Reducing the interior temperature of a building has become a strategic priority in bioclimatic architecture and sustainable design.
In hot climates, especially in urban areas, passive solutions are sought to improve thermal comfort without increasing energy consumption, as this is now a technical and environmental requirement.
In this scenario, reflective technology has gained prominence as an efficient, cost-effective and easy-to-implement tool. Among the available solutions, Tecnotop 2C White is positioned as an avant-garde reference. It is a high-performance two-component acrylic finish that achieves a solar reflectance index (SRI) of 105, an exceptional value that places it above most of the coatings available on the market.
WHAT IS SRI AND WHY DOES THE VALUE OF 105 MATTER?
The Solar Reflectance Index (SRI) is a standardized metric that combines two physical properties of a surface:
1.Solar reflectance: the ability to reflect incident solar radiation.
2.Thermal emissivity: the ability to release absorbed heat.
The SRI scale ranges from 0 (corresponding to a standard black surface that absorbs almost all radiation) to 100 (an ideal white surface). In practice, however, some advanced products can exceed 100 thanks to formulations that combine very high reflectance and emissivity.
An SRI of 105 means that Tecnotop 2C White not only reflects the majority of solar radiation (visible and infrared), but also effectively emits the absorbed heat, significantly reducing heat build-up on surfaces exposed to the sun. This results in less heat transmission into the building and, therefore, a significant reduction in energy consumption for cooling.
The use of reflective coatings such as Tecnotop 2C White contributes directly to:
- Decrease the energy footprint of the building.
- Meeting environmental certification requirements such as LEED®, BREEAM® or municipal energy efficiency programs.
- Reducing the urban heat island effect by limiting thermal accumulation on exposed surfaces.
REAL SOLUTIONS - SUCCESSFUL RESULTS
Tecnotop 2C White has been successfully implemented in multiple projects that sought to improve the thermal performance of roofs and facades without resorting to complex structural interventions. Some notable cases are the Al Wukai logistics center in Doha, Qatar.
Tecnotop 2C White is not just a cladding, it is an intelligent thermal control tool. With an SRI of 105, this solution combines technology, efficiency and simplicity in a single technical gesture. In the architecture of the present - and especially of the future - cooling without consuming will be one of the greatest challenges. And these types of passive systems will be at the heart of the answer.
