COSTCO is set to save between 50%-70% in energy costs by using the new Dedham Twin IFan system from Fläkt Woods.
“This will provide Costco a return in investment via the Government’s Enhanced Capital Allowances and offer major contributions to Costco’s energy saving objectives,” says Mark Cox, a partner in Faarup Associates, consultant engineers for Costco for the past five years. Faarup has been tasked with saving more energy via ventilation systems for all future Costco stores.

To achieve these objectives, Faarup looked at several options, including ideas from Fläkt Woods, the manufacturers who provided the extract systems for previous UK stores including Watford, Birmingham, Glasgow, Chester, Sheffield and Milton Keynes. Faarup followed the current environment policy in trying to reduce greenhouse gas emissions at the Costco distribution centres.

“Fläkt units have always provided both durability and ease of maintenance in other Costco stores, so I tasked the company with finding an energy saving solution for the other stores,” says Cox. A solution was found and Fläkt Woods undertook a trial installation of the Dedham Twin IFan at the Watford site to see what energy savings could be obtained. The areas focused on were the customer café, hot chicken rotisserie and the bakery.

Reducing energy consumption via the current extract system, in conjunction with the existing BMS system, incorporating sensory technology, has provided more innovative, energy efficient technologies.

“The results of the trial demonstrate savings of over 50% in the energy required to run the extract fans and offer a payback via ECA to Costco in under two years. Designs for the Cardiff store are underway, where we will use the new Fläkt Woods system again,” continues Cox. Costco is a fast-growing UK retailer and has some 19 locations.
