Seville City Council has awarded Eiffage Energía Sistemas one of the three lots in the contract to fully refurbish the outdoor lighting across the “Sevilla TechPark” technology park, in a deal worth over €3 million. By swapping 635 light points for LED technology with point-to-point remote management, the works will modernise the installation and cut the area’s electricity consumption by more than 77 per cent.
An infrastructure legacy from Expo ’92
Much of the lighting at Sevilla TechPark (formerly the Cartuja Science and Technology Park) was originally designed for the 1992 World Expo. Conceived as a temporary solution to meet the needs of a six-month event, the installation has now been in service for more than three decades.
The preliminary technical report found marked deterioration, brought on by age and a lack of upgrading. On the 12-metre lighting columns, inspectors identified damaged covers, detachment at the anchorages and clear signs of corrosion, defects that also affect the 4-metre pedestrian columns. Wear on this scale put both the network’s service life and the safety of the installation at risk.
On the energy side, the park runs on high-pressure sodium vapour discharge luminaires. Some pedestrian areas still rely on conical units with diffusers that throw light into the upper hemisphere. With no dimming or time scheduling in place, consumption stayed flat all night long, regardless of actual traffic on each road.
Scope and key features of the works
The project calls for a comprehensive overhaul that brings together luminaires, columns and advanced control systems. In Sector 2, Eiffage Energía Sistemas will work on 635 light points. Once the layout has been reorganised to correct poor lighting uniformity on carriageways and footways, that number will rise to 661.
Annual consumption will fall from 462,533 kWh to 105,316 kWh. That saving of 357,217 kWh a year means a reduction of 77.23 per cent, the highest of the three lots put out to tender.
The new LED luminaires we are installing incorporate advanced technical solutions:
- Colour temperature of 2,700 K, warmer and gentler on the night-time environment.
- Zhaga connector, so sensors that measure environmental parameters can be added without replacing the luminaire.
- Dimmable drivers integrated into a radio-frequency remote management system.
- Zero installed upward light ratio (ULR), so no light escapes towards the sky.
- Aluminium housings finished in the site’s signature blue
- LED floodlights at uncontrolled pedestrian crossings: dedicated units delivering 40 lux of vertical illuminance (class CE2), with anti-glare optical control (G2 towards vehicles and G3 towards pedestrians).
Point-to-point remote management and monitoring
We will move the control cabinets out of the transformer substations and fit them with centralised remote management, giving remote control over switch-on and switch-off and real-time monitoring of electrical parameters.
Every luminaire will also have its own point-to-point remote management. Lighting levels can then be tuned to the time of night, the type of road and how each space is actually used
With this project, we at Eiffage Energía Sistemas consolidate our urban modernisation model: energy-efficient, digitalised infrastructure that respects the heritage and identity of its surroundings
