Manage and sub-bill WAGES* in large commercial buildings (* Water, Air, Gas, Electricity, Steam)
“I want to make sure I get the most out of my HVAC and lighting control systems. I also need reliable consumption data to sub-bill my tenants’ utility use.”
Solution in brief
Meter key energy points to acquire consumption data and identify abnormal use patterns
Solution applicable to all commercial buildings greater than 5,000 square meters
Each tenant’s utility use is sub-metered, and the resulting consumption files can be downloaded via a standard web browser for use with an invoicing application.
Ethernet-based architectures are particularly suitable for commercial buildings where IT network connections are generally already available. The solution is built around an iRio RTU (Remote Terminal Unit) at main switchboard level and Twido PLCs distributed at secondary or final switchboard level.
Metering is provided through power meters using pulsing contacts or Modbus Serial Line communication and flow meters using pulsing contact, Modbus Serial Line communication, or M-Bus open metering communication.
The system ensures data acquisition, processing, and transmission, including database generation, dashboards, curves, and reports. Electric metering can be provided by a number of meter options
