Energy monitoring

“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.”

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
depending on your distribution architecture and metering performance requirements:

• Masterpact or Compact NSX built-in power meter
• PM9C/200/700 communicating power meters
• Cost-effective EN40/PM9P/ME4zr pulsing power meters

> 10% energy savings through usage analysis

• Even greater savings if additional controls are implemented

> Lower energy consumption through load scheduling, conditioning, and shedding

> Reliable industrial RTU technology ensures information is available

> Cost-effective

• The solution works with low-cost pulse metering technology
• Possible low-cost initial rollout to secure quick ROI; can be scaled up later with additional metering
• iRio pre-developed software modules minimize software development costs
• Uses existing IT infrastructure (Ethernet TCP IP)

> Web based for easy implementation; no dedicated WAGES workstation required

> Ready-to-use data fi les facilitate sub-billing

+ Low software development costs: iRio comes with pre-developed software modules
+ Powerful customization capabilities: implement additional control functions if and when required
+ Highly scalable for maximum cost-effectiveness
+ Uses existing IT infrastructure (Ethernet TCP IP): no need to install new communication bus
+ Less time spent on-site: remote alarm and operation
