Moor House, designed by Sir Norman Foster and located in the heart of London’s financial district, is one of the largest office buildings in the city. Managed by Moor House Management Services (MHMS) on behalf of Deka Immobilien, the building required a sustainable lighting solution to align with its environmental goals.
Skanska commissioned GCL to replace existing AR111 capsule lamps in the building’s entrance lobby. This high-profile upgrade focused on energy efficiency, improved safety, and seamless architectural integration.
The upgrade aimed to:
Lower long-term energy costs
Reduce the building’s carbon footprint
Preserve the consistent colour rendering needed to highlight interior artworks
Additionally, the new lighting needed to match the modern aesthetic of Moor House, which frequently exhibits art in the lobby area. The installation had to be completed safely and efficiently, often during off-peak hours, without disrupting occupants.
The lighting refurbishment posed several logistical and technical challenges:
The 9-metre-high ceiling created access and safety concerns
Disruption had to be kept to a minimum for staff and visitors
Work needed to coordinate with art installations and scheduled events
Lighting design had to complement both architectural and artistic elements
To overcome these challenges, GCL developed a bespoke approach. Key elements included:
Sourcing and manufacturing LED luminaires tailored to existing fittings
Scheduling work during nights and weekends to reduce disruption
Conducting a detailed risk assessment before installation
Coordinating closely with contractors and MHMS throughout the project
The end result was a solution that met both visual and environmental requirements, while improving safety and reducing maintenance overhead.
The project delivered a wide range of advantages:
Reduced energy load from 40kW to just 4.9kW
Maintenance-free operation using long-life LED luminaires
Reduced environmental impact aligned with CRC efficiency targets
Efficient project delivery, completed ahead of schedule
No noticeable change in colour rendering despite the lighting change
Seamless cooperation between GCL, Skanska, and MHMS
