Centennial Sermon – Design, Ecology, Ethics, and the Making of Things (Study Notes)

Setting and Context

Centennial sermon delivered by architect William McDonough at the Cathedral of St. John the Divine, New York City, 7 Feb 1993.
Purpose: Offer a forward-looking “saving truth” on design, ecology, ethics, and human intention.
Dean James Parks Morton frames the talk as prophetic guidance for the 21st century.
Speaker’s stance: Humility in a cathedral—a built form embodying humanity’s highest aspirations and illustrating design’s sacred dimension.

Design as the First Signal of Human Intention

Design is the translation of human will into physical form; therefore every artifact carries ethical weight.
Louis Kahn anecdote (via Vincent Scully): beauty lies not only in a dome’s rise skyward but in how it meets the ground—emphasizes full life-cycle thinking.
Core ecological maxim: “Things we make must rise from the ground and return to it—soil to soil, water to water—without harm.”

Historical Lessons: Mass vs. Membrane

Architecture has long balanced two elemental strategies:
- Mass (e.g., adobe walls, Jericho’s fortifications)
- Membrane (e.g., tents, fabric enclosures)

Mass Architecture

Ancient adobe builders mastered “thermal capacity” and “lag.”
- Thickness calibrated so heat absorbed by day is released at night in winter, or coolness retained in summer.
- Roof straw provided insulating “resistance.”

Membrane Architecture

Black Bedouin tent achieves five simultaneous functions:
1. Creates deep shade, lowering sensible temperature from $120^\circ\text{F} \to 95^\circ\text{F}$ .
2. Coarse weave yields diffuse, jewel-like interior light (“a million fixtures”).
3. Stack effect: hot interior air rises through fabric, drawing breeze, dropping temp to $90^\circ\text{F}$ .
4. In rain, fibers swell; weave becomes watertight.
5. Portability—can be rolled up and moved.
Gothic cathedrals = historic experiment merging mass with luminous membrane (stained glass).

Modern Architecture Critiqued

Arrival of cheap glass + cheap fossil energy ended solar-responsive design.
Most architects can’t find true south—symbolic of disconnection from sun.
Cultural design strategy: “If brute force or massive energy doesn’t work, use more.”
Le Corbusier’s dictum “A house is a machine for living in” evolved into buildings designed around machine needs, not human needs.
Sealed glass boxes deprive occupants of natural air/light, causing stress and indoor-air toxics exposure.
- Thousands of chemicals inhabit interiors.

Living Machines vs. Machines for Living In

Biologist John Todd: favor living systems that meet needs with clean water, safe materials, durability, and current solar income.

Ecology, Economy, and True Accounting

Etymology:
- Ecology: $Oikos + Logos$ = “household logic”
- Economy: $Oikos + Nomos$ = “household management/law”
Flawed monetary metrics:
- Example: Exxon Valdez clean-up inflated GNP, mis-labeling disaster as prosperity.
- Natural resources absent from asset side of ledger—e.g., forests valued only after felling.

Three Fundamental Laws of Natural Design

Closed nutrient loops: waste = food; no concept of garbage.
Energy budget: operate on current solar income, never deplete past reserves or borrow from future.
Biodiversity maintains resilience and prevents entropy.

The Designer as Leader

Emerson’s sail vs. steamship trip: solar-powered, craft-oriented vessel contrasted with coal-fired, pollution-laden technology—both design outcomes.
Peter Senge’s Learning Lab: true leader on a ship is its designer; operations follow design.

From Consumers to People with Lives

McDonough critiques U.S. identity shift to “consumers with lifestyles.”
Most goods marketed as “consumables” are actually non-consumable; they must be discarded.
- Television set example: $4{,}060$ chemicals, $18\text{ g}$ methyl-mercury, off-gassing, implosion risk—would you invite this into your home?

