Operation Context

Rives d'Arcins is a 20,824 m² shopping center in the Bordeaux metropolitan area, owned and operated by Klépierre. Through participation in the 2023 CUBE competition, the center achieved 37.6% energy savings, placing second in the shopping-center category and eighth overall.

This reduction was driven by a combination of technical upgrades, such as HVAC setpoint adjustments, a full LED lighting retrofit with motion detectors, nighttime shutdown of air handling units, the replacement of the cooling towers, and more. On the usage side, Klépierre's group-level communications team supported the rollout, and a dedicated site project team ran technical tours, feedback meetings, and awareness campaigns to keep occupants engaged. 

Key measures implemented

The main actions implemented to reduce the energy consumption of this building.

Efficiency Investments

  • Conversion to zone LED lighting throughout the building and
  • Installation of motion sensors for lighting. 
  • Replacement of cooling towers.

Technical Optimization

  • Optimization of temperature settings (17 degrees from 10 a.m. to 6 p.m. in winter and 27 degrees in summer) and of constant-temperature loop flow. 
  • Shutting down air handling units at night, reduced operation during the day. 
  • Analysis of parking lot traffic: allowing for the closure of the second level on Mondays and Fridays. 
  • Shutdown of hot water in restrooms

Use Sufficiency

  • Formation of a project team comprising staff members, the operations technician, and the technical officer.
  • Support and involvement from the Klépierre Group’s communications department.
  • Implementation of a communications strategy through email campaigns and newsletters.
  • Launch of awareness-raising initiatives through tours of technical facilities and feedback meetings with teams to identify areas for improvement.
