Industry Solutions
A step-by-step guide for MEP engineers on writing Division 26 and Division 25 specifications that meet IECC 2021 and 2024 end-use submetering requirements.
Industry Solutions
Designing a compliant monitoring system for mixed-use buildings using Panoramic Power wireless sensors, Leviton BCMs, and the PowerRadar unified front end.
Sustainability & Compliance
The 2024 IECC's Section C405.13.7 requires end-use submetering for every significant non-electrical load: boilers, chillers, furnaces, water heaters.
Technology & Innovation
Self-powered wireless sensors, cellular connectivity, and clamp-on BTU meters solve every retrofit installation challenge in occupied commercial buildings.
Energy Intelligence
Subcircuit monitoring turns retro-commissioning from a periodic consulting engagement into continuous optimization, typically worth 15-20% of spend.
Sustainability & Compliance
The 2024 IECC lowered the monitoring threshold from 25,000 to 10,000 sq ft, more than tripling the buildings required to install end-use metering.
ROI & Business Case
Transparent equipment-by-equipment pricing for IECC-compliant energy monitoring across three building archetypes—25,000, 50,000, and 100,000 sq ft.
Technology & Innovation
Why behind-the-meter BESS needs subcircuit metering to capture 80-95% of theoretical demand reduction and prove grid-service revenue to the utility.
