COMMERCIAL FACILITIES
Electrical installations in commercial premises must comply with the Low Voltage Electrotechnical Regulations. It is mandatory that the project be drawn up and signed by a competent technician and that there be a project manager during the execution of the work.
Once completed, a certificate of completion and an official installation certificate must be issued.
In addition, the installer must provide a manual with technical information on the installation, including single-line diagrams, wiring plans, location of panels, devices, light points and power sockets, as well as the layout of the earthing network.
This manual must also contain instructions for use, safety and maintenance to ensure the correct and safe operation of the installation.
INDUSTRIAL FACILITIES
The scope of work for industrial electrical installations begins with the construction of the electrical connection, which can be medium, high or low voltage. In industrial electrical installations, all power, lighting and special system circuits in both new constructions and renovations are the responsibility of the industrial electrical contractor.
Renovation of Industrial Electrical Installations
When additional capacity is required in existing industrial buildings that need to be expanded, industrial electrical installations require a load analysis to rationally meet the growing requirements of this new equipment through modifications to the substation or motor generator sets.
Within this speciality, we carry out the installation and maintenance of industrial electrical installations and electrical equipment used in an industrial plant or building. The distinctive component of an industrial electrical installation is the electrical substation, as electricity suppliers commonly supply large consumers in this way at medium and high voltage.

ICT TELECOMMUNICATIONS
What is an ‘ICT Installation’?
These are the installations necessary to capture, adapt and distribute terrestrial and satellite TV and radio signals, as well as basic telephone and broadband telecommunications services, to homes and premises.
Royal Decree Law 1/1998 establishes that authorisation will not be granted for the construction of new buildings or for the comprehensive renovation of existing ones if the building project is not accompanied by an ICT Technical Project. The project must be signed by a telecommunications engineer or technical telecommunications engineer.
Residential or office buildings constructed prior to Royal Decree Law 1/1998 must have this infrastructure, provided that the number of individual or collective TV antennas installed exceeds one third of the dwellings or premises in the building or when decided by the community of owners in accordance with the provisions of the Horizontal Property Law.
HOME AUTOMATION AND CCTV SECURITY
1. Energy saving
Some examples of energy management applications include:
• Switching equipment on and off based on presence or on a timer
• Zone-based temperature control
• Switching off heating in areas where windows are open
• Controlling appliances on night-time rates
• Automatically switching off various resources that are not in use
• Monitoring the use of the building’s energy resources
2. Comfort
Comfort consists of improving the quality of life of the building’s occupants.
Examples of applications for these installations include:
• Use of wireless control (remote control)
• Regulation of environmental conditions by zone
• Automation of irrigation, based on the climate detected by the system
• Automatic activation by presence, remote control, etc.
• Use of information and management panels
• Possibility of easy reprogramming according to changing needs
• Special attention to elderly or disabled people
3. Safety (people & property)
Safety consists of preventing domestic risks and accidents. In this section, a distinction is made between the safety of property and the safety of people.
Personal safety:
• Automatic lighting in high-risk areas (stairs, etc.)
• Deactivation of electrical sockets (small children, etc.)
• Telephone alerts
• Option to connect to alarm receiving centres
• Gas or water leak detectors that shut off valves to the home in the event of a leak
• Health alarm (e.g. sends a signal to a hospital in case of emergency)
Property security:
• Intrusion detection
– Volumetric sensors (detect movement)
– Hyperfrequency sensors (detect the sound of breaking glass)
– Magnetic sensors (detect the opening of doors and windows)
– Video recording of the intruder
Technical alarms:
• Fire detection
• Gas or water leak detection
• Power failure
Presence simulation:
• Operation of certain devices
• Random switching on of lighting sources
Remote notification:
• Issuing a telephone notification in the event of an alarm
• Notification via the internet
Communication:
Ensure and establish communications within the home and with the outside world.
The possibilities within this pillar are:
• Internal communication systems
• External communication systems
• Communication systems with the outside world
• Connection to service providers, e.g. TV, etc.
TECHNICAL AND SPORTS LIGHTING
In sports facilities, it is very important to reduce maintenance costs, as they involve a continuous demand for both water and energy. With the help of the latest technological innovations in efficiency, these maintenance and conservation costs can be reduced.
Lighting is an area that accounts for high electricity consumption in technical, school or sports facilities, depending on their size, their main use and the climate of the area where they are located. This consumption can be around 15%.
That is why any energy-saving measures in lighting will have a significant impact on costs.
It is estimated that reductions of between 20% and 85% in electricity consumption for lighting could be achieved through the use of more efficient components, control systems and the integration of natural light.
Sports facilities have large roof areas that allow for the generation of photovoltaic electricity and its subsequent injection into the general distribution network or use in the facilities themselves for lighting.
When designing the lighting for a sports facility, it is necessary to take into account the area to be calculated and the values adopted in this calculation by the indicators EHE_HEH, EVE_VEV, U1U_1U1, U2U_2U2, GRG_RGR, RaR_aRa, etc.
In the calculation area, a grid is organised that is distributed regularly and symmetrically over the entire pitch, field or playing field. The number of grid points (net knots) must be at least 14 x 21 for fields with minimum dimensions (65 x 105 metres), or a maximum of 15 x 22 for fields with maximum dimensions (75 x 110 metres).
- The lighting levels required in sports facilities depend on the type of activity taking place; the following classification has therefore been established:
- Stadiums and multi-purpose sports grounds: 200 to 500 lux.
- Tennis courts: 150 to 500 lux.
- Outdoor swimming pools: 100 to 300 lux.
- Pelota courts: 300 to 500 lux.
- Training courts: 100 to 200 lux.
- Competition football stadiums with fewer than 5,000 spectators: 100 to 200 lux.
- Competition football stadiums with 5,000 to 15,000 spectators: 300 to 400 lux.
- Competition football stadiums with more than 15,000 spectators: more than 600 lux.
- Colour TV broadcasts: 1,400 lux. (For matches broadcast on colour TV, lighting values above 1,000 lux are required).
PLUMBING AND DHW
The design of the domestic hot water (DHW) distribution system varies depending on the type of building. The highest consumption occurs in hotels (24% of total energy consumption), followed by hospitals (17%) and sports or educational centres (less than 15%). In homes, DHW is as essential as cold water, while in offices, shops and large retail outlets, consumption is lower.
Trends and regulations:
- Mandatory use of solar thermal energy according to the Technical Building Code (CTE).
- Periodic inspections of boilers >15 years old according to RITE.
- Compliance with energy labelling on DHW heaters and storage tanks.
Good practices for efficiency:
- Regular boiler inspections (annual).
- Regulate the outlet temperature to 45ºC and insulate pipes and tanks to reduce losses (>10%).
- Detect leaks and overconsumption through inspections.
- Install thermostatic valves and water-saving devices (aerators).
- Minimise the distance between DHW production and consumption.
- Use pumps with frequency converters and programmable timers to save electricity.
- Take advantage of residual heat and opt for low-temperature condensing boilers.
- Solar energy can cover between 50% and 70% of DHW demand.
- Heaters without pilot lights prevent constant gas consumption.
Services offered:
- Plumbing, DHW, supply and sanitation installations.
- Distribution networks and pressure groups.
