this goal, cutting-edge technologies are being installed in both parts of the
building - beginning with the ground underneath it. Before the foundations were
poured, 200 wells were dug 300 feet deep for geothermal heating and cooling.
Water will be continuously circulated through these wells, with the temperature
differences tapped to provide heat in the winter and cooler air in the summer.
circulate within the building through radiant heating and cooling panels in the
ceilings above employee workstations. Looking like small radiators behind
stainless steel screens, these allow the warm and cool air to be concentrated
where workers spend their time, not in hallways or other underused areas.
