Real-time equipment and meter data improve campus operations

An India-based commercial and residential real estate developer aims to lead in modern, sustainable workspaces. At a three-tower, 1.6 million-square-foot office campus, its facilities teams needed clearer insight into equipment performance and a faster way to validate tenant energy billing. The developer deployed OpenBlue Equipment Performance Plus and OpenBlue Net Zero Plus with the Tenant Billing module. Real-time equipment and meter data helped the team identify operational faults, optimize air-side operations and automate meter reading. The work identified more than 170,000 kWh in annual savings and created the potential to reduce monthly billing verification from up to 40 hours to approximately two.

Impact Highlights

More than 170,000 kWh in annual savings identified

Monthly billing workload reduced from up to 40 hours to approximately two

106 tenant meters can report with 99.5% accuracy

Limited visibility and manual billing slowed facilities teams

The developer’s office campus includes three towers and a range of connected equipment and meters. Facilities teams had little visibility into equipment performance or the areas that required maintenance. Multiple operational faults were present, including simultaneous heating and cooling, improper valve modulation, pumps running at high speed and sensor abnormalities.

Tenant billing also required significant manual effort. Teams spent up to 40 hours each month verifying and validating billing data in spreadsheets. With 150 energy BTU meters across the campus, the process required a more efficient way to read meters, analyze consumption and identify anomalies.

The developer needed reliable operational data to address equipment inefficiencies while maintaining indoor air quality and tenant comfort. It also needed a more accurate, automated approach to tenant energy billing that could reduce repetitive work for the facilities team.

Connected data supports equipment optimization and automated billing

The developer implemented OpenBlue Equipment Performance Plus to bring together real-time information from control systems, meters, weather forecasts and utility rates. The platform used these inputs to highlight operating conditions, identify faults and support actions to minimize costs and improve efficiency.

Using the resulting insights, the facilities team optimized air-side operations. Actions included resetting CO₂ levels, improving valve control and resetting temperature parameters. The work also addressed chiller and pump inefficiencies and corrected operating conditions that affected comfort and system stability.

For tenant billing, the developer deployed OpenBlue Net Zero Plus with the Tenant Billing module. The module automated meter reading, analyzed energy consumption and identified anomalies. This replaced a process in which facilities teams manually checked and validated tenant billing information in spreadsheets each month.

Together, the two OpenBlue solutions gave the team a more direct view of equipment and energy data across the campus. The approach supported both operational improvements and more accurate reporting from 106 tenant meters, while allowing the developer to balance indoor air quality with tenant comfort.

Data-led improvements identify energy savings and reduce billing effort

The deployment identified more than 170,000 kWh in annual savings. Optimized air-side operations reduced the cooling load, saving energy and costs for the landlord and tenants. Correcting CO₂ levels and addressing chiller and pump inefficiencies also improved comfort and system stability while achieving an optimal balance of indoor air quality and tenant comfort.

Billing automation created the potential to reduce the facilities team’s monthly workload from up to 40 hours to approximately two hours. The Tenant Billing module automated meter reading, analyzed consumption and identified anomalies, reducing reliance on manual spreadsheet checks.

The campus can now use 106 tenant meters that report with 99.5% accuracy. By combining equipment performance insights with automated energy data, the developer gained clearer visibility into operating faults and areas requiring attention. The outcomes provide a factual basis for ongoing efficiency improvements across the three-tower office campus.
