What This Standard Covers
- Sub-metering architecture for whole-home, circuit-group, and individual load monitoring
- Current transformer selection criteria by circuit ampacity and monitoring resolution required
- Communication bus topology from energy monitoring hardware to central controller
- Demand management relay placement and control wiring for high-load circuits
- Battery backup and generator integration points within the energy management system
- Data export protocol and API integration requirements for home automation platforms
Who It Is For
- Electrical contractors installing energy monitoring hardware on Restrepo-spec projects
- AV and automation integrators configuring energy management dashboards
- Architects and MEP engineers coordinating energy infrastructure in construction documents
- Facilities managers overseeing energy performance on large residential and commercial properties
When To Use It
- During electrical design to incorporate monitoring hardware in panel schedules
- At pre-construction meetings to align electrical and low-voltage trades on data conduit runs
- Before panel cover installation to verify all CTs and communication wiring are in place
- At system commissioning to validate data accuracy against known load profiles

Field Notes
Energy management is a systems problem, not a hardware problem. The monitoring equipment is only as useful as the infrastructure it sits on. This standard defines that infrastructure: the panel space, the CT positions, the communication conduit, and the integration data points.
We wrote this standard because the conversations about energy monitoring typically happen too late. By the time the homeowner asks about real-time usage data, the panels are closed and the conduit runs are buried. Getting the infrastructure right at rough-in costs far less than adding it after the fact.
