Butt Glass Window Energy Efficiency

Hi, we are in the process of building a home and we have a wall that currently shows a 24' window. The builder said he planned on that being butted glass. I'm trying to figure out how energy inefficient that is versus using store-front glass for a space that wide. Any help on figuring this out would be greatly appreciated.
