“Can we move nations and people in the direction of sustainability? Such a move would be a modification of society comparable in scale to…the Agricultural Revolution…and the Industrial Revolution…Those revolutions were gradual, spontaneous and largely unconscious. This one will have to be a fully conscious operation…If we actually do it, the undertaking will be absolutely unique in humanity’s stay on Earth.”• William D. RuckelshausSustainability and The Difficult Question of Scale:
Environmental problems have multiple causes across multiple scales. So do the solutions.
Maine Turnpike Authority decides to widen turnpike to alleviate congestion;
Wider turnpike encourages more traffic;
Traffic congestion increases, spills onto secondary roads;
State & towns contemplate widening secondary roads.
Small to Large:
Each farmer wants to earn more;
Each farmer buys more inputs and grows more crops;
Price of inputs rises & price of crops falls;
Each farmer, to break even, buys more inputs and grows more crops.
Multi-billion dollar Federal crop support & offset programs.“Unintended Consequences” Across Scales:
3rd World Micro Credit:
Reduces child mortality;
Lowers population growth.Multiple Benefits Across Scales:
Effects across scales are called “cascades.” We need to create “beneficial cascades”. Pattern Languages can help us do this.
“Patterns of A Conservation Economy”
“A Conservation Economy • What Does A Sustainable Society Look Like?”
Patterns are rules that describe a problem and give a tangible solution that can be locally adapted.
Patterns are linked, from large to small, to form Pattern Languages.
Pattern Languages can be shared, discussed and improved.
Pattern Languages are a common ground for people working in different disciplines and at different scales.
That’s why Pattern Languages are vital for sustainability efforts.Summary: Pattern Languages & Scale
A Pattern doesn’t just describe a solution - it teaches you how to generate the solution, concretely, in the world.
How do I create it?
What is it?
Genes don’t carry descriptions, they carry instructions.
Here’s the result...
Here’s what to do…
Describing the result isn’t the same as giving instructions.
Architecture describing end result.
Architecture showing how to generate a result.
A Pattern helps you understand what to do.
Green businesses use resources efficiently & emphasize broader community benefit for a “Triple Bottom Line”.
A lovely sentiment, but not yet a Pattern.
Describes a worthwhile end, but doesn’t contain instructions.
A “Green Business Rating” might be a Pattern.Not a Pattern: “Green Business”
Celebrate beauty, wholeness and play as central features of life.
We aren’t directly empowered to create something by this.
A description of a lovely outcome, but not generative instructions - not a Pattern.Not a Pattern: “Beauty and Play”
A Pattern is an instruction showing you how the solution can be used repeatedly to solve the problem.
A Pattern is a solution presented as something tangible and desirable that can be created.
A Pattern doesn’t just describe a desirable outcome - it contains instructions for generating the outcome.
A Pattern is like a seed or gene.Summary: Patterns Are Instructions
It describes the general field of relationships that solves a recurring problem in the world.
Specific relationships govern a Pattern, not specific parts.
A Pattern is specific about how things must work and relate to solve a problem.
But a Pattern can be adapted to local circumstances, made of local materials, modified where local culture and customs require.A Pattern Allows Adaptation
The same Pattern expressed in different cultures, contexts and materials.
The process generates the same relationships, but adapts them to a particular setting.

The same process generates endless variety.
“The Problem Is The Solution”
“This is a fundamental view of the world. It says that when you build a thing you cannot build that thing in isolation, but must also repair the world around it, and within it, so that the larger world at that one place becomes more coherent, and more whole; and the thing you make takes its place in the web of nature, as you make it.”- Christopher AlexanderOne Fundamental Process of Creation and Repair
In Nature, the same process grows and heals organisms.
Focus on a problem;
Articulate why it’s a problem;
Look for problem’s cause in failed relationships;
Look for healthy, functioning relationships as an alternative - envision what you really want;
Propose repairs to the relationships;
Describe the repairs as an instruction, so someone else can do it too;
Describe the context in which your Pattern makes sense;
Share the Pattern, and let it be improved by experience and feedback.Summary: “Discovering” Patterns
These Patterns combine to form part of the Pattern Language of these villages.
If you produce these Patterns, one by one, eventually you’ll create streets like these.
Patterns have different scales. Smaller scale Patterns are born from larger scale ones.
Use Patterns in sequence to keep things manageable.
At a given scale, the ideal number of Patterns is between 5 and 9.Summary: Linking Patterns To Form Pattern Languages

Strong “Centers” and Profound Boundaries

Chartres Rose Window
Is made of multiple “centers”, each “center” helping form other “centers”;
Forms profound boundaries that are places in and of themselves;
Is “fractal”, with repeating patterns in space across multiple scales;
Is akin to the geometry of Nature.Summary: Pattern Language Geometry
They ask us to reintegrate our civilization with Nature.
“Regenerative design requires that we participate with nature in a mutually beneficial relationship…(and) an awareness of what gives health to a place… so that the systems (human and natural) have an opportunity to organize in self-healing relationships.”
