Shipments have been made to Andoain (Guipuzcoa), Villanueva de los Infantes (Real city), Bilbao, Aranjuez, Cabanillas del Campo (Guadalajara), Ourense, Terrace (Barcelona), Castellbell and Vilar (Barcelona), Cuenca, Girona, Real Village (Castellón), El Palmar (Murcia), Aviles (Asturias), Real city, Úbeda (Jaen), Manzanares (Real city), Alfambra (Teruel), Zamora y multitud de localidades de Toledo (through Toledo Civil Protection).

In Madrid and surroundings they have reached the Getafe Hospital, Hospital Fundación Instituto San José, El Escorial Hospital, Virgin of Health of Toledo, Princess Hospital, Santiago Rusiñol de Aranjuez residence, Sanitas la Zarzuela Hospital, Moncloa HLA Hospital, Buenos Aires health center, Tajo de Aranjuez Hospital, Nuevo Belén Hospital, Alcorcon Foundation University Hospital, Mostoles Hospital, The House of the Physio, Anna Residence, Infanta Elena Hospital, Ramón y Cajal Hospital, Ocaña Penitentiary Center, several residences of Ocaña (Thank you! Jose Miguel Sanchez), Villanueva de los Infantes medical center and residence, University Dental Clinic Alfonso X el Sabio University, Valdemoro Hospital, Psychiatric Hospital of Leganés, Alcorcón Residence, Madrid VII Prison Center…. and many more.

Civil Protection of Madrid has distributed 18.000 protective visors; they arrived at the IFEMA Hospital when they needed it most, and many nursing homes in Madrid.

Artenea3D, has received 3600 masks that he has assembled and delivered to dozens of hospitals and medical centers.

From 2020, the energy consumption of buildings will be nearly zero (NZEB). But do we know how to achieve it?

Holedeck and Uponor have developed HOLEDECK ACTIVE BASIC an innovative thermally-activated concrete slab, result of the research project carried out with the participation of ¨Holedeck¨, the ¨Spanish Institute of Cement and its applications¨ and ¨Eduardo Torroja Institute of Building Sciences¨.

This Holedeck lightweight slab is already the most efficient solution of the market in relation to material consumption, minimizing the environmental impact. In addition, the use of perforations for the passage of facilities currently reduces the height required on the ground of non-residential building and promoting the possibility of having an additional plant for every x plants built. The design of the HOLEDECK ACTIVE BASIC slab allows integrating systems and elements specifically designed for standard modular ceilings, as well as geometries and adapt to conventional modulations.

In addition, this slab can thermally activate by the integrating system Uponor TABS (Thermal Active Building System). By a framework of integrated circuits into the slab, water runs into the structure previously heated or cooled by any source of renewable energy (geothermal, aerothermal, solar…) to modify the temperature of the concrete slabs and use its inertia. This way, the slabs contribute to cooling and heating the environment in a healthy way, silent, without air drafts and according to the needs and comfort of air conditioning required at all times.

HOLEDECK ACTIVE BASIC contributes to the achievements of buildings NZEB and European targets of Circular economy. Running costs are reduced by more than 30% regarding existing buildings, and energy consumption by up to 60%.

Structures that must resist seismic loads have to be designed and conceived under this premise from the very beginning of the process. This fact is so relevant that can (and should) affect in a general way the selection of the structural system.

In general, every seismic-resistant building consists of three types of elements:

Since installations have become a fundamental aspect of projects, with a significant presence in the overall budget, and volume of the building, designers have tried to integrate them as much as possible with the building, making them coincide with other architectural elements such as structure and envelope.

Welcome. From HOLEDECK we are convinced of the structure’s relevance in sustainability. We believe that future structures should have the smallest direct and indirect impact on the carbon footprint, should be flexible, and allow for versatility which translates in greater possibilities of configuration and uses, which can contribute actively and/or passively in the construction of nearly zero-energy buildings (nZEB). That is our commitment.
