Restaurant No. 1 reopened on 20 March following the completion of several months of work.

With the exception of some improvements to the decor, most of the work went on behind the scenes, consisting of a complete electrical overhaul, replacement of all the lighting with LEDs and the installation of more energy-efficient and ergonomic equipment.

The heating, ventilation and air conditioning (HVAC) systems have been updated to include an optimised ventilation system and a new heat-recovery heating system, resulting in energy savings equivalent to two-thirds of the required 170 kW total consumption.

All the resource-intensive equipment involving the use of water has also been renovated and optimised, notably in terms of water supply and treatment. All the underfloor ducts were enlarged and covered with custom-made floor plates to seal them off and make it easier to clean the kitchen and service areas.

The work is part of a general sustainability and energy-savings policy. It has also improved working conditions and safety and optimised the use of space, as well as meeting the needs of the restaurants’ users.

Congratulations to everyone who was involved in the project and to the restaurant’s personnel, who adjusted admirably well to the temporary arrangements while the work was in progress.
