Active Architecture and Environmental Sustainability
The building envelope as an urban lung: beyond energy efficiency.
The construction sector is responsible for 40% of global energy consumption and 30% of CO2 emissions. At VM Group, we are responding to this climate emergency by transforming the building envelope from a passive barrier to a bioactive surface capable of interacting with the environment and purifying the air.
Photoactive Ventilated Facades: Bioactive Technology
A sintered surface for the health of people and the city.
Photoactive facade technology is based on the integration of titanium dioxide (TiO2) onto the ceramic surface through a sintering process at extremely high temperatures. This treatment is not a simple surface coating, but a permanent molecular transformation that activates photocatalysis.
Exposed to sunlight, the surface produces active oxygen, triggering a natural reaction that neutralizes air pollutants, inhibits the growth of bacteria and mold, and decomposes dirt particles.
-
Certified Durability: Titanium dioxide acts as a catalyst and is not consumed by the reaction. Accelerated aging tests guarantee the system's effectiveness for over 50 years, maintaining its bioactive performance throughout the building's life cycle.
-
Asset Enhancement: The adoption of next-generation materials not only meets ethical criteria but also significantly increases the property's market value, aligning it with the highest international sustainable construction standards.
Digital Engineering: Laser Scanner Surveying
"Precision is the foundation of sustainability. There can be no efficiency without an exact mapping of reality."
Every VM Group project is preceded by a 3D laser scanner survey.
This technology allows us to map the existing structure with millimeter tolerances, generating a very high-density "point cloud."
This digital foundation is essential for the design of photoactive facades, as it ensures that each module is manufactured and installed with such precision as to optimize exposure to light and, consequently, maximize the performance of the photocatalytic process.
