Fans still contribute to a considerable share in the domestic and commercial sectors, although in the commercial sector air-conditioning is a preferred option owing to economic development. On average, fans contribute by about 7 – 8% to energy consumption in offices of the Government sector, while the average domestic consumption of fans is 8.3 kWh/ household per month. Ceiling fans are widespread in the domestic sector, which contribute by a considerably higher energy usage than the table/pedestal types. After identifying the importance of contribution of the ceiling fans to the national energy consumption, the SEA, with the assistance of SLSI developed a standard (SLS1600:2011) for fan labelling and accordingly, a Regulation was passed in 2013 in the parliament to ban the inefficient fans from entering the market. It has been estimated that 298.3 GWh of electricity can be saved by implementing this scheme by 2020.
The SEA has initiated the procurement of fan testing laboratory which will be ready by the end of 2017.
A test facility for testing energy performance of ceiling fans is currently being installed at the Sri Lanka Standards Institution (SLSI). Air flow velocity, as well as electrical characteristics such as electrical power consumption and power factor of Ceiling fans will be tested at the test laboratory.
