PLACES TO INTERVENE IN A SYSTEM:
12. Constants, parameters, numbers (subsidies, taxes, standards)
11. The sizes of buffers and other stabilizing stocks, relative to their flows
10. The structure of material stocks and flows (transport networks, population age structures)
9. Length of delays, relative to the rate of system change
8. The strength of negative feedback loops, relative to the impacts they are trying to correct against
7. The gain around driving positive feedback loops
6. The structure of information flows (who does and does not have access to what kinds of
information)
5. The rules of the system (such as incentives, punishments, constraints)
4. The power to add, change, evolve, or self-organize system structure
3. The goals of the system
2. The mindset or paradigm out of which the system – its goals, power structure, rules, its culture-
arises
1. The power to transcend paradigms

2. The mindset or paradigm out of which the
system – its goals, power structure, rules, its
culture-arises
The shared idea in the minds of society, the
great big unstated assumptions—unstated
because unnecessary to state; everyone already
knows them—constitute that society’s
paradigm, or deepest set of beliefs about how
the world works.
-D. Meadows.

What paradigmatic assumptions do we
follow?
There is a difference between nouns and verbs.
Money measures something real and has meaning.
(people who are paid less are literally worth less).
Growth is good.
Nature is a stock of resources to be converted for
human purposes.
One can own the land.

Paradigms are the sources of systems
From them, form shared social agreements about the
nature of reality, come system goals and information
flows, feedbacks, stocks, flows, and everything else
about systems.

Rhizome
Describes the relations and connectivity of things.
A rhizomatic way of thinking.

Rhizome
For the best and worst. Rats are rhizomatic. Crab
grass too.

Not a tree
Not – a tree which has a starting point and from there
branches out in a predictable path.
Not tree-like thinking. No checklists. Or software-
driven mindmaps.
10November 4, 2014
Assemblage
A rhizone forms an assemblages. An assemblage is
a gathering and grouping of things.

Anti-Oedipus
Capitalism sets free desiring-production even as it
attempts to rein it in with the institution of private property
and the familial or “Oedipal” patterning of desire;
schizophrenics are propelled by the charge of desiring-
production thus set free but fail at the limits capitalist
society proposes, thus providing a clue to the workings
of desiring-production.

Anti-Oedipus
Desiring-production does not connect “with” reality, as in
escaping a subjective prison to touch the objective, but it
makes reality, it is the Real.
14November 4, 2014
A Thousand Plateaus
What the schizophrenic experiences is nature as a
process of production.
15November 4, 2014
A Thousand Plateaus
It is probable that at a certain level nature and industry
are two separate and distinct things: from one point of
view, industry is the opposite of nature; from another,
industry extracts its raw materials form nature; from yet
another, it returns it s refuse to nature; and so on.
16November 4, 2014
A Thousand Plateaus
Even within society, this characteristic man-nature,
industry-nature, society-nature relationship is responsible
for the distinction of relatively autonomous spheres that
are called production, distribution, consumption.
17November 4, 2014
A Thousand Plateaus
But in general this entire level of distinctions, examined
from the point of view of its formal structures,
presupposes (as Marx has demonstrated) not only the
existence of capitalism and the division of labor, but also
the false consciousness that the capitalist being
necessarily acquires, both of itself and the supposedly
fixed elements within an overall process.
18November 4, 2014
A Thousand Plateaus
For the real truth of the matter- the glaring sober truth
that resides in delirium – is that there is no such things
as relatively independent spheres or circuits.
19November 4, 2014
Society of control
A worldwide circulation of electronic circulation. Control
by way of incessant cybernetic feedback. Poling and
marketing. The expression of meaning and
communicating – the shallow form of advertisement. Our
normal human activities reduced to economic value.
Invent ways of thinking to enable people to break free
from cultural relativism.

BUILDINGS AND CLIMATE
CHANGE
Buildings account for 40% of total energy used and generate 45% of total US CO2 emissions
Hefty contribution to Global Warming and Climate Change
US adds ~6 billion tons of CO2 emissions a year, world’s total: ~34 billion
CO2 emissions per capita in US: 17.3 tons, China 7.2 tons, EU average: 7.5, average for the world: 4 (July 2011 data)
Renewable energy growth too slow (25%) compared to fossil fuel use increase in the last decade (41%)
Effects of self-acceleration of global warming (“tipping points”) are very serious
With current trends we are not on a path to limit warming to 2o C by 2100

Why do we build skyscrapers
November 4, 2014
The ancient Egyptians built pyramids because they believed
in an afterlife. We build skyscrapers because we believe that
space in downtown cities is enormously valuable.

