Wind driven roof ventilators have been in existence for over 3 decades. Developed in the USA, where it is primarily used as an attic /domestic ventilator, the roof ventilators have found a more industrial application in India considering the higher throat dia and material of construction. Evaporative cooling systems can be used for cooling at a fraction of the cost of conventional air conditioning systems. If used in a correct manner its ideal for sustainable and energy efficient comfort as well as process conditioning requirements. The ECS used for the case studies in this paper are systems that deliver higher air volume with lower energy consumption. Fabric Air Dispersion Systems were used for their lower carbon footprint and the fact that they can be removed and cleaned. Combining a precise ECS with WRV and using fabric ducts for delivery, an energy efficient system can be designed with perfect air balancing, optimum airflow patterns and utmost effectiveness to provide the necessary conditions in all parts of the building.
