Electrical Installations in Singular Buildings


Today, we find a range of electrical and mechanical installations in all buildings that take into consideration the whole requirement of the activities to be carried out inside the building itself. However, in the past this was not always the case, either because the need for buildings to be fitted out was very low, or because the technology needed to carry out this task was not available.

Fitting out a building for it to be inhabited largely depends on two very different infrastructures: electrical and mechanical installations.
The electrical installations  found in buildings are relatively modern and have only been in use, as we know them today, since the middle of the twentieth century. These serve the purpose of distributing electricity from the building’s electric connection right to the very last lightbulb or socket.  Generally speaking, with regard to a building’s electric installations, the following arrangement of components is found:

  • Transformer station: can be either inside or outside the building and reduces the line voltage to what we know as low voltage via different input cells, the  general protection and measuring board and outflow to a transformer.
  • General protection and measuring board: protects the installation for possible network failures or short circuits.
  • Individual spur lines : distribute electricity from the general board to the secondary boards, which in turn, serve to protect each specific part of the building.
  • Emergency systems: refer to an accompanying power line to the general one which is intended to ensure the supply in the event of a failure. Hospitals or hotels are kinds of singular buildings which require these systems. One such solution is that of backup generating equipment.
  • Outputs from the switchboard: make up the final wiring canalization of the system before the electricity is received and can flow through tubes, underground, on plates or embedded in the exterior walls of the building.So far, we have gone over all the equipment that supplies electricity to the whole building when all wired together, but does this all take place continuously? Does it have some sort of mechanism to manage operations?

    ” The sustainability of an electrical installation hinges on its automation as well as the ability to adapt to the building’s power demand.

    The sustainability of an electrical installation hinges on its automation as well as the ability to adapt to the building’s power demand. This is achieved by implementing inmotics (integral management of non-residential buildings) in each system which also has a dual role: energy efficiency and savings.

    In order to achieve greater energy efficiency,the demand for continuous energy needs to be monitored, a demand which is interrupted at intervals by the operation of certain equipment that cause excessive energy consumption. Take for instance, a commercial building in which illumination accounts for up to 40% of the electricity consumed. The use of control systems not only reduces the size of the invoice amount for this service, but also the amount of CO2 emissions and therefore, its effects on climate change.

    ” The need for automating a singular building’s electrical installations calls for managing the electrical systems remotely via a web platform.

    In keeping with the need to automate the electrical installations, and with regard to the development of the information society, managing the electrical systems remotely via a web platform is called for. The advantages this presents are numerous as it moves the supervisory position and enables data dumping to be outsourced, while at the same time providing further information with a better response speed and therefore facilitating its parameterization.

    The integral management of the power system is not conceived without its counterpart in buildings, namely: the whole mechanical systems, which are crucial towards providing the building with climatic comfort. This will be discussed in a future blog in The Energy of Change.
