Major renovation of several shops in Geneva
In 2011, TJCA undertook the renovation and development of a series of the famous food market Denner, in Geneva. Today, we can count the renovation of 30 shops and the work is still going on. The aim was to adapt and improve the energy aspects of the shops with the Geneva’s legislation. So we created a sustainable system to upgrade heat recovery and cooling technologies.
The stores are heated by a fridge heat recovery system and the refrigeration of the sensitive areas is made by a cold water system called in French lac froid. With this sustainable heating and cooling system, the shops are totally autonomous, as there is an internal loop.
