Lighting controlled by use and presence.
S4 designs and integrates lighting control for buildings, offices and commercial spaces: scenes, schedules, occupancy and daylight sensors, with on-off, phase-cut, 0-10 V, DALI and KNX, and integration with the BMS, to improve comfort and cut energy use.

Who it is for
4 layers, from field to operation. Choose a profile to see which part of the system concerns you.
Infrastructure manager
Lower consumption and control from a single point.
Contractor or developer
A building that meets RETILAP and adds to LEED or EDGE.
Commercial space manager
Scenes by time and by use with no manual intervention.
Lights on where nobody is.
Whole floors lit at night, empty rooms at full brightness and fixtures at 100% next to windows with plenty of daylight. Consumption rises and comfort does not improve.
You need it if you recognize any of these signs:
- Lights stay on outside working hours.
- Brightness cannot be adjusted by zone or by task.
- Lighting systems in different areas do not talk to each other.
- A certification such as LEED or EDGE is the goal and the lighting has no control.
- Changing a schedule means calling a technician.
How the system is built.
We use open protocols: DALI (IEC 62386) to dim each luminaire and read its status, and KNX to integrate lighting, blinds and HVAC. For the BMS, BACnet or Modbus.
Field
- Dimmable LED luminaires
- Occupancy and daylight sensors
- Keypads and scene panels
Control
- Drivers and modules: on-off, phase-cut, 0-10 V or DALI
- DALI or KNX bus
- Zone controllers
Platform
- Scene and schedule programming
- BMS integration
- Home automation: blinds, security and entertainment
Operation
- Adjustments from an app or screen
- Usage reports
- Maintenance
What is included and what is not.
Included in the service
- Survey of luminaires, circuits and the use of each space
- Lighting calculation, zones, scenes and sensor strategy
- Protocol selection based on the installation and operations
- Supply and installation of LED luminaires, drivers, sensors and controllers
- Lighting for commercial, public and sports spaces
- Programming, BMS and home automation integration, testing and training
Out of scope
- Major electrical works and main switchboards, coordinated with the electrical contractor
- Managing the LEED or EDGE certification process: we provide the lighting documentation
- Decorative or architectural lighting design
Anything out of scope is coordinated with the right party or quoted separately, and is always stated in writing before we start.
How we do it, step by step.
-
Assessment
Walk-through of the spaces, inventory of luminaires and circuits, and a record of actual schedules and uses.
DeliverableCondition and opportunities report
-
Design
Lighting calculation, zones, scenes, sensors and protocol, with expected consumption against current.
DeliverableTechnical report and control design
-
Integration
Installation of luminaires, drivers and sensors, scene programming and BMS integration.
DeliverableInstalled and programmed system
-
Commissioning
Level measurements, sensor and scene tuning, and training for users and maintenance staff.
DeliverableTest and measurement report
-
Operation and improvement
Adjustments for changes of use, maintenance and consumption tracking.
DeliverableConsumption and status reports
Reference regulations and standards.
These are the usual references for this type of system. The technical report of each project identifies which ones apply, depending on the use, size and location of the installation.
Regulatory reference, indicative
- RETILAP
- Colombian technical regulation for lighting and public street lighting: illuminance levels by task and product requirements.
- IEC 62386 (DALI)
- Digital lighting control protocol, addressable per luminaire.
- KNX (ISO/IEC 14543-3)
- Open standard for home and building automation.
- LEED and EDGE
- Green building certifications; lighting control contributes to their energy efficiency requirements.
- RETIE
- Colombian technical regulation for electrical installations: governs the service connections and circuits that power the equipment.
What stays in your hands.
Lighting calculation
Levels by space and by task.
Technical report
Zones, scenes, sensors and protocol.
Documented programming
Scenes and schedules by zone.
Measurement report
Levels measured after tuning.
Certification documentation
What LEED or EDGE requires on lighting.
How we apply it in your sector.
What people ask us most.
What savings can be achieved?
It depends on the starting installation and on use. The assessment estimates it from site data and measurement in operation confirms it.
Can it be done in existing buildings?
Yes, zone by zone. Some sensors and controllers avoid rewiring everything.
What is the difference between DALI and 0-10 V?
With 0-10 V, a group of luminaires is dimmed in an analog way. DALI is digital: it addresses each luminaire, allows grouping by software and reports faults, with more flexibility when the layout changes.
Does it help to obtain LEED or EDGE?
Yes. Lighting control contributes to the energy efficiency requirements of those certifications, and we deliver the technical documentation the process asks for.
Do you do home automation?
Yes. The same system can control lighting, blinds, security and entertainment in homes and high-end spaces.
