WM Morrisons, Market Hall, Preston, UK


dpa lighting design worked closely with the lead consultants, Montana Vistas, and the architects, Darnton EGS, on the new concept 80,000 ft² Morrisons supermarket in Preston. The new lighting concept was just one of many new store design features and innovations, creating a new experience in large grocery retail. The main sales floor is split into two distinct areas, the Market Street, containing freshly prepared food from in store specialists including butchers, bakers, cheesemongers, fishmongers and green grocers, and a racking area, predominantly containing boxed and tinned goods. The lighting to the market street area utilised a number of track mounted spotlights providing focused accent lighting onto the product displays. A warm white, energy efficient, LED light source with excellent colour rendering properties was chosen to best reveal the colours of the displayed products. A different lighting concept was chosen for the racking area, where hi-bay pendants were chosen to tie in with the high-racking ware-house style appearance. Energy efficient ceramic metal halide lamps with excellent colour rendering were used to best show the colours of the displayed products, however a cooler white colour lamp was utilised to provide a visual contrast with the warmer appearance Market Street area, subtly indicating to the customer that they are moving into a different area of the supermarket.

A microprocessor lighting control system is utilised to select the correct lighting scene to suit the time of day and year, and the store operational status (morning / day / evening trading, cleaning, stocking, security, etc.). The lighting control system communicates with the supermarket’s building energy management system (BEMS), thereby allowing Morrisons head office to vary the times at which different lighting scenes are selected to suit changing seasonal opening hours. The dimming and switching of luminaires also provides operational energy savings and reduces the frequency of maintenance required.  Photography courtesy of Andrew Depledge
