The Pearce Building is a multi-let commercial property in Maidenhead. As one of the sites included in the award-winning LSH project for Nuveen (formerly TH Real Estate), 4D Monitoring was originally brought in to monitor the central plant.
However, we quickly identified the existence of secondary systems that were providing air conditioning to the tenant demise.
These additional systems were not centrally controlled, which meant analysing the central plant wouldn’t provide visibility of performance.
To capture performance data from secondary air conditioning units, our environment profiling solution was utilised. Smart mini sensors were deployed across the tenant demise to provide live temperature and air quality readings.
With sensors in place, our system diagnosed run time errors, which meant systems were operating out of line with office occupancy hours.
We also identified secondary air conditioning systems operating 24/7 on unoccupied floors, leading to significant energy wastage.
Equipped with the data we provided, the site management team at Pearce Building was able to collaborate with tenants to optimise run times. Air conditioning supply to unoccupied spaces was also switched off.
This has had a significant impact on energy spend. Within the first three months, LSH had documented a 9.5% kWh saving, which equates to £4,500.00 or 15 tonne CO2e emission reduction over the first three months.
