Sector: Restaurant
Location: Manchester, England
Size: 125 m²
Status: Completed Q4 2022
InnoDez UK delivered a focused MEP engineering and energy upgrade for a 125 m² casual dining unit inside Manchester Arndale. The team produced coordinated Mechanical, Electrical and Plumbing design and engineering that supports a visible cookline, fast table turns, and comfortable dining conditions, while meeting the landlord’s odour and noise criteria and keeping services visually discreet.
Provide robust kitchen extract with multi stage abatement. Maintain steady temperatures at the shopfront without draughts. Keep background noise low beside neighbouring fashion tenants and circulation routes. Use simple controls that staff can operate day to day. Reduce electricity use versus the outgoing fit out and hand over with sub metering so the operator can track baseload and after hours drift.
Mechanical: Heat pump VRF with heat recovery. Dedicated outdoor air unit with energy recovery and CO₂ based demand control sized to peak occupancy. Low velocity linear slots along the dining edge to avoid cold spills, returns through concealed shadow gap grilles. Tempered make up air to the cookline to hold a slight negative pressure locally.
Kitchen extract and odour control: Canopy extract with acoustic lining, electrostatic precipitation, UV treatment and deep bed carbon polishing in a lined riser. Discharge via the landlord riser to roof in line with centre standards.
Plumbing: New hot and cold services, backflow protection to risk category, floor gullies in wet zones, condensate routing to trapped points. Underslung grease interceptor sized to British guidance with clear maintenance access.
Electrical: New distribution board with spare capacity and sub metering for HVAC, lighting and kitchen small power. Dedicated clean circuits for combi ovens, fryers and refrigeration. Surge protection and RCDs to BS 7671.
Controls and energy: Three simple modes set on handover. Trading, clean down, closed. Night setback on temperature and ventilation. Trend points for CO₂ and temperature so managers can verify conditions and tune schedules.
Services were routed only through designated landlord risers. Ceiling depth on the shop floor was preserved by keeping the main DOAS run in back of house and using slimline slots. Sprinkler head moves were coordinated to the new lighting layout, with concealed heads where permitted by the landlord. Fire alarm and public address interfaces were listed on an interface schedule issued to centre management and Building Control. Acoustic targets at the lease line were met with correctly sized attenuators, short flexible connectors and lined ductwork.
Designed and documented to UK regulations and centre 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. Odour and noise limits were evidenced with supplier certifications and third octave attenuation calculations.
Verified odour control at the lease line during a live lunch service.
Even temperatures in the dining area with low background noise next to the mall.
Reduced energy use compared with the legacy fit out using heat recovery, demand controlled ventilation, LED lighting and sub metering led tuning.
Clear O&M, a one page user guide and a seasonal checklist for the operator.
