| Radiant floor system before the concrete pour. |
Last week the second of two concrete pours covered the final section of radiant floor system at CSHQA's new offices at 2nd & Broad and marked a major milestone in this 5-month construction project. Crews started at 6:30 am and by 10:30 the initial pour was nearly complete (to be followed by many hours of detailed finish work.)
The yellow, lego-like substrate of interlocking panels provides built-in spacing and fastening for the PEX tubing, plus insulation for heating and cooling functions. The system extends throughout the entire office except for a few spaces such as walls and the entryway foyer. Nearly 5 miles of PEX were covered by approximately 2-7/8 inches of concrete.
Once connected to Boise's geothermal system the radiant system will provide low-cost heating; in warm months cold water will be pumped through for cooling. This comfortable, energy efficient system completely replaces convential furnace and forced-air systems and the operational savings are expected to be significant. –

Pre-cut sub-structure boards are used as guides for an even pour.
