Two disclaimers before we start
3
This presentation will be like drinking from a
fire hose

• I constantly try to share too much in too little
  time

4
This presentation will be like riding a
rollercoaster

• I constantly go very fast

5
We live in a world
full of intersections
6
and how we handle these intersections can
determine if we can keep on going
7
or we crash
8
We live at the intersection of
Natural Systems
Human Systems
9
We live at the intersection of
Research (Basic Applied)
Education (Formal Informal)
10
We live at the intersection of
Public, Private, Academic Sectors(Individuals
Partnerships)
Problems, Needs,Opportunities, Desires
11
We live at the intersection of
Science (Social, Life, Physical)
Engineering (All Disciplines)
12
We live at the intersection of
Past
Present
13
We live at the intersection of
14
And we need to remember, that the Future arrives
every second as todays reality, and it does not
have Pause nor Reset buttons.
... and, whether we like it, accept it, or even
care about it, Sustainability and Technology are
an integral part of the Future, if not our only
hope.
15
And, that the choices we have are simple

• Are we going to contribute to make the Future we
  want happen?
• Are we going to just wait and see what Future
  will happen?
• Or, when whatever Future arrives
• Are we going to ask what happened?
• Or, are we just going to say huh, something
  happened ?

16
This presentation is about the reality we want
for the future that is yet to come, specifically
for the future of the Built Environment...
17
a Built Environment composed of Facilities
(e.g., residential, building, and industrial
facilities), and ofCivil Infrastructure Systems
(e.g., transportation, energy, water supply,
waste management, communications)...
18
that nations, public and private sector
organizations, communities, families, and
individuals need and want to exist, develop, and
survive
19
So, let me start by asking two questions
20
Can you imagine a world
21
(No Transcript)
22
without Architects, Engineers, and Constructors,
and the facilities and civil infrastructure
systems we envision, plan, design, build, and
maintain, in response to the problems, needs,
opportunities, and desires of a broad and diverse
range of stakeholders?
23
I did not think so
24
Second, what if Architects, Engineers,and
Constructors could no longer do what we do, how
we do it,andwith what?
25
What we do...
Characteristics and Requirements of a Specific
Facility or Civil Infrastructure System
...how we do it...
...and with what...
Processes for the Delivery and Use of a Specific
Facility or Civil Infrastructure System
Resources for the Delivery and Use of a Specific
Facility or Civil Infrastructure System

So, lets take a quick and closer look at the
Architecture, Engineering, and Construction (AEC)
Industry
28
It is large

• Global 3.2 T
• U.S. Domestic 1.1 T
• Construction 710 B
• Renovation 282 B
• Maintenance 148 B
• Materials 353 B

It is diverse
Source Jack Snell, NIST
30
It has many stakeholders
(Jain et al. 1994 Halliday 1994 Vanegas 1987
Hendrickson Au 1989)
31
It faces many challenges

• Overpopulation, disease, and social, economic,
  and political conflicts
• Widespread infrastructure deterioration,
  pollution, and urban sprawl
• Natural resource depletion and degradation, waste
  generation and accumulation, and environmental
  impact and degradation
• Complex interrelationship between the economic
  development needs and the environmental problems
  resulting from development efforts

32
It takes (in the U.S.)

• 65 of total electricity consumption
• 50 of fossil fuels consumed
• 40 of materials use
• 25 of wood harvest
• 17 of fresh water withdrawals
• 124 trillion gallons/year total water use
• 146,000 gallons/year average household use
• 42 indoors, 58 outdoors
• and much more

(Roodman Lenssen 1996 Loken et al. 1994)
33
It leaves (in the U.S.)

• 136 million tons of construction and demolition
  waste annually
• 8-20 of solid waste
• 25 of CFC emissions
• 36 of CO2 emissions
• 740 million tons of CO2 from commercial buildings
  alone
• 60 Billion in medical expenses due to Sick
  Building Syndrome
• and much more

(Kibert et al. 1994 Zeiher 1996 Tchobanoglous
et al. 1994 EBN 2001)
34
It continues to grow

• Total land area in U.S. 1.94 billion acres
• Developed land in U.S. (excluding Alaska) 98.2
  million acres
• Increase from 1982 to 1997 34
• Average annual increase 2.3
• Increase in urbanized land relative to population
  growth 2.65 times the rate of population growth
• and much more

(EBN 2001)
35
It continues to evolve

• 170,000 commercial buildings constructed annually
• 44,000 commercial buildings demolished annually
• 1.6 million new homes built annually (1.3 million
  single family)
• 245,000 housing units demolished annually
• and much more

(EBN 2001)
36
It leaves a legacy

• 4.6 million commercial buildings
• 101.5 million homes (63.8 single-family)
• 425,000 brownfield sites
• 4 million paved miles
• 35.4 million square miles total paved surfaces
  (public roadways, paved parking areas, and
  driveways)
• More than 50 of wetlands lost in the lower 48
  states between the late 1700s and the mid-1980s
• and much more

