Regenerative Design
What is Regenerative Design?
Regenerative design uses passive solar as a way to build. We feel this is a wonderful journey into the realm of harnessing nature's generosity! Designing developments, homes, and farm buildings with passive solar principles is a truly regenerative approach, allowing us to work with the sun's energy rather than against it. It's about optimizing the free gifts of sunlight, water, and carbon dioxide by creating environments that naturally regulate temperature and light.
At its heart, passive solar design is an elegant dance with the sun's energy flow, a core ecological first principle. It seeks to maintain a dynamic equilibrium within the building, leveraging natural processes to achieve desired conditions without relying on external, energy-intensive inputs. This approach builds antifragility into your home, farm, and community infrastructure, making it more resilient to energy price fluctuations and grid instabilities.

Regenerative Design and Passive Solar
- Regenerative design is a broad, overarching philosophy aimed at creating living systems that actively improve and restore ecological function and vitality. It's about the entire system's health and evolution.
- Passive solar is a specific, focused technique within building design, primarily concerned with energy efficiency and thermal comfort by leveraging solar radiation. It's a component that can contribute to a broader regenerative design, but it is not the entire philosophy itself.
Core Principles of Passive Solar
Passive solar design relies on five fundamental elements to capture, store, and distribute solar energy:
- Windows (Collector): This is the glazing (windows, skylights, transparent panels) through which sunlight enters the building. For both farm and residential buildings, as well as larger, community developments, this often means south-facing windows (in the Northern Hemisphere) or translucent roofing materials. The size and orientation are crucial for maximizing solar gain during colder months.
- Absorber: This is the dark, heat-absorbing surface that the sunlight strikes after entering the aperture. In a building, this could be a dark concrete floor, a masonry wall, or even water-filled containers. The absorber converts solar radiation into heat.
- Thermal Mass: Materials with high heat capacity (like concrete, stone, brick, or water) are used to store the absorbed heat. This thermal mass slowly releases the heat when the ambient temperature drops (e.g., at night), maintaining a more stable internal temperature. This is a beautiful example of managing energy flow and dynamic equilibrium within a built system.
- Distribution: This refers to how heat moves from the absorber and thermal mass throughout the building. Natural convection (warm air rising, cool air sinking) is the primary passive distribution method. Strategic placement of vents, open floor plans, and even fans can enhance this.
- Control: Overheating in warmer months is a key challenge. Control elements include overhangs, shading devices (e.g., deciduous trees, awnings), ventilation strategies (cross-ventilation, stack effect), and insulation. These help regulate the amount of solar gain and prevent excessive heat buildup, maintaining the desired dynamic equilibrium.
Benefits from a Regenerative Perspective
- Energy Efficiency & Cost Savings: By leveraging the sun's free energy, you drastically reduce reliance on fossil fuels for heating, aligning with the principle of internalizing costs and building economic resilience.
- Improved Environmental Conditions: More stable temperatures, better natural light, and improved air quality (due to natural ventilation) create healthier environments for plants, animals, and people. This supports the inherent capacity of living systems to heal and thrive.
- Reduced Carbon Footprint: Less energy consumption means fewer greenhouse gas emissions, contributing to climate adaptation and carbon sequestration goals.
- Enhanced Resilience: Buildings designed with passive solar are inherently more resilient to power outages and energy price volatility, embodying antifragile design.
- Support for Biological Processes: Optimal environmental conditions can indirectly support the soil microbiome (e.g., through reduced energy demands for heating, allowing more resources for soil-building practices) and plant physiology (e.g., consistent temperatures for growth, better light for photosynthesis).
Our Practitioner - Carl Welty
Carl Welty has over 35 years of experience in the field of architecture. Carl provides full service architectural and planning. He collaborates with planners, landscape architects, and other design professionals with extensive history in the State of California.
Carl is committed to creating an architecture that connects human beings to nature–not as outside observers but as full partners in the complex web of nature’s closed-loop systems. Carl is a proponent of Regenerative Design, the idea that we can create buildings and communities that generate more resources (energy, water, and building materials, to name a few) than they consume. Resource efficient, more resilient building is good ecological thinking and essential for regenerative design.
Coordinated CFS construction combined with technology to reduce material consumed and increase construction precision will allow us to deliver exceptional value at time of construction and added value over the life of the building with reduced life cycle costs..
Designing in partnership with nature means more than building efficient buildings that consume fewer resources: wasting less is good, but we can do better than just wasting less. Carl is a proponent of regenerative design, the idea that we can create buildings and communities that generate more resources (energy, water, and building materials), and at the same time restore native habitat.
Carl's work focuses on affordable, energy-efficient design and durable, resilient building systems. Carl advocates leveraging natural systems including solar orientation and climate appropriate principles to create cost-effective solutions for energy efficiency of structures with little or no increase in construction costs, and building durable, low-maintenance, resilient structures (increased fire, mold, and termite resistance) by incorporating well-tested alternative construction materials. Moreover, designing with natural systems can inspire beautiful, meaningful architecture.

Architect Carl Welty: We have engaged Architect Carl Welty to query San Diego County Planners on what is allowed with our current zoning and help us design a comprehensive site plan with a phased approach. Carl specializes in designing buildings that leverage natural systems and resilient design. Our goal is to build off-grid residences, working buildings, and multipurpose spaces for education, research, and vocational training to promote ecosystem support services and regenerative agriculture on our 120 acre ranch+olive grove+orchards. Carl's designs will leverage natural systems like solar orientation to absorb and store heat directly from the sun in the winter and nighttime ventilation for zero energy cooling in the summer; we should be able to provide thermal comfort with zero energy from external sources and solar panels. These structures will also be constructed of materials that will be durable, resilient, and resource efficient, utilizing steel framing and non-combustible building materials to mitigate risk to our buildings during future wildfires.
For inspiration, Carl and Lee visited Apricot Lane Farms this past July, a 234 acre farm located north of Los Angeles and made famous by the film, The Biggest Little Farm. Their commitment to regenerative agriculture is impressive and being a passionate vermicomposter, Lee's favorite part was their Fertility Center, which contained a 40-foot worm bin! Carl also draws inspiration from Village Homes, and will integrate food forests and native plantings in his design to maximize water outputs and create enhanced, sustainable living conditions. Carl's approach emphasizes connecting humans to nature, not as outside observers, but as partners in nature's complex systems. We appreciate Carl's help and architectural vision as we develop a site that enhances our awareness of the natural environment, sustains our existence on the land, and ultimately benefits surrounding ecosystems.
