By applying our cool roofing solution to the roof of a shopping centre located in zone H3, the building reduced its internal heat peaks by 7.3°C and achieved energy savings of up to 21.5 kWh/m²/year.
Like many commercial buildings in hot regions, this shopping centre suffered from severe overheating during the summer months. Despite the use of large-scale air-conditioning systems, temperatures regularly exceeded comfort levels, resulting in :
A significant increase in discomfort degree hours (over 1,000 °C.h per month),
Persistent over-consumption of energy,
Reduced thermal comfort for employees and customers.
The Cool Roof thermo-reflective coating was applied to the entire roof of the site, covering several thousand m², without interrupting activity. The aim of the operation was to :
Reduce the surface temperature of the roof,
Limit heat transmission to the interior,
To relieve cooling systems, particularly during peak periods of sunshine.
Maximum drop observed: -7.3°C in indoor ambient temperature,
Average daytime gain : -3,8 °C,
Visible and immediate reduction in daily temperature fluctuations.
In September, the number of uncomfortable degree hours fell from 1,096 °C.h to just 80 °C.h,
This gain contributes directly to better quality of service and greater protection for sales staff.
Depending on the thermal resistance of the building, electrical energy savings vary between 9 and 21.5 kWh/m²/year,
Cool Roof remains effective even on roofs that are already insulated,
An estimated carbon footprint reduction of 29.2 kgCO₂/m² over 20 years.
Financial savings of up to €4,467/year, with no additional maintenance,
ROI estimated at 5.7 years,
An operation with a high energy, environmental and social impact, carried out without any structural modifications to the building.
Some of our feedback, like this one, is voluntarily anonymised at the request of our customers. This approach is designed to respect the confidentiality of sensitive or strategic sites, while sharing the concrete results achieved thanks to our cool roofing solution.
