Building functions can be zoned according to ventilation strategy for effective management and energy conservation. This is seen in Akshay Urja Bhavan, New Delhi where spaces are divided into zones according to setpoints– Apex, Controlled and Passive. Only around 12% of the area is air-conditioned. Mist cooling systems are used for the Controlled and Passive zones1.

This would then be taken through precipitators to eliminate dust and would be supplied to the building through ducts. The result! – Pleasant 25oC temperatures indoors, without the use of air-conditioning, when temperatures outside are nearing 50oC1.
