Project Profile: MacRostie Winery & Vineyards

20150209MacRostie-Winery014-edit

Pastoral vistas are almost a prerequisite for a winery, as are unique entertainment spaces where customer comfort is key. At MacRostie Winery & Vineyards (MacRostie), Healdsburg, California, Luke Higgins, director of operations, wanted “an environment of casual sophistication.” The selected HVAC system had to contribute to that environment.

“They also wanted a very open feel to the project,” said Sean Froom, PE, LEED AP, project manager, TEP Engineering, Santa Rosa, California. As the engineer on the project, Froom worked to have a clean, open aesthetic, which meant, “ceilings as high as possible with no exposed ductwork.”

For such an interior space, especially in a building where the options for system location were limited, our system was an excellent solution. Higgins said, “The facility is not ideal for HVAC with so much indoor-outdoor flowing space. So a multi-zone approach made sense.”

Our Variable Refrigerant Flow (VRF) system could meet every request on the wish list: quiet operation for customer conversation, a small footprint in tight spaces, high efficiency and an aesthetic fit. Moreover, for the cooler, autumn months, Higgins wanted their concrete floor to give off radiant heating. Using a hydronic heat exchanger, Froom’s team was able to tie in this radiant heating system with the VRF system. The result of the decision to go with VRF over a conventional HVAC system was “our dream tasting room,” according to Higgins.
