B.I.G. Enterprises, Inc., of South El Monte, California, created custom, energy-compliant guard booths for a California university. The new designs meet energy-efficiency standards in California as well as in Washington state, which has the strictest standards in the United States. The booths also comply with ADA access requirements, have high-output HVAC systems, and include restrooms. The exteriors incorporate design features that complement the surrounding architecture. The factory-built, prefabricated booths are easy to install and long-lasting.
