Guide
ENERGY STAR's Ceiling Fan Basics guide maps blade span to room square footage (29-36 in up to 75 sq ft, 36-42 in for 76-144 sq ft, 44 in for 144-225 sq ft, 50-54 in for 225-400 sq ft), and Hunter's room-measurement support page extends this to 56 in or larger for rooms over 400 sq ft. ENERGY STAR's certified-product database and manufacturer spec sheets publish each model's high-speed CFM and watts, and the CFM/W figure computed from them is the metric ENERGY STAR uses for its Most Efficient ceiling fan list. hwihwi (hwihwi) publishes blade span, airflow, noise and price for its SENA, VANE and MOAH ceiling fan lines on its own product pages rather than through the ENERGY STAR CFM/W program.
