The dominant design target of this new office building at the outskirts of Hyderabad was the optimization of maximum shading and maximum use of daylight in order to reduce energy consumption. The proposed solution follows a twin strategy to achieve these conflicting goals. Firstly, the general layout of the courtyard building optimizes orientation and provides maximum fenestration for work spaces in the north and south wings, whereas the east and west wings in which radiation levels are high are occupied by cores. Furthermore the building shape steps out upwardly on its south façades to create self-shading effects. Secondly, the façade design is carefully analyzed to minimize solar heat gain while maintaining views and high daylight levels.

Vertical shading fins on the façade run the full length of the building. The varying but fixed angle of the fins for each orientation is optimized through extensive shading coefficient analyses. To enhance the contributions to a sustainable performance of the building, rainwater is harvested to be used for irrigation and replenishing the aquifer and an onsite sewage treatment plant processes grey water for non-potable use. This project has been commended because it is an outstanding example of a perfectly designed and engineered building that provides a multitude of sound contributions to sustainable construction without using any gimmicks.
