Two live EPA documents give different carbon factors for New York City — an 11% gap. EPA has published no eGRID2024 and no 2026 EF Hub, and third parties are filling the vacuum. Here is which figure to use and how to label it.

In New York City the DEP owns, maintains and reads the service meter. The owner gets a bill, not a data asset. Here is the arithmetic on what an unseen leak costs — and why we won't quote you a savings percentage.

NYC's LL97 electricity coefficient halves in 2030. The gas coefficient does not move. Per MMBtu saved, the ranking inverts — and the gas channel the energy code already requires is the one the 2030 problem needs.

A 2026 state-by-state tracker of IECC and ASHRAE 90.1 adoption, with the specific submetering trigger for every U.S. jurisdiction.
Technology & Innovation
How clamp-on ultrasonic water meters work, which pipes they fit, what accuracy to expect, how to install them correctly, and what they cost.
Technology & Innovation
How clamp-on ultrasonic transit-time meters measure compressed air flow, why Doppler fails on clean gas, and the installation and signal checks that make readings trustworthy.
Technology & Innovation
Compare electric submeters across eight capability tiers - accuracy, integration, labor and warranty - so you buy the right meter instead of the biggest one.
Energy Intelligence
Follow one submeter reading through OptimizeOS, from raw signal to a clean number, a benchmarked baseline, an alert, and a decision an operator can act on.
Technology & Innovation
How landlords and property managers turn raw submeter readings into defensible tenant invoices with OptimizeOS, no spreadsheets or manual reconciliation.
Technology & Innovation
See how OptimizeOS fault detection turns continuous submeter and sensor data into routed, escalated alerts so technicians fix faults before a breakdown.
ROI & Business Case
Demand charges can be 30 to 70 percent of a commercial electric bill. See how OptimizeOS makes peak demand visible in real time so your team can cut it.
Energy Intelligence
See how OptimizeOS reads utility bills with AI vision, verifies every parse, and reconciles billed usage against submeter data to catch overcharges.