(EBN 2001)
37
In other words, we face an unsustainable linear
approach to development
(Inspired by D. Roberts)
38
So, what can we do to address and overcome these
challenges?
39
A wide range of constituencies, not only in the
AEC industry but in other industries as well,
have been attempting for many years the
implementation of possible mechanisms to slow,
reduce, and eliminate these impacts, and even
restore conditions to a better state
40
In other words, they have been striving to
implement sustainability
(Inspired by D. Roberts)
41
However, one problem is that when you start to
discuss sustainability

• Some people strive to use tactics to leave you
• Scared (the possible outcomes)
• Bad (the statistics and blame)
• Guilty (the greater good)
• Confused ( the intellectual base)
• Relieved (the technological fix)
• Although any discussion on Built Environment
  Sustainability (BES) needs to address all these
  points of view, this presentation will strive to
  avoid the polarization they inevitably cause

42
and instead of debating any of these points of
view, focus onwhat could the A/E/C Industry do
to effectively implementBuilt Environment
Sustainability(BES)?
43
The first thing that we can do to implement BES
in the A/E/C Industry is toEstablish, as a
point of departure, the dimensions, influences,
and scales of BES
44
So, from various perspectives...
45
...and at various levels of complexity...
(Inspired by P. Anastas)
46
we need to establish that what we need/want to
sustain are...

Organizations

58
However,There is nothing more tragic than the
death of a beautiful theory at the hands of a
brutal gang of irrefutable facts.
59
and the irrefutable facts are that the AEC
industry

• operates with a Horizontal Tunnel Vision
  within Vertical Stovepipes
• follows a Cradle to Grave path of development
  combined with a Turf Mentality at an industry
  level
• is full of Conventional Enterprises that
  operate with Institutional Amnesia...
• lives in the Jail of the Status Quofurther
  hampered by the Shackles of Quality, Cost, and
  Time within a Commodity and Service Trap

60
and the irrefutable facts are that the AEC
industry (cont.)

• executes AEC projects as an Obstacle Course
  Race with a Herd of Cats who are constantly
  Thumb Wrestling and who suffer from Spatial
  and Temporal Myopia
• needs to overcome its Piece Meal and Rice
  Bowls mentalities, and to avoid all the Islands
  of Execution and Automation

61
In fact, compared to other industries
62
So, in this brutal context, very few theories
have a chance to survive
63
So the second thing that we can do to implement
BES in the A/E/C Industry is toApply a roadmap
and a set of principles for the implementation of
BES that will enable the AEC industry to move
from its current inhibitors to a new set of
enablers
64
From A/E/C industry fragmentation
65
to A/E/C industry collaboration

From a limited and narrow view of A/E/C project
scope
67
to an expanded A/E/C project scope
68
From the Jail of the Status Quo
69
to continuous improvement

• Research Development
• Education Training
• Best Practices
• Lessons Learned
• Creativity Innovation

83
From Islands of Automation
84
to a New Vision of an Integrated and Automated
Capital Projects Industry
85
to a New Vision of an Integrated and Automated
Capital Projects Industry
86
The vision of the future is of a highly
automated and seamlessly integrated environment
across all phases and processes of the capital
project/facility life cycle. All information is
available to whomever needs it, whenever it is
needed, and wherever it is needed.FIATECH, 2003
87
and many, many more
88
The challenge, though, is that all these enablers
require various degrees of change
89
So the third thing that we can do to implement
BES in the A/E/C Industry is toAcknowledge,
address, and manage change, and then just do it!
90
What will be the trigger of change?
Regardless of the trigger, changes toward
sustainability are inevitable, and how
organizations respond to these changes will make
them
end with a Pile of CASH
or end as a Pile of ASH

...You really-shoulda...
...You really-oughta-wanna...
...You really-gonna-hafta...

(Inspired by P. Melhus)
92
So in closing, let me leave you with the
following thoughtWhat if the A/E/C Industry
had?
93
Reliable Data and Analyses of the Economic Impact
of Achieving and Not Achieving BES
A Solid Conceptual Framework and Implementation
Roadmap for BES
A Coordinated Public and Private Sectors National
Agenda for BES
Industry and Multi-stakeholder Alignment and
Partnering toward BES
Reliable Data and Analyses of the Benefits of BES
Public and Private Investment in BES

... and in addition, we were able to overthrow
the Tyranny of the OR
and embrace the Genius of the AND

(Inspired by R. Jackson)
108
and by eliminating the high levels of waste in
the industry, we could pay for all of this and
more
109
Is all this hard to imagine?
Impossible to achieve?
Not really, but it will require some level of
change in In our Paradigms In our Decisions In
our Choices In our Actions
Not really, but it will require some level of
change in In our Paradigms In our
Decisions In our Choices In our Actions
110

• Remember, Sustainability can be implemented
• ... one decision, one choice, or one action at a
  time
• ... one paradigm at a time
• ... one product or one process at a time
• ... phase by phase in a products or a projects
  life cycle
• ... one project or one program at a time
• ... one enterprise at a time
• ... one industry at a time
• ... in a gradual shift to a sustainable future

111
So let me finish by asking you, what if we do not
strive to achieve BES?
