DECATHLON, Retail Store
The French sports retail powerhouse Decathlon has exploded out of the starting blocks in South Africa. Founded in 1976 and recently voted France’s best-loved brand, the company opened its first two stores in South Africa in 2017, with a rollout to follow.
The forward thinking brand were keen to carry this innovation into their new stores, to make them as energy efficient as possible by introducing natural light. To maximise this energy saving, Decathlon approached Triac to design a lighting control system that would measure the natural daylight entering the building and reduce artificial lighting accordingly. This concept, also referred to as ‘daylight harvesting’ , balancing natural and daylight is proven to offer substantial energy savings, reduced heat load, and reduced luminaire maintenance. This translated into a 15 -20% month on month reduction in energy costs for Decathlon, and an excellent and measurable ROI.
Triac designed a DALI control system, that could be addresses and reconfigured to match direction of the racking system. The system could be then be calibrated according to the required light levels according to the light entering the store from the clerestory windows.
Prewired, and pre-tested Lighting Control Panels made for a quick and easy installation, reducing the amount of work required by the electrical contractor as possible. This robust solution offered the required flexibility and simplicity for easy and quick deployment. The system was also integrated with the fire alarm and security system for seamless interoperability with other building systems.
The system has been set up to give the store 32 different presets to allow fully automated control of individual and grouped areas. Eight lighting scenes have also been programmed into the system for general lighting requirement, according to a scheduled timetable designated by Decathlon
It was important for Decathlon to match lighting levels and energy savings with group lighting standards for its stores globally.
The Triac lighting system solution delivered to the new Decathlon flagship stores saves over 60 per cent of the energy used for lighting compared with standard lighting solutions. This is expected to reduce carbon dioxide emissions by an impressive 96 tonnes per year. Decahtlon is extremely happy with the finished result, both in terms of the ongoing energy savings it can enjoy and the quality of lighting provided in this flagship store. Added to this, the company can expect additional sizeable reductions in its annual maintenance costs, simply through not having to replace lamps and drivers. In all, this has been a very successful project for both Triac and Decathlon, providing a template for the lighting design of future Decahtlon projects.
