Energy codes moving specification from appearance to measurement
Solar heat gain limits in most developed energy codes have tightened past what body tint alone can deliver, which forces specification onto measured performance rather than onto a sample held up to the light. Coated products grow at 7.2% wherever that comparison actually happens. Where codes remain loose, appearance still decides and darker glass keeps winning arguments it should lose on physics. Regulation is doing the selling that data alone never managed. Suppliers presenting energy model output rather than sample boards reach the argument on ground they win. Regulation is doing what data could not.
