Timmons Design Engineers was commissioned by Freebairn-Smith & Crane to provide Mechanical, Plumbing and Sustainable design for the new Ridge Vineyards Montebello Winery administration building in Cupertino, CA. The HVAC design integrates energy efficient technologies including radiant heating and cooling throughout the office space in which the conditioning hot and cold water are provided by a closed loop geothermal heat pump circulating water underground. The building is also designed to maximize daylight usage and incorporates automated external mechanical louvers in the clerestories to shade from direct sun glare and heat gain on very warm summer days. The cooling design of the building is intended to maximize passive natural ventilation through operable windows, clerestories and large bay doors throughout the building, which will be supplemented by the cooling effect of a cooled radiant floor. To meet the clients goal of minimizing environmental impact, a grid-intertied photovoltaic system designed by TDE will be installed to provide solar electricity.
