Installation on May 30, 2018 of a weather station, surface temperature sensors and soffit.
Description of the operation: A coating Cool Roof France was implemented on 18 000 m² of roof of the hypermarket and the gallery of the Casino Valence Sud to reduce the energy expenditure of the building.
Results:
• The surface temperature is reduced by 4.98 ° C on average with reduced maximums of 36 ° C
• Maintaining temperature setpoints despite 5 roof top (out of 10) down
• The overall energy consumption of the building has been reduced by 12% or 20.5kWh / m² / year
Sustainable development approach of the project owner

Cool Roof offers an innovative ecological reflective thermal paint, which reflects the heat. Environmentally friendly, it is light, resistant and easily applied to all types of roofs. A white roof "Cool Roof" returns the heat of the sun, thus limiting the heat on the roof of the building, and thus inside the building. The building manager can: - save up to 30% energy - plug the roof microcracks - all without having to modify the structure of his building
Owners of large commercial, industrial or institutional buildings seek this kind of simple, affordable, direct energy efficiency solution, thus avoiding overloading the production of cold.

Reasons for participating in the competition(s)
En 3 semaines de travaux sans gêne au bon fonctionnement du magasin, l’hypermarché Géant Casino de Valence Sud a ainsi enregistré jusqu’à 36°C de moins pendant les pics de chaleur sur la toiture après application du CoolRoof, une diminution de 12 % sur la facture énergétique globale en été.
L'hypermarché a donc réalisé une économie d'énergie et donc de carbone grâce à la diminution de consommation en climatisation. Le confort intérieur et extérieur du bâtiment est également amélioré puisque le bâtiment ne souffre plus des fortes chaleurs, la température intérieure ressentie est réduite et l'effet d'îlot de chaleur tout autour du bâtiment est également maîtrisé.
