The heating and air conditioning in the new wing of the Denver Museum of Nature & Science will run on an unusual, subterranean heat source: the recycled wastewater rushing through the pipes below.
The museum could have proposed a standard ground-source heat pump system, one that taps into geothermal sources by drilling and installing numerous shallow wells over a large area, to provide a heat and cooling resource for the units. But instead, they’re planning to install an open-loop system that uses water circulating within the city’s municipal water system.
“That’s the unique piece about it,” says Dave Noel, vice president of operations and chief technology officer for the museum. “A traditional ground source heat field might cost two-thirds of the total costs of the whole system. In this case, if we can make this work, not only are the costs much cheaper, but we won’t require as much space.”
