Lead Methodology Editor
Ewan Holcomb
Lead methodology editor at HeatPumpScore. Owns the scoring formula, the worked examples, and every calibration change to the rubric.
Ewan leads the methodology desk at HeatPumpScore. His background is mechanical engineering — heat-transfer fundamentals, residential HVAC system design, and building-envelope basics — and he spent years writing technical explainers about heat pumps, cold-climate performance, and electrification economics before joining HeatPumpScore to build the scoring formula behind every zip-code verdict on this site.
He is an engineer-turned-editor, not a licensed HVAC contractor. He owns no installer business and accepts no manufacturer affiliations. His job is to make sure every claim published on HeatPumpScore stays inside the fence of US government and federally-funded references (EIA Open Data for fuel prices, NOAA 1991–2020 Climate Normals for HDD/CDD/winter design temperatures, DOE Building America for performance curves, DSIRE for rebates, ENERGY STAR / NEEP for certified cold-climate models) and that every calibration change to the formula is documented before it ships.
Ewan writes the methodology page, the worked Minneapolis example, the persona guides, and the editorial principles. He reviews every per-zip and per-state page generated by the content pipeline against the scoring rubric, and he signs off on news articles before they go live.
