Yountville Town Center

After years of planning, the completed Yountville Town Center weaves new and existing buildings and outdoor rooms into a place designed to enrich community life right on main street in the middle of town. The new Community Center building, housing a branch library, program spaces and a large multi-use room, opens onto a new Town Square framed on either side by the existing Community Hall and Post Office. Building exteriors blend with the rural character, while inside the spaces are light and airy. The large multi-use room is a pleasant surprise, day lit by a ridge skylight and supported by unique wood and cable trusses. Through collaboration, the design integrates a range of green features – passive design, efficient technologies and green materials – setting the project up for LEED Platinum and energy savings of 44% over Title 24. Since opening, the town center has become a hub of activity. By design and location, it serves as the town’s living room and a great source of civic pride.

In 1998 a small rural town embarked on a planning process that envisioned an expanded town center for its residents in the middle of town. This original vision of was broadened to include green features aimed at reducing the project’s carbon-footprint and serving as a local model for sustainable development. With intensive community participation and support, the project was opened in late 2009. Numerous sustainable design decisions – passive design, daylighting, efficient technologies, green materials and design of flexible multi-use spaces – have the project on track for LEED Platinum.

The new town center weaves new and existing buildings and outdoor rooms into a collection of spaces designed to enrich community life. A new town square, opening out from the new Community Center and framed by the existing Community Hall and Post Office, serves as both a civic venue and a place for chance encounters. The Community Center building houses a branch library, meeting and program rooms and a large, daylit multi-use space that accommodates everything from after-school programs to community celebrations. Barn doors extend the room onto the adjacent BBQ patio.

Building exteriors refer to the local vernacular with simple building massing, deep porches and familiar materials. Walks and bike paths connect the center to surrounding neighborhoods and main street activities. By location and design the town center the community’s shared living room and a source of civic pride.

Bioclimatic Design

Passive strategies include daylighting, shading and natural ventilation. The highly insulated building envelope includes low-e2 windows, exterior sunshades and “cool” standing seam metal roofs. Light-colored paving and ample tree canopy further reduce heat island effect and minimize cooling loads. A combination of operable skylights, controlled by CO2 and rain sensors, and windows provide natural ventilation and balanced natural illumination.

Energy-efficient systems feature ground-source heat pumps for heating and cooling and roof-mounted photovoltaic laminates for the new and existing buildings. Energy models predict energy savings of over 53% with PV’s providing 25% of power needs. Building controls serve interior rooms independently, maximizing energy efficiency and thermal comfort.

Water Conservation

Site design reduces storm runoff by 40% over pre-construction conditions. Water conserving plumbing fixtures reduce domestic water use by 30%. Harvested rainwater, drip irrigation, subsurface irrigation and drought tolerant native plants reduce irrigation water by 51%.

Building materials were selected to minimize life-cycle impacts, blend with the rural architectural character and provide light and airy interiors free of formaldehyde and VOC’s. Buildings are clad in durable, recycled content cement-fiber shingles and metal roofs. Porches and entrances are regionally harvested western red cedar. Slatted wood ceilings are locally sourced white pine. Over 75% of the wood is certified FSC.

Carbon reduction: Embodied carbon was reduced by 280 tons – 80 from the 70% slag concrete and 200 from reusing (and not replacing) the existing Community Hall. Annual carbon saving from operations is estimated at 80 tons – 50 from efficient mechanical systems and 30 from PV’s.

Notable Accomplishments

  • Harvested rainwater, drip irrigation, subsurface irrigation and drought tolerant native plants reduce irrigation water by 51%.
  • Water conserving plumbing fixtures reduce domestic water use by 30%.
  • Over 75% of the wood is certified FSC.
  • Carbon reduction: Embodied carbon was reduced by 280 tons.
