Nestled within the Templeton Gap area of West Paso Robles, California, this unassuming agricultural storage facility is positioned at the base of the 50-acre James Berry Vineyard. Operating independently from the energy grid, this self-sufficient structure takes its resilience from the Templeton Gap region.
Project Name: Saxum Vineyard Equipment Barn
Studio Name: Clayton Korte designs
Location: Paso Robles, California
Fashioned as a contemporary pole barn, the structure utilizes reclaimed oilfield drill stem pipes to serve as the framework for a photovoltaic roof system. The structure also provides shelter for farming equipment, a workshop, maintenance space, and livestock supplies.
Designed to leverage the local climate for optimal cross ventilation, daylight exposure, and solar energy utilization, the repurposed oilfield pipe structure incorporates a laminated glass photovoltaic roof system, producing approximately 1/3 more power than required (around 87,000 kWh annually). This surplus energy eliminates reliance on grid-connected power for both the winery and the vineyard irrigation well pumps through net metering. The laminated glass solar modules function as both the primary roof and the renewable energy generator, eliminating the need for a separate roof with individually mounted crystalline solar panels.
Embracing a minimalist approach, the structure employs salvaged materials chosen for their suitability in the arid climate, regional availability, durability, and low maintenance requirements. The main columns and roof structure are crafted from welded Schedule 40 reclaimed drill stem pipes, ranging in diameters of 2 inches, 3 inches, and 3.5 inches, weathering naturally over time. The lateral load resistance system incorporates diaphragm rod cross-bracing and vertically tensioned cross-braced frames. Laminated glass solar modules, functioning as both the solar system and roofing, are supported on wood and WT steel flitch purlins welded to the pipe trusses. An 8-inch diameter Schedule 40 half-pipe gutter is strategically positioned at the lower end of the roof to facilitate future rainwater harvesting. Shading and filtered privacy for equipment bays are provided by 22-gauge Western Rib Cor-Ten corrugated perforated steel panels.
The use of salvaged materials extends to various aspects of the structure, contributing to sustainability efforts. Barn doors are adorned with weathered steel off-cuts salvaged from adjacent winery shoring walls, arranged in a “calico” pattern to complement the irregularly shaped door panels. Storage boxes feature stained cedar siding on the exterior and unfinished rotary cut Douglas Fir plywood on the interior. Foundation design incorporates pervious gravel paving for open vehicle storage bays and livestock pens, maximizing rainwater filtration into the watershed. An engineered deepened earthwork program enhances the efficiency of structural foundation requirements, reducing the reliance on cast-in-place concrete.
The barn and its renewable energy system epitomize the winery’s dedication to sustainability and harmonious integration with the natural landscape.
