Getting energy-efficient design into school construction can be tough, but the Gen7 modular-classroom building from American Modular Systems, Manteca, Calif., fits many of the latest energy-efficiency advances into one package, bringing the cutting edge of green technologies to modular school construction.

Introduced at the Green California Schools Summit 2009 in Pasadena, Calif., in December, Gen7 is being touted as a “grid-neutral” modular-classroom solution for California school districts.
