Project Description

How do you build one of the largest homes in Boulder County (at 13,000 sf) and achieve a HERS score of zero—with a swimming pool and spa?

To take advantage of mountain views, large western facing glazing was to be used. In order to maintain space comfort and counter the potential overheating of the radiant floor system, the owners requested the implementation of radiant cooling technologies. With these unique challenges, the design team felt a specialized mechanical engineer was needed.

DMA Engineering contracted to provide energy modeling, system analysis, system design, and advanced modeling using Computational Fluid Dynamics Modeling (CFDM) of the radiant cooling system.

The entire mechanical system was designed by DMA and included four fan-coil units, 25+ radiant zones, 18T of ground source heat pump water-to-water units coupled with energy recovery units, and a state-of-the-art control system.

DMA also participated in the commissioning of the system to ensure it was working as designed.
