Sector: Clinic
Location: Liverpool, England
Size: 110 m²
Status: Completed Q4 2023
InnoDez UK delivered a concise Mechanical, Electrical and Plumbing design and engineering package with targeted energy upgrades for a new optometry clinic inside Liverpool ONE. The brief required quiet rooms, stable temperature and humidity for diagnostic equipment, and compliant ventilation without visible façade grilles. The scheme was coordinated to landlord rules and handed over with simple controls the practice team can operate without technical support.
Create calm testing rooms with low background noise, maintain close control of indoor conditions for OCT and retinal imaging, and keep odour and cross contamination risk low between rooms. Provide clean electrical supplies for sensitive kit, future cable capacity, and metering so the operator can track baseload and after-hours drift.
Mechanical: High-efficiency heat-pump VRF with heat recovery. Fresh air via DOAS with energy recovery and CO₂-based demand control. Pressure regime from reception to clean rooms to prevent transfer. Low-velocity linear slots in patient areas to avoid draughts.
Plumbing: Hot and cold water to hand-wash basins and lab sinks. Point-of-use heater for rapid hot water. Backflow protection to risk category. Condensate routing to trapped gullies.
Electrical: New distribution board with spare ways and sub-metering for HVAC, lighting and clinical sockets. Dedicated circuits and clean earth for imaging equipment. Surge protection and RCDs to BS 7671. Structured cabling routes for devices and future adds.
Controls and energy: Three simple modes, open, clean-down, closed. Night setback on temperature and ventilation. Trend points for CO₂ and temperature so the manager can verify conditions.
Services were routed to landlord risers only. Fire alarm, emergency lighting and PA interface points were scheduled for Building Control and the centre management team. Ceiling depths were preserved by keeping the main DOAS run in back-of-house and using concealed grilles at front-of-house. Acoustic targets for consultation rooms were met with lined ductwork, flexible connectors and properly selected attenuators.
Designed and documented to UK regulations and typical landlord 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. Pressure regime and fresh-air rates follow relevant healthcare guidance for small outpatient settings.
Even temperatures and low background noise in testing rooms.
Verified pressure regime between rooms and reception.
Reduced energy use versus the legacy fit-out through heat recovery and demand-controlled ventilation.
Clear O&M, one-page user guide and a seasonal checklist for staff.
