Working with Wholes

"Mythologist Joseph Campbell once said, "People who don’t have a concept of the whole can do very unfortunate things." But the corollary is rarely considered: People who understand the whole can do very fortunate things." - Linda Booth Sweeney Humans possess the capacity to think in wholes – to see whole systems at work. Our ancient ancestors did so without the aid of our current dependence on machines. Everything in creation was viewed as inter-related and connected. Then a new story emerged, slowly and then almost all at once. [...]

ASHRAE 90.1 Appendix G Fan Power Calculator – August 2020 Version

7group has released an updated version of its well-known (at least within the energy modeling community) ASHRAE 90.1 Appendix G Fan Power Calculator. This tool has been used by countless energy modelers to aid in the development of their Baseline energy models, often for projects pursuing LEED certification. The original calculator included the Baseline model fan power calculations for the 2004 and 2007 versions of ASHRAE 90.1, which were referenced by LEED v2 and LEED v3, respectively. The updated version incorporates changes made in each subsequent version of ASHRAE 90.1, [...]

Regenerating the Essence of Walnut Acres

If you are not familiar with the story of Walnut Acres, this farm was one of the original organic farms in Pennsylvania.

You can find out more about the original farm and [...]

Becoming Regenerative – GreenCon 2019

Regenerative is not something you do, it is something you become. Everyone we have met wants to work on something that positively contributes to some good in the world, some higher purpose beyond just meeting their own individual needs. We believe that this is an innate quality of human nature. Of course circumstances in one's life can shift this need and turn it inward but we are all born with this quality of caring for something bigger than just ourselves. Doing this work in the world requires that we [...]


The entirety of our world is alive! We are a part of, and integral to this living, breathing, moving, speaking, listening, touching, defecating, squirming, decomposing, growing, interacting, complex whole of Life. We are surrounded by, immersed in, and a part of the living world. We co-inhabit a living planet in reciprocal relationship with all other living beings. Without our fellow beings we would not long survive. We depend on other beings to pollinate plants, produce food, provide air to breath, clean water, regulate climate, decompose waste, make edible matter [...]


Of course we made up synthegrative, so don’t try to look it up. This “word” reflects our approach to thinking, learning, projects, story and process. It combines real words, synthesis – a combination of ideas to form a theory or system, and integrative – serving or intending to unify separate things; to create a systemic vision of wholes which are greater than the sum of their parts. This reminds us that our work in regenerative design must begin with working on whole systems and not just the parts.

Our synthegrative posts will explore our thoughts, beliefs and ideas. We will share news about our events, our projects and our work. We will tell our story and the stories we find along the way.
