Envelope materiality : light and heavy in wineries : the case of "Santa Ana" winery, in Mendoza, Argentina

In a winery, energy flux exchange and thermal inertia of the envelope are crucial due to the constant need for stabilized temperatures. As a consequence, energy consuming systems like serpentine pipes inside tanks control temperature during fermentation; and air conditioned equipment maintains the appropriate microclimate in oak breeding barrels rooms. “Santa Ana” Winery, located in Mendoza (Argentina), presents two types of envelope materiality: one heavy (mainly adobe walls ¿¿= 0.81W/mK) for fermentation and breeding stages and one light (mainly galvanized steel sheets ¿¿= 45 W/mK) for the storage stage. In both cases the roof is insulated. A complete envelope analysis was made, data from auxiliary energy demand was collected and summer in situ temperature measurements were performed at critical control points. Also, recommendations to environmentally refurbish these envelopes are presented as a light/heavy equilibrium that could serve its purpose with a response from low energy architecture is needed.Peer Reviewe
