ABOUT

SUPERDRY

Superdry is an exciting contemporary brand which focuses on high-quality products that fuse vintage Americana and Japanese-inspired graphics with a British style. There are 139 owned stores across the UK and mainland Europe, 208 franchised and licensed stores, and 168 concessions and with such a retail portfolio comes the challenges of managing energy consumption and spend.

Challenge

MAXIMISING EFFICIENCY OF EXISTING BUILDING ENERGY MANAGEMENT SYSTEMS

Optimised were commissioned to reduce the energy consumption by 10% in 10 of Superdry's UK stores over a 6-month period. Each of the 10 stores had the latest BEMS (Building Energy Management System) already installed, with remote access. Each store had its main incoming electricity supply metered, along with HVAC sub-meters on the majority. 

It soon became clear that although latest technology had been adopted, these stores still weren’t running as efficiently as they could be and there was an opportunity to ‘optimise’ the operation of the HVAC (Heating, Ventilation and Air Conditioning) and Lighting within the stores.

OPTIMISING BEMS CONTROL STRATEGIES TO STORE PERFORMANCE SPECIFICATION

The first objective was to monitor the energy being consumed through the meters that were already installed into each store. With these meters already being available, this negated any integration requirements. This half hourly data was logged and ‘pushed’ to our cloud-based Automatic Monitoring and Targeting software, which created the transparency and baseline data to effectively monitor and measure the impact of the building optimisation deployed.

The second objective was to implement the BEMS Analytics platform, to monitor the BEMS and HVAC systems through intelligent algorithms and rules. This cloud-based platform tracks the performance of assets, equipment and systems and quickly identifies anomalies in plant operation saving energy and maintenance costs.

Once the above systems were in place, the task of optimising the assets began. This started with analysing the baseline data and energy profiles for each store, to allow us to track energy usage outside of store trading times. This led to our analysts aligning time schedules to match trading times, operating at suitable temperatures during trading periods, without affecting store conditions and shopper experience. We also encouraged the correct use of override switches, and ensuring heating and cooling systems were not operating at the same time, thereby not competing against each other.

Once these foundations were put in place, our Remote Optimisation team took over, to monitor the performance of each store’s HVAC, BEMS and lighting circuits, to ensure continuous operational efficiency and cost savings.
