Colón Towers in Madrid sets new standards with NZEB, WELL and LEED certifications
TRILUX has completed a landmark lighting project at Colón Towers (Torres Colón) in Madrid – now recognised as Spain’s most sustainable office building. Owned by insurance group Mutua Madrileña, the 31-storey building is the first in the country to achieve certification as a Nearly Zero Energy Building (NZEB) and will also receive WELL and LEED certifications in recognition of its outstanding environmental and workplace credentials.
An integral part of meeting these ambitious standards was the smart, energy-efficient lighting solution designed and delivered by TRILUX Spain. Around 3,000 luminaires were installed throughout the building, offering not only optimal light quality and visual comfort, but also integrated intelligence and digital control.
High-performance lighting for modern workspaces
TRILUX developed bespoke linear luminaires specifically for this project, all equipped with integrated presence and daylight sensors. The luminaires adjust automatically to the time of day and occupancy, supporting both energy efficiency and user wellbeing.
Lighting colour temperature (4,200 Kelvin), high colour rendering (CRI 90), and a unified glare rating of 19 ensure compliance with WELL certification criteria, helping to promote productivity and comfort. For added design value, Sonnos pendant luminaires in black were also selected to enhance aesthetics in key areas.
Smart, connected and future-proof
Lighting throughout the building is controlled using the Casambi system, with each floor connected to a central gateway. This enables the building team to manage lighting remotely, monitor performance in real time, and streamline maintenance. If a luminaire needs replacing, reprogramming is not required – delivering both time and cost savings.
This project underlines TRILUX’s capability in delivering cutting-edge lighting solutions that meet the highest sustainability and workplace standards, supporting building owners and occupiers alike.

Located within The University of Edinburgh’s College of Medicine and Veterinary Medicine, the Usher Institute aims to transform health in society by working with people, populations, and data. The Usher Building houses the Usher Institute with its four core research centres and the Edinburgh Clinical Trials Unit – alongside partners from public, private and third sector organisations. Funded as part of the Data-Driven Innovation Initiative of the Edinburgh and Southeast Scotland City Region Deal, the facility has been designed by international design practice Hassell Studio to be a welcoming space for focus, collaboration, and engagement, with space for around 1000 occupants
Delivered by Leon Gray, a TRILUX distributor, and installed by EMTEC Group with lighting design by Ainsley Cramer, the lighting scheme consisted of 400 custom-designed Sonnos downlights featuring a bronze and black RAL finish; these downlights blended perfectly with the building’s architectural metal finishes. Over 600 Solvan Flows, 300 Amatris, and numerous LED linear runs were installed, providing uniform and efficient lighting throughout the facility.
