Edinburgh Quay 1

Client challenge

The building needed its inefficient fluorescent lighting replaced to cut operating cost and carbon, but a straight compliant swap would have committed the client to a higher capital figure than the outcome justified. The brief therefore included a commercial challenge as well as a technical one.

Delivery

Installed in phases across an occupied building, working alongside the building's management team to keep access, egress and fire strategy intact throughout.

Greentech approach

• 01

  The specification was challenged before order, not simply priced, to find equivalent performance at lower capital cost.

• 02

  Tenant disruption was treated as the governing constraint, so the programme was built around occupied floors.

Engineering scope

• Complete strip-out of legacy lighting across multiple floors, communal areas and stairwells.
• LED replacement throughout.
• Daylight harvesting on perimeter zones.
• Presence detection in meeting rooms and corridors.
• Architectural scene setting in the atrium.

Outcomes

• Reduced capital cost

  Achieved through the change in luminaire specification.

• Lower energy load

  A substantial reduction in lighting electricity use from removing fluorescent and adding controls.

• Less routine maintenance

  Long-life LED replaced short-life fluorescent tubes for the facilities team.
