Brandix says it was the first time in the world that an apparel factory had received a 'platinum' rating from the certification body.
The plant was converted at a cost of 3 million US dollars to reduce carbon emissions by 80 percent, achieve energy savings of 46 percent and water saving of 58 percent and zero sold waste for landfills.
"The fact that it is a global first for us, our country and the apparel industry worldwide, makes it all the more significant, and is a huge shot in the arm for our apparel sector…" Brandix director AJ Johnpillai was quoted as saying in a statement.
"This is also a tribute to the local engineering skills available and in particular to our consultants EnergySolve International…"
Brandix says its factory scored 76 points 12 points higher than the 64 required to win a platinum rating.
Brandix say the energy conservation was achieved with air-conditioning, which is a requirement for a platinum rating.
Air-conditioning made up 70 per cent of the energy consumed in a garment factory.Brandix says it bought a screw-type chiller unit patented in the US to provide energy-efficient air-conditioning for the factory.
Square ducts were converted to round ducts to reduce distribution losses, with 75 millimeter insulation. Heat-reflective panels were put on the roof.
The windows were enlarged to provide more light and a better view out to workers, and fitted with glass with a high solar reflective index.
Prismatic material used for skylights in the roof allowed light to pass through without heat. Natural lights were supplemented by light emitting diodes (LEDs).
The factory has rain water harvesting and recycling facilities. It has 100 percent solid waste re-use program with even food waste being composed and used for biogas generation.
Green areas in the gardens have been increased to provide a green view to occupants, and transport within the premises is by zero emission electric car.
The company says an advanced intelligent building management system controls humidity and carbon dioxide levels to improve comfort levels for workers.
Brandix has 25 factories and has been named the largest apparel exporter by the island's export promotion office.
Brandix makes clothes for Gap, Marks & Spencer, Victoria’s Secret, NEXT, Lands End, Ann Taylor, Abercrombie & Fitch and Tommy Hilfiger.
