“Probably the most sustainable concrete
structure in the world “
Structural Concrete Magazine- March 2014

“Holedeck is an outstanding structural solution for concrete slabs, technically efficient and flexible, and architecturally singular and attractive.”
Alejandro Bernabeu, Director Bernabeu Engineers, Professor at the Architectural School (UPM)

Due to the way that HOLEDECK slabs are designed, the system eliminates the concrete mass that is not working to support shear, thus, and the overall weight of the structure without compromising its ability to achieve long spans. This results in an optimization of the built volume and concrete consumption, and thus minimizes the carbon footprint of a building project.

Holedeck can increase health security against pandemics such as COVID-19. Sick Building Syndrome (SEE) thus Sick Building Syndrome (SBS) is the name given to the set of diverse symptoms that are not generally accompanied by any organic lesion or physical sign that individuals present in affected buildings, individuals, present in affected buildings.

In practice sick buildings are a part of buildings that present problems: its occupants present complaints regarding their health in a higher proportion than it would be reasonable to expect (>20%) and the causes are difficult to identify since in many cases they have a multifactorial origin.

45 millions of Americans suffer symptoms associated with SEE / SBS. According to the EPA (Environmental Protection Agency, U.S.A.) the indoor air becomes 6 a 10 times more polluted than the outside. Given this reality, it seems necessary to improve Indoor Air Quality Control to detect cases of inadequate ventilation (physical parameters), as well as the presence of chemical pollutants from inside or outside the building (chemical parameters), from biological contaminants in the air circulating through the ventilation system (microbiological parameters).

Biological contaminants in many cases come from bio-aerosols (airborne particles, made up of living things, or substances that have been released by a living being) against whose presence we can only act by eliminating contaminated materials and therefore the source of internal amplification and dissemination. "Studies in Europe suggest that SBS is associated with mechanical ventilation systems that use humidifiers and refrigerants. Specifically, the area of ​​surfaces with fleecy materials, wallpapered surfaces, and the allergenic amount and proportion of soil dust have been linked to the incidence of disorders. The origin of poor indoor air quality may be different for different buildings, sometimes being the ventilation system itself."

Dirt encourages the growth of aerobes and fungi, this being the cause of more than 37% of sick leave and the ailments caused by the so-called Sick Building Syndrome (allergies, Headaches, eye and ear irritations, respiratory problems, pneumonia, etc)

The ills associated with Sick Building Syndrome are especially worrisome in the case of hospitals and health centers, where the joint and constant presence of patients (immuno-depressed in many cases) and visitors from abroad aggravates the large number of Nosocomial infections (acquired inside the health center) and respiratory ailments. It is contradictory to find spaces that are difficult to access and accumulate dirt in places that require maximum hygiene and asepsis.