Developed by the U.S. Green Building Council (USGBC),
LEED is intended to help building owners and operators
be environmentally responsible and use resources
efficiently.

HOW DOES THIS BUILDING
PERFORM?
Praise: LEED Platinum certification—the first ever for a skyscraper—and the $947,583 in incentives from the New York State Energy Research and Development Authority, and endorsements from Al Gore.
Condemnation: According to data released by New York City in 2012, the Bank of America Tower produces more greenhouse gases and uses more energy per square foot than any comparably sized office building in Manhattan. It uses more than twice as much energy per square foot as the 80-year-old Empire State Building

FAILURE OF MODELED METRICS,
VS. ACTUAL PERFORMANCE DATA
The USGBC, which operates LEED, similarly says it has no control over how the buildings it certifies are used. But LEED certifies new buildings before they are even occupied, basing its ratings on computer models that often end up overestimating a building’s performance.
If you can model, you can’t necessarily manage.

PASSIVE
HOUSE
November 4, 2014
38
AN ATTEMPT AT PARADIGMATIC
CHANGE: PASSIVE HOUSE
Adopted in the 1990s in Illinois, then Germany
Was proven economically viable; ~10% increase in construction cost while achieving 80% reduction in energy use of the building for a “new start”
BASED ON MODELED ENERGY, BUT NOT CERTIFIED PASSIVE HOUSE UNTIL THE HOUSE IS MEASURED.
November 4, 2014
39
MODELED VS. MEASURED
LEED, NYSERDA:
Calculations are predictions, performed in excel. If/then. Not based on actual use, actual staffing actual choice of lighting fixtures once the building is functioning three years later.
PASSIVE HOUSE:
Measured energy, air flows determine the kilowatt hour energy required to keep the building climate comfortable.

THERMAL ENVELOPE, BEFORE AND AFTER PASSIVE
HOUSE RETROFIT:
MEASURABLE PERFORMANCE OF PH IS “BUILT IN”
INTO PH STANDARD:
Criterion #1: total energy has to be less than
38 kBtu/sf/yr
Note: this is primary (or source) energy, not site energy.
About 3 times more energy needs to be used at the source to
generate energy we use on site due to generation inefficiency
and transport losses. Source energy is the most relevant
measure of carbon emission.
47
Criterion #2: heating and
cooling energy limits:
4.75 kBtu/sf/yr, each
This is like heating the
whole 2000 sf house with
a hair dryer 9 hrs a day
(and making it nicely
warm!)
1 kBtu=0.3 kWh
48
VERIFIABLE METHODOLOGY IS BUILT INTO PH
STANDARD
Criterion #3: air
tightness (0.6 air-
changes per hour
at 50 pascals)
Measured through
blower-door test to
assure that
standard is met
Passive House air
leakage is about
10 times less than
standard new
construction
ECONOMIC FEASIBILITY VS. BRANDING
Focus on economic feasibility:
Shift money from mechanical systems to the building envelope
Long lasting, high quality construction
Focus on comfort:
Healthy interior environments due to continuous ventilation
“Year-round barefoot indoor comfort on a dime” No drafts/uniform temp.
Focus on predictability:
Computer modeling with PHPP (Passive House Planning Package) and WUFI (Heat and Moisture Dynamics* modeling)
Optimization of performance w/ PHPP/WUFI
Certification from Passive House Institute US (PHIUS)

Who has changed paradigms?
50November 4, 2014
Whether it was Copernicus and Kepler showing that the earth
is not the center of the universe
Or Einstein hypothesizing that matter and energy are
interchangeable
Or Adam Smith postulating that the selfish actions of
individual players in markets wonderfully accumulate to the
common good
People who have managed to intervene in systems at the
level of paradigm have hit a leverage point that totally
transforms systems.
So how do you change paradigms?
51November 4, 2014
D. Meadows paraphrasing Thomas Kuhn:
You keep pointing at the anomalies and failures in the old
paradigm, you keep speaking louder and with assurance
from the new one, you insert people with the new paradigm
in places of public visibility and power.
You don’t waste time with reactionaries; rather you work with
active change agents and with the vast middle group of
people who are open minded.
ASSIGNMENT What part of the system of how we make and maintain our
buildings, interests you the most?
What are the anomalies and failures that irk you?
What possibilities do you see?
