  • Le Terrazze team found a way to improve energy efficiency with operational changes and without any investment needed. Furthermore, they implemented a strategy to keep results over time, even after operational teams have changed.
  • The implemented measures led to electricity savings of around 3%, equivalent to €12,000 per year with no adverse impact on the mall’s comfort and safety levels.
  • Documenting ‘relevant energy events’ (e.g. opening, closure, cleaning schedules etc) which imply different lighting requirements.
  • Defining lighting minimum needs for each of the ‘events’ and establish the links between each BMS control component (BMS buttons) and the circuits controlled.
  • Fine-tuning by defining and setting schedules for each lighting circuit.
  • Defining a Manual with all configurations and activate different BMS access levels to avoid deviations from optimum control by someone without the access to do so.
