Project
Site & Plant
Campus with mixed property portfolio including listed buildings, >50 properties including teaching, concert hall, catering sports and accommodation. Range of plant including: BMS systems, HVAC, GSHP, PV, Solar thermal, refrigeration.
Objectives
Reduce energy use & spend across portfolio, specifically Cedars Hall (newly built). Reduce CO2 – a major student concern. Fulfill ESOS energy reporting obligations and assess potential for electrification of transport & maintenance fleet.
Challenges
A lack of energy data in high cost buildings & age, listing & diversity of property portfolio.
GRIDIMP SERVICES
Installation of impHub into existing BMS systems, real time energy data to our cloud services/dashboards. Also, impHubs automate DSR control of HVAC systems in response to peak pricing. Completion of ESOS reporting. Defining and assisting in student & staff energy engagement program to promote positive change.
The Benefits
Visibility of energy data by asset type: Dashboards on energy use & cost allowed for:
Automated load shifting:
Fully automated control of HVAC through the impHub, ensuring minimal use during peak charging periods, reducing energy costs & gaining DSR revenue.
Metering Corrections:
Identified incorrect meter scaling, corrections allowed for accurate reporting & analysis.
£10k refund from bill reconciliation:
Data highlighted inaccuracy in billing, resulting in supplier refund.
System Optimisation:
Identified incorrect meter scaling, corrections allowed for accurate reporting & analysis.20 % Saving on Heat Pump running costs: Achieved by controlling run times.
Investment Planning:
Analysis to support investment decisions including: EV charging, electrification of transport fleet, heating systems maintenance and lighting replacement programme.
Reduced Co2 Emissions:
Lower energy consumption during peak demand, reducing reliance on carbon intensive peaking plant. Energy procurement from renewable/low carbon suppliers.
£40,000 saving on energy procurement:
Analysis to support investment decisions including: EV charging, electrification of transport fleet, heating systems maintenance and lighting replacement programme. Greater knowledge of energy usage allowed gridImp to assist in the procurement of a new
energy supplier.
