Chicago-based contractor Emcor Services Team Mechanical recently installed the HVAC system and solar wall at a Grainger’s 1 million square-foot distribution center.
The 2,700-square-foot wall pre-heats the outside air before
it comes in contact with the rooftop HVAC unit serving two storage rooms. The
air is regulated through dampers tied into a building automation system, which
switches from pre-heated to ambient air based on temperatures.
Emcor also performed all of the
project’s commissioning work. They expect the facility to qualify for a gold
rating under the Leadership in Energy and Environmental Design building
“Our client has calculated that the solar wall will pay for
itself in less than 10 years,” said Emcor division President Robert Doessel.
