Become a popular solution for residential and commercial buildings, it helps reduce the consumption ofenergy and reduce urban heat islands. This practice isinspired by traditional methods, such as in the Cyclades, where the roofs and facades of white have been used for centuries to freshen up the home.
The principle of the cool roofing is to reflect a very large part of the solar rays that arrive on the roof. Reflective materials are used in cool roofing has an albedo (reflection coefficient) higher than the conventional materials. Thealbedo is a measure of the reflection of sunlight on an area. The lower thealbedo is high, the surface is reflective.
The cool roofing is a technique aimed at reducing the amount of heat absorbed by the roof ofa building by using coatings, reflective covering the roof of the white.
This reduces the surface temperature of the roof and severely restrict the flow of heat to theinterior of the building. This technique can be implemented from various materials and can lead to a reduction of the consumption ofenergy for air-conditioning and a level of thermal comfort is higher.
The security on the roof requires the strict observance of the rules of working at height and theproper equipment of teams, including PPE, in order to prevent accidents.
Annual maintenance is recommended to maintain theeffectiveness of the cool roofing and Cool Roof develops a robot cleaner using therain water in order to limit the consumption of this precious resource.
The cool roofing is not suitable for all types of roofs. A minimum slope of 1% to 2% is recommended to avoid the retention ofwater and areas of flash.
Theapplication of paints, reflective roofs on historic requires theapproval of the Architects of the Buildings of France and of the commons, but this method is increasingly accepted, even in heritage areas.
Our Office of Thermal Study has conducted a technical analysis on the link between the cool roofing and winter. In winter, the solution CoolRoof continues to reflect the light of the sun, which can reduce theabsorption de chaleur solaire et augmenter les besoins en chauffage.
Cependant, cette propriété peut également prolonger la présence de neige sur les toits, offrant ainsi une isolation naturelle qui réduit les pertes de chaleur.
It is crucial to consider the local climate : in regions with severe winters, this additional insulation can be beneficial. However, as with any project, an in-depth study conducted by our Office of Technical Studies, will ensure the relevance and effectiveness of our solutions.
An urban heat island is an urban area is significantly warmer than the vegetated areas in the surrounding area – an increase that can reach 12°C to metropolises like Paris !
This phenomenon ICU is increasingly studied and its impacts the health and social care are considered by many specialists as a “disaster silent” : the rise of mortality, health problem and dehydration frail…
The concept of the “kettle heat” to characterize homes inappropriate has become an important issue for planners.
Heat waves affecting the most vulnerable. Cool Roof is to reduce theimpact of urban heat islands with sustainable solutions and inclusive.
Neighborhoods economically precarious are the most affected by the heat island, making their mitigation an issue of social justice, environmental and health.
Fight against heat islands requires to combine solutions green, grey and soft, without the use of air conditioning, for optimal impact.
The cool roofing contributes to improving the environmental quality of buildings and cities, and to achieve the sustainable development goals.
Cool Roof improves the environmental performance of buildings and cities, while supporting the goals of sustainable development.
By reducing the warming of the buildings, a Cool Roof reduces theuse of air conditioning, and helps prevent the gas emissions of HFCS, which are very harmful to the climate.
By limiting the warming of buildings, our solution CoolRoof is an alternative to air-conditioning systems, energy-intensive and polluting making use of gas HFC.
Our solutions Cool Roof enhance your commitments to ESG focus on three areas : environmental (reducing GHG emissions), economic (lower energy bills), and social (to improve the comfort of users). In addition, our FDES formalize your approach décarbonation.
Today,today, Cool Roof continues toinnovate by offering products that are designed to maximize the thermal performance while reducing theenvironmental impact. Thanks to the formulations, eco-design andintegration of bio-sourced materials such as shells ofoysters, our solutions meet the requirements ofan ecological transition successful.
