The editorial team
Editorial reviewers
Every calculator, chart, and guide on WhatSize Appliance is reviewed by a named researcher with a specific domain focus. We don't cite "the editorial team" generically — we cite the person, the standard, and the section.

A note on framing. "Research lead" and "standards methodology editor" are honest titles for published-research roles — not trade certifications. We don't claim EPA 608, NATE, or state licenses anywhere on this site. Our reviewers are researchers who follow public industry standards (AHAM, DOE, ACCA, NEC, ASPE) and verify their work against manufacturer spec sheets.