Michael Braungart’s Product Typology

Consumables (biological nutrients)
- Designed to safely decompose: shampoos in beet-plastic bottles, carpets → $CO<em>2$ + $H</em>2O$ , lignin furniture.
- Should never enter landfills; instead return to soil.
Products of Service (technical nutrients/durables)
- TVs, cars, appliances.
- Not sold; licensed. After use, returned to manufacturer for disassembly & re-use—nutrient cycles within industrial metabolism.
Unmarketables
- Nuclear waste, dioxins, chromium-tanned leather; nobody should buy.
- Must be sequestered in secure storage until safe solutions found.

Case Studies in Applied Ecological Design

1. Environmental NGO Office

Client threatened lawsuit if anyone became sick from indoor air quality.
Result: discovered virtually all conventional building materials are toxic; began collaborative material-innovation work.

2. New York Men’s Clothing Store

Used two English oaks for paneling; offset by planting $1{,}000$ replacement oaks.
Story invoked: Oxford’s New College foresters planted replacement oaks in 17th c. anticipating beam rot centuries later—long-term cultural stewardship.

3. Warsaw High-Rise Competition (Winner)

Concrete base integrates WWII rubble—visceral “phoenix rising.”
Recycled-aluminum skin.
$13\text{ ft}$ clear floor heights → future conversion to housing (long life).
Operable windows; max occupant distance to window = $25\text{ ft}$ .
Climate-offset mandate: plant $10\text{ mi}^2$ ( $=6{,}400\text{ acres}$ ) of forest to balance construction & operational energy.
- Client accepted; cost < small portion of advertising budget.

4. Lawrence, Kansas Big-Box Retail Store

Initial tension over chain’s impact on small towns.
Design moves:
- Switched structural system: steel ( $300{,}000\,\text{BTU}/\text{ft}^2$ ) → wood ( $40{,}000\,\text{BTU}/\text{ft}^2$ ).
- Wood sourced only from biodiversity-protective forests (e.g., Madison & Taylor family lands).
- Eliminated CFCs; pioneered daylighting research.
- Building planned for later housing conversion.

5. Frankfurt Day-Care Center

Greenhouse roof functions: lighting, heating (air & water), cooling, ventilation, rain shelter—"high-tech Bedouin tent.”
Engineers sought total automation; McDonough insisted on child-operated controls (open window/close shade). Emphasizes living interaction.
Added community laundry to tap solar-heated water.
Fossil-fuel-free operation; in $50\text{ yrs}$ when fuels scarce, building delivers hot water & social hub while having repaid embodied energy debt.

Ethical Evolution & Declaration of Interdependence

Expansion of rights timeline:
- Magna Carta → landowning white men → Emancipation → Women’s suffrage → Civil Rights Act (1964) → Endangered Species Act (1973) granting rights to non-human species.
Jefferson today would draft a “Declaration of Interdependence” linking human prosperity to that of other species, forbidding remote tyranny.

Collapse of Traditional Sovereignty & Leadership Void

Global finance (computerized trading) eclipses national control.
Technological transparency (satellites at $10\text{ m}$ resolution) exposes deception (e.g., Chernobyl).
Earth Summit: >100 heads of state, yet paucity of genuine leaders.

Dominion, Stewardship, and War on Life

Misinterpretation of Genesis dominion: true dominion implies stewardship—cannot rule over what one destroys.
Current industrial design = war on life:
- Activities listed: deforestation, incineration, drift-netting, coal burning, chlorine bleaching, topsoil loss, pesticide overuse, habitat destruction, damming rivers, toxic & radioactive waste production.
- Produces a global machine "for dying in, not living in.”
Jordan Valley anecdote: war = “when they kill your children.” Industrial war similarly endangers future generations.

Call to Action & Closing Principles

Cease designing everyday objects for killing; transcend focus on explicit weapons.
Recognize every natural event as design; align human intention with natural law.
Honor sacred forces larger than ourselves by:
1. Cycling materials safely (waste = food).
2. Powering operations with current solar income.
3. Preserving and celebrating biodiversity.
Move from industrial idiom of domination to an ethic of interdependence, gratitude, and peace with the natural world.
