This farm stand is designed as a model for sustainable construction, demonstrating how buildings can be functional, beautiful, and environmentally conscious. The structure showcases a unique blend of traditional and cutting-edge techniques, minimizing our environmental impact while being able to operate efficiently.
Features of the Net-Zero Farmstand
Carbon Positive Structure
The hybrid timber frame clad in cross-laminated timber (CLT) and wood fiber insulation is a prime example of carbon positive construction. Because trees capture carbon as they grow, their use in construction has a positive environmental impact.
Wood timber, a naturally renewable resource, has a smaller carbon footprint compared to other building materials like steel or concrete.
Passive House Design
The building utilizes passive house strategies to minimize energy use. Carefully positioned windows maximize natural light and warmth in winter, while deep overhangs shade the space in summer. Operable skylights, sliding doors, and large ceiling fans promote natural ventilation, further reducing the need for mechanical heating and cooling.
Net-Zero Energy
A rooftop solar array, strategically positioned on the south-facing roof, generates clean electricity to power all structures on the farm.
Airtight Insulating Envelope
Similar to an insulated cooler, a tightly sealed envelope minimizes energy loss. This is achieved through features like: tightly sealed doors, highly efficient, triple-glazed windows, thick, layered wood insulation throughout, continuous air barrier to seal against air leaks, and a recycled foam glass gravel foundation (instead of traditional gravel).
Ventilation with Heat Recovery
A Dedicated Energy Recovery Ventilator (ERV) removes stale air and supplies fresh, filtered air to the building. Importantly, it recovers heat from the outgoing air, preheating incoming fresh air and minimizing energy consumption.
Thank you to Payette for their generous pro bono design and architectural services. Led by Kevin B. Sullivan, FAIA, Principal-in-Charge, and Wesley Schwartz, AIA, Project Architect, Payette helped us to envision a model of sustainability and make thoughtful choices on building materials to help realize that vision. We couldn’t have done it without the generosity and expertise of these business partners:
