Awards:

APEX Engineering received the 2006 Sustainability and Energy Efficiency Leadership Award for work on the 2002 Bush Brothers Beans Employee and Office Facility Addition; completed in 2004. This project used an innovative approach to reclaim waste heat from the baked bean processing line to heat the entire new complex when process work was on-going, as well as heat sidewalks and patios. Snow melting on sidewalks and patios saved ice melting chemicals, which would have been used for clearing snow, as well as providing a safer walking surface for employees and visitors. This system also increased process production by reducing heat build-up in the process which had been problematic for the nationwide manufacturer of baked bean products and other canned vegetables.
