The affairs additionally helps architecture owners install and use those products.
Trane accomplished UC Davis acceptance for the Voyager DC, a amalgam rooftop air conditioner that uses indirect, evaporative cooling to access cooling accommodation and abate aiguille electrical demand.

The added winner, in 2009, was Coolerado Corp. of Denver, Colo.
