Sustainability Through Innovation

Mindtree Kalinga

Mindtree intended the campus to be sustainable in terms of its water and energy consumption by pursuing benchmarks of a LEED platinum rated building. As design and sustainability consultants, we have developed a completely water self sufficient campus and designed an efficient Heating, Ventilation and Air Conditioning system.

The use of stack effect enables natural air flow in the building. Stack effect is a ventilation system that takes advantage of the building physics to remove hot air and allow entry of fresh cool air. An atrium of 300 square feet is provided on the terrace, which captures sunlight and heats the air. The hot air rises up due to low pressure and escapes out of the building. There is a vacuum created in the building due to removal of air, this forces cool air to enter the building. Shafts are placed in strategic locations which connect the rooms to the central atrium.

How do we better the base case?

The total EPI (Energy Performance Index) is reduced to 91 compared to 150 of a conventional building. All the techniques used in designing the Mindtree campus have helped it achieve the LEED platinum rating. Thus the impact of the building on the environment has been reduced and McD BERL has been a vital part of this achievement.

what did we do?

The building also has windows and shading devices to achieve maximum daylight. This decreases the lighting load by 70 percent. The remaining of the light required is provided by using T-5 and LED lights these fixtures reduce lighting load by 30 percent compared to a conventional building.
