Contractor Mag: California?s first LEED Gold winery proves ideal application for radiant cooling

The plans for one of Napa Valley?s most prestigious wineries, called for an in-floor Uponor radiant heating and cooling system to precisely control temperatures in two vital production areas: a state-of-the-art, 20,000-sq.ft. winery and a 26,931-sq.ft. barrel cellar. Reid?s concern was that plans specified the radiant tubing be installed at the bottom of the 20-in.-thick concrete slab, instead of sandwiched in-between.

?For most commercial applications, we position the tubing in the top third or middle to ensure a comfortable heat transfer,? said the 33-year plumbing industry veteran and owner of San Rafael, Calif.-based <a title="Reid Heating &amp; Energy Inc." href="http://www.reidheatingandenergy.com/">Reid Heating &amp; Energy Inc.</a> ?Initially, I was leery about placing the tubing on the bottom of the slab, but I discovered that this lower position made the slab more efficient for this particular application.? 


















Indeed, the radiant system did perform as planned, and the project?s environmentally friendly construction recently received LEED Gold certification. That recognition made Hall St. Helena the first winery in California to achieve the Gold certification from the U.S. Green Building Council.
