There is a feeling that building is very expensive, without having the guarantee of the quality of the result. It is not because of the lack of commitment of the professionals involved, but because of a low efficiency in the organization of work.
Where is the efficiency of a building?
- In its construction
- In its use
- In its maintenance
Efficiency in construction:
To improve it, we must introduce manufacturing concepts, both in terms of organization and quality control and work performance management. We must transform the construction process of the work in a process of assembly. The objective is to guarantee quality and comfort by reducing costs in order to offer a more adjusted price.
Efficiency in its use:
We have to make buildings with low energy demand with the aim of reducing consumption, through high levels of insulation and air tightness. Our buildings consume a third of energy than those of the same characteristics in traditional construction.
Efficiency in its maintenance:
All the operations of repair, modification, substitution and expansion must be agile both at the level of the construction elements and the facilities.
All the facilities (drains, water, electricity, air conditioning and ventilation) pass through a 120-cm-high basement that occupies the entire building. By having a direct access from the outside all these operations are carried out without entering the habitable zone.
We have designed a specific and open computer program that centralizes in a single screen the management of all facilities , both existing and those that may be incorporated in the future. This screen gives us information about the operation and consumption of the different installations and allows their manipulation from any device, even remote (mobile phone). It is connected to a fault center, from where small problems can be solved or find the necessary repair.
How do we get it?
With a new integral constructive system that incorporates a new way of understanding the envelope of the space, the incorporation of the concept of assembly on site, maximizing the work in the workshop and a centralized management of all the facilities.
The why of the form:
If the skin of a building is where we lose (winter) or win (summer) energy. If we keep in mind that the roof and edges are the points of maximum energy loss, the cylindrical shape allows us to reduce these critical points by covering the maximum volume of air with the minimum surface of skin. There is more volume of indoor air with the same useful surface. We gain depth in the work planes and storage areas (between 20 and 30 cm in tables, bedside tables, shelves, kitchen countertops and cabinets). All this gives a great feeling of spaciousness and comfort.
