The power of outstanding collaboration is brilliantly demonstrated at John Lewis in York, the first department store in the world to receive BREEAM Outstanding certification.

By working closely with its energy technology suppliers and consultants, John Lewis, York has slashed its absolute carbon emissions by a massive 43.8% compared to the benchmark, almost 14% more savings than the original expectation.

John Lewis has been working with low carbon consultant Lateral Technologies for the past 16 years. For the last seven years, Lateral Technologies has been using the IES Virtual Environment (IESVE) building performance analysis suite to analyse the operational efficiency of John Lewis stores.

In 2012 IES Consulting joined the team to bring its IES-SCAN technology which allowed Lateral Technologies to take operational monitoring and energy management to the next level. IES-SCAN takes data directly from the building management system (BMS) and refines it with the design model to highlight any performance gaps.

Controls company Next Control Systems also joined the team around this time and was responsible for extracting data from the BMS system to share with IES and Lateral Technologies.

Together, this close-knit team assisted John Lewis in the creation of its York store its most sustainable to date and is helping the retailer achieve its target of reducing carbon emissions by 15% across all its stores by 2020.

A number of processes were put in place to ensure the team worked as effectively as possible. For example, Next Control Systems set up an automated email system which emailed data out to Lateral Technologies and IES on a daily basis in a suitable format for uploading to a 3D model.

IES provided the secure cloud server on which to host the data collected by Next Control Systems. The IESVE 3D model was then able to be shared between all parties.

Tasks, data exchange formats, project goals and standards were all agreed on from the outset of the project, enabling an integrated Workflow that was critical to achieving the project requirements.

The IES 3D model was used collaboratively by the whole project team throughout the building's development, from concept to schematic and detailed design onto commissioning and monitoring.
