CBRE Hallmark Building: Condition Based Maintenance

London, EC3M 7DQ

Project Details

Due to changes in Building Occupancy, the landlords of this Central London Property had been looking at savings that can be achieved from changing the SFG-20 maintenance programme.

We recently completed the trial Installation of our Condition based Fan Coil Maintenance sensors on behalf of contractor CBRE at the above site using our Lorawan IOT hardware which was rapidly installed to monitor the filter condition of the Fan Coils throughout the site.

Reduced occupancy in every building has meant a change to std PPM maintenance needs, and with M&E equipment being used less often meant CBRE could offer substantial savings vs the SFG-20 standard.

The objective for CBRE and the landlords was to enable a move away from the SFG-20 regime which dictates the frequency of fan coil maintenance. By monitoring the filter condition of 10% of the total number using rapidly installed IoT differential pressure sensors, enables CBRE to undertake Fan Coil filter cleans only when needed.

Unlike other systems, the EnviroLogik system is unique in that its systems can communicate and penetrate through concrete/steel floors and plant room walls and provide remote monitoring and critical alarming data using a secure Mobile network, enabling monitoring of key items, especially when the site has less occupants.

Special IOT Sensors were quickly and easily installed by EnvioLogik technicians to monitor the Fan Coils, but other sensors will be added at a later date and could include:

  • Chiller Refrigerant Pressures/Leaks
  • Chiller & Pump Energy Consumption
  • Plant Room Water Leaks from Heating and Chilled Water Pumps and Sump Pumps
  • Water Tank Temperatures
  • AHU Filter differential pressures
  • Boiler and Chiller Flow Temperatures
  • Water Leaks from Toilets and Sinks
  • Indoor Air Quality including CO2, CO, NO, VOC’s Lux, Humidity Temperature and Occupancy Control

Instant alarms and alerts are notified to the site management and maintenance team by Email to mobile devices and through a web based dashboard.

Decisions can then be made to fix items before they fail, thereby offering true Condition based Maintenance.

These IOT sensors, and secure Gateways are not connected to a Wi-Fi, or Buildings ethernet network making them highly secure, and can expand into monitoring many other systems.

The customer is now able to make savings without affecting occupant comfort by staying ahead of problems.
