the challenge
Bringing controls and data insights to an older building via a BMS upgrade can surface many previously unknown issues. As this data is so heavily relied upon for defect and tuning decisions, it is critical to validate the data coming in prior to making any changes. Changes based on erroneous data can result in poor outcomes despite a BMS upgrade, therefore data validation is critical.
The solution
Replace the shopping centre BMS and connect a data analytics platform, allowing greater control and observations of the site and key energy users.
The data feeding into the analytic platform was validated, and point-to-point tested prior to acting on any defect and tuning opportunities.
The results
The quality of the data resulted in well-informed decision making and significant improvements to the building performance. Stakeholders were pleased with the final outcomes, and the key statistics speak for themselves.
- Project payback 1.35 years
- 19% reduction in annual electricity consumption.
- +0.5 Star NABERS increase
