UMS Sub-Metering

The Utility Monitoring System (UMS), a utility management tool for individual facilities, has new sub-metering capabilities that are beginning to be widely implemented. The UMS can provide tenant sub-metering for cost allocation, device sub-metering for operations tracking and performance monitoring, and end-use sub-metering (laundries, restaurants, etc.) for cost control and energy conservation monitoring.

The latest version of the UMS data acquisition server can accept sensor inputs in any of the industry standard formats: digital pulse, analog voltage (0-10 V), current (4-20 MA), and resistance (100-100k Ohms). It also has a serial port for Modbus RS-485 communications that can support up to 32 external devices such as single and multi-channel electric meters, electrical branch circuit meters, digital and analog multi-channel sensor expansion modules and any Modbus-based meter. The data acquisition server also accepts wireless data transmission through a RS-485 based radio frequency receiver and has cellular modem capability.

Sub-Metering and Sustainability

According to the Environmental Protection Agency, buildings currently account for 39% of U.S. primary energy consumption, 70% of U.S. electricity consumption, and use 12.2% of all potable water (15 trillion gallons). To promote sustainability the U.S. Green Buildings Council has developed the LEED (Leadership in Energy and Environmental Design) Green Building Rating System. The average LEED certified building uses 32% less electricity, 26% less natural gas and 36% less total energy than a conventional building.

Sub-metering can help you acquire advanced LEED certification by contributing directly toward points under several LEED green building certification categories:

  • Monitoring & Verification - Baseline Building
  • Monitoring & Verification - Tenant Sub-metering
  • Building Operations & Maintenance
  • Performance Measurement - Enhanced Metering
  • Documenting Sustainable Building Cost
  • Water Efficiency

UMS Sub-Metering Capability Highlights

  • Virtually unlimited sub-metering capability Supports up to 32 Modbus devices, each of which could be multi-channel, such as an 8 channel tenant electric sub-metering system.
  • 8 channel on-board user selectable sensor inputs for basic gas, water, thermal and electric meter inputs or environmental sensors such as temperature, relative humidity, rainfall or carbon dioxide measurements.
  • 8 channel RS-485 pulse and analog sensor input expansion modules with similar capabilities as above.
  • 8 channel Modbus multi-circuit electric meters. Stand-alone Modbus networked power meters.
  • RS-485 wireless communication.
  • Communicate with any type of stand-alone Modbus meter.
  • Cellular Modem Capability

Sub-Metering Value Summary

As facilities move to obtain LEED Certification, the UMS will be an indispensable tool for utility tracking and identifying energy savings opportunities. The investment in sub-metering will be quickly repaid through cost recovery and efficiency improvements.
