The initial step was to identify the necessary actions and develop a plan for enabling remediation work by local contractors.
Where it was verified that mechanical and electrical functionality was correct, the control logic was checked to ensure it matched the needs of the space. Other steps followed to optimise the controls as time allowed, however the focus was on returning as many systems as possible to a stable, automatic operation. The process for identification and remediation of issues was broadly as follows:
BMS optimisation was achieved via the following:
EECO2 developed the Quality Risk Assessment documentation and worked with the client Quality team to gain approval
Fixing defective mechanical equipment and sensor issues – routine maintenance activity following existing SOP’s
Changing filters and fan belts where required – routine maintenance activity following existing SOP’s
Checking software logic and compliance with original specification and current site requirements
Modifying software logic as required to deliver a more optimised control strategy
EECO2 also monitored system stability and performance pre and post project implementation.
Energy savings identified (per year)
Energy cost savings identified (per year)
Emissions reduction (per year)
The project defined 3 primary success criteria which were deemed to have been met:
• Improved temperature and humidity control
• Reduced energy consumption
• Improved HVAC system compliance and robustness.
In addition, as the project was delivered while both sites were working live it was imperative that conditions were maintained within quality compliance limits at all times. This objective was met with zero quality compliance environmental excursions.
