CHALLENGE Modern (completed 2007) dedicated office complex comprising over 18 floors, sub-let to multiple tenants. Each floor has been provided to the tenant as a full functional core & shell, with several floors having undergone recent refurbishments, two floors still undergoing fit-outs. HVAC services are common to all floors and fall within Landlord operation and maintenance, however significant amount of tenant supplemental cooling plant to critical environment space. Lighting in communal areas falls within Landlord demise and direct control.‘New site’ with little life-expired plant requiring upgrading, however, site appears to be performing poorly compared to benchmark therefore focus shifts to operational control re-commissioning exercise. Assessment requires identification of the potential HVAC & building services’ energy savings of the offices by conducting a detailed energy assessment of the facility, compiling the relevant utility data to determine overall energy utilization, identifying equipment deficiencies through analyzing mechanical and electrical systems, sequences and operating schedules.
SOLUTION Detailed site assessment (2-4 days per site depending on size and complexity) + pre/post analysis & report generation. No-Cost Projects include: waste water abatement & available capacity release procurement exercises, BMS Time schedule adjustments - ALL HVAC plant affected, early-morning ramp-up reduction, lighting time schedule adjustments, winter comfort cooling requirements. Identification of Low-Cost Projects & measures requiring further investigation: Re-commissioning Pro-logik Lighting Central Control System, Car Park Lighting Dimming + PIR Solution, Dry-cycling Optimisation, Tenant Engagement Initiative - AMR + aM&T Programme, BMS & Head-end Lighting Control Interactivity & onsite staff training capabilities.
RESULTS 1,433,200 kWh energy savings identified (9.7%), 459 tonnes of carbon savings identified (9.9%), £165k operational cost savings identified (14.3%)
