Wirth Research’s Computational Fluid Dynamics (CFD) services can help our clients better understand how to improve energy efficiency within the supermarket environment.

WR store modelling services combine the expertise from wind microclimate studies, natural ventilation and refrigeration to create a virtual model of the store within its real-world environment. A three-dimensional model for the store internals, site and surrounding terrain, combined with realistic atmospheric boundary and store HVAC&R component control allows a step change in store performance understanding. The WR store model provides customer comfort measurements along with energy usage predictions for all modelled systems within the store. Clients can understand the impact of atmospheric temperature, wind speed and direction will affect the store environment, fridge performance and HVAC performance.

Store Modelling: Investigate Problem Stores

This virtual store can be correlated to real world data to recreate issues within a problem store. The level of detail and accuracy within the model allows for problem diagnosis, mitigation investigation and solutions.

Typical issues could include:

  • HVAC issues
  • Refrigeration issues
  • Customer/staff comfort issues

Store Modelling: Supplier Sub Selection

The virtual store is used to compare supplier sub components and systems for minimum energy usage and maximum customer comfort.

Typical supplier sub selection could include:

  • HVAC solutions comparison
  • HVAC control approaches
  • Refrigeration cabinet technology comparison

Store Modelling: Design and Optimisation

The virtual store is used to test design concept decisions prior to any large-scale investment. This allows a step change in client understanding of store performance from an energy and customer comfort perspective.

Typical design concepts tested include:

  • Store orientation
  • Store configuration and layout
  • Best lobby option per site
  • HVAC layout
  • HVAC control
