The Co-Ownerships Association of “ZAC du Lay” is an association that unites the owners of five separate co-owned properties in Contamines Montjoie, Haute-Savoie, France.

The challenge :Significantly improve the service quality and the comfort of the residents

Les Contamines

By instigating a complete overhaul of its infrastructure, the Association of “ZAC du Lay” seeks to improve the quality of outdoor lighting in the five co-owned properties.
Also, by equipping areas that previously had no lighting and readjusting the level of lighting in
other areas close to the apartments, the Association wants to increase the comfort and well-being of all its residents.

The Association therefore began a general renovation of its lighting infrastructure. Initially, it chose to be guided by a specialist consultancy in order to draw-up an inventory of the existing installations and provide an initial cost estimate for all the works. Based on the information in this report, the Association decided to resume the project’s management directly, whilst also relying on the expertise of a local installer: GRAMARI, a subsidiary of the FIRALP Group. A decision was made to renew the entire equipment, with LED light
fixtures and installing new lighting points in identified areas.

As the project advanced, a new need appeared: lighting according to need without ever being in total darkness. The Association wanted to adjust the lighting to the movement of residents, to ensure an optimal level of comfort and well-being without wasting energy.

Amongst other things, it is responsible for maintaining service roads, outdoor car parks, green spaces and snow clearing, as well as outdoor lighting. The lighting infrastructure of the Association has not been renovated since it was first installed in 1985. It includes 53 lighting points, most of which are spherical light fixtures, with mercury-vapour lamps,
some of which no longer worked.

SensyCity® represents ease of useFor example, following the first programming, we found that the boost lighting was too powerful, but we were able to change it the very next day, there is a margin for error. And the application makes things easy as it is so user-friendly.
