseline.
  4. The project also achieved Full Points in Water Efficiency and Indoor Environment Quality.
