Sector: Administrative office
Location: Canary Wharf, London, England
Size: 140 m²
Status: Completed Q1 2025
InnoDez UK delivered a fast-track MEP engineering and energy upgrade for a 140 m² admin office on a multi-tenant floor at One Canada Square. The team produced coordinated Mechanical, Electrical and Plumbing design and engineering that preserves ceiling height, improves comfort, and reduces electricity use without impacting neighbouring tenants or the base-building systems.
Provide even temperatures across open-plan desks and small meeting rooms, low background noise, and glare-controlled lighting suited to screen work. Avoid visible grilles at the façade, connect only to landlord risers, and hand over simple controls plus sub-metering so facilities can track baseload, after-hours use, and seasonal changes.
Mechanical: Heat-pump VRF with heat-recovery; outdoor air via DOAS with energy-recovery and CO₂-based demand control; low-velocity linear slots at the perimeter to prevent draughts, returns via shadow-gap grilles.
Electrical: New distribution board with spare ways and sub-metering for HVAC, lighting, and small power; workstation power on clean radial circuits; surge protection and RCDs to BS 7671.
Lighting: High-efficacy LED scheme with UGR-controlled downlights for general light, adjustable accents for collaboration zones, and daylight-linked dimming at the façade.
Plumbing: Local tea-point with point-of-use water heater, compliant backflow protection, and condensate routing to trapped gully.
Controls & energy: Three modes (working / clean-down / closed), night setback, occupancy and time-schedule logic to trim ventilation and lighting after hours.
Services were routed to designated landlord risers only. Ceiling depth was protected by keeping the main DOAS branch in back-of-house and using slimline slots on the floor. Fire alarm and emergency lighting interfaces were set out on an interface schedule for Building Control and the estate team. Acoustic targets for open-plan and meeting rooms were achieved with lined ductwork, flexible connectors, and correctly sized attenuators.
Designed and documented to UK regulations and typical tower standards, including Part L (energy), Part F (ventilation), Part B (fire), Part M (access), BS 7671 (electrical), BS 5839 (fire detection), and BS 5266 (emergency lighting). Air and lighting criteria align with CIBSE guidance for offices.
Stable indoor conditions with low background noise and no perimeter draughts.
Colour-consistent, glare-controlled lighting for VDT work, with scenes for focus and collaboration.
Reduced electricity use vs. the legacy fit-out through heat-recovery, demand-controlled ventilation, daylight dimming, and metering-led tuning.
Clear O&M, one-page user guide, and a seasonal checklist for facilities.
