What is Sustainability?
 Sustainability is a set of environmental, economic and
social conditions in which all of society has the capacity
and opportunity to maintain and improve its quality of life
indefinitely without degrading the quantity, quality or the
availability of natural, social and economic resources.

Sustainability – Reliability, resilience, affordable,
supportable, balanced, efficient, effective, strategic focus….

What is Sustainable Civil Infrastructure?
 Sustainable civil infrastructure provides environmental,
economic and societal well-being, now and for the future
(ASCE)
 Policies, approaches and investments that consistently
provide effective systems over the long term with adequate
operations,maintenance and replacement (USEPA)
What is Green Infrastructure?
 An array of products, technologies and practices that use
natural systems (or engineered systems that mimic natural
processes) to enhance overall environmental quality and
provide utility services (USEPA)

Repairing, Rebuilding, Expanding
 ASCE Infrastructure Report Card, 2009
 High U.S. unemployment rate and
focus on creating jobs, economic
competitiveness
 Sustainability principles should
increase:
 value proposition,
 effective project delivery,
 political and stakeholder
acceptance,
 resilience and effectiveness
7
Infrastructure Condition
 Leaking pipes lose an
estimated 7 billion gallons
of clean drinking water a
day
 An estimated 10 billion
gallons of untreated
wastewater are discharged
each year from aging
systems
8
Importance of Our Nation’s
Infrastructure Systems
 All contribute directly and
substantially to our nation’s
productivity and quality of life
 How efficiently and effectively
these systems function is directly
related to…
“Clean drinking
water rated as #1
advancement in
the last
millennium.”
 Design
 Maintenance
 improvements

Infrastructure Challenges
“Either the country can risk further productivity
decline, transportation congestion and potential
catastrophes from dilapidated systems or it can develop
new networks . . . to accommodate the expected 100
million in population growth over the next generation.”
- Ernst and Young, Infrastructure 2009: A Pivot Point
10
Sustainable Development
Problems –
 We’re using up natural
resources and ecological
carrying capacity faster
than it can be replaced,
replenished or restored
 We’re not replacing or
fixing the infrastructure in
a way that conserves or
restores natural resources
and systems
 We’re working with
infrastructure that was
built using old designs and
approaches
11
“You cannot solve a problem with the same sort of
thinking that created the problem”
- Albert Einstein
12
Which Future Will We Choose?
 Repairing our infrastructure
the same old way
OR
 Building a sustainable
infrastructure for the future
13
Sustainability in Buildings
 LEED rating system has
transformed the building
industry
 Application across the
U.S.
 Created a new value
proposition for buildings
14
What About Infrastructure?
 No overall sustainable infrastructure rating system
 Many rating systems at the sector-specific level
 Infrastructure presents a different challenge compared to
buildings:
 Building design and construction controlled by a single
organization
 Infrastructure – Public nature of civil and public works
projects affect/ benefit macro ecosystems, communities and
regions;
 Need to consider the description of public support and the
more efficient use of materials, resources, interference or
impact on public expectations – sustainability needs to pay
for itself!
15
Guidelines and Criteria for Assessing
Sustainability
 Prompts sustainable thinking
 Stimulates innovation at all project stages
 Identifies strengths and weaknesses
 Assists risk management
 Allows continual monitoring of performance
 Demonstrates contribution to sustainable development
 Encourages best management practice
 Provides transparency of approach
 Flexibility for selected application
16
Delivering Sustainability Infrastructure
 The Traditional Triple Bottom Line – “Outcome Principles”
– social, economic and environmental.
 Acknowledges that current state can be insufficient and that
there are opportunities to improve performance of our activities;
 How Do We Achieve TBL - “Process Principles” – ethical,
stakeholder and governance.
 Describes the approach to be adopted in behavior and decision
making and sustainable outcomes are possible when issues are
considered broadly and collaboratively.
 In these six Principles, there are 3 levels of performance.
 Preventing harm
 Preserving current value
 Creation of positive or restorative value

Sustainability and Rating Systems?
 Sustainability is not achieved by a uniform model or single
approach because of the varying contexts, environments,
community/ stakeholder/ physical needs;
 Technology and performance efficiency are enablers to
achieve desired outcomes but the public interest is met
through behaviors and informed decisions;
 A rating system :
 Creates a framework of objective measures;
 Provides guidance that can influence performance goals and
approaches;
 Promotes project resilience, balance and strategic focus.
20
Goals for the Rating System
 Provide national standard for sustainable infrastructure
 Promote transformational approaches to sustainability
 Support transactional efficiencies and project delivery
 Demonstrate balancing of Triple Bottom Line
 Establish return on investment
 Scalable and broadly applicable
 Accommodate sector-specific rating systems
 Promote higher degrees of collaboration with third
parties involved in infrastructure planning and delivery
21
Sustainability - Rating System
 ENVISION - the nationally recognized standard for
sustainability performance
 Promotes transformational approaches with increased
project performance for triple bottom line
 ENVISION scalable and broadly applicable
 Accommodate sector-specific rating systems
 Adaptable to varying levels of sustainability applications
22
Rating System Implementation
 Institute for Sustainable Infrastructure (ISI) Formed
 Founding Partners - ASCE, APWA & ACEC
 ISI Board met February 8/9 2011 and will own and
administer the rating system with support from
Founding Partners
 ISI Core Products and Programs
 Rating System
 Communications
 Owner (A/E, agencies, practitioners …) interface
 Education and training for the rating system
 Support of assessors and verifiers
 Project recognition at various levels of performance
23
The Development Cycle
 All three founding partners committed to sustainability
and developed a number of tools and resource libraries
 APWA – Center for Sustainability
 ASCE – Committee on Sustainability
 ACEC – Green Scorecard
 ISI Formation
 Leveraging value of a consolidated approach
 Creating a framework that should become the National
standard for Sustainable Infrastructure
 Create a civil infrastructure standard model - USGBC
24
Goals for a Rating System
 Should become recognized as a National Standard for




Sustainable Achievement based on user acceptance and
application; accommodate sector-specific approaches
Should guide practitioners, owners, stakeholders in the
framing of infrastructure solutions and the performance
goals
Sustainability must be affordable
Public nature of infrastructure projects requires support of
policy makers, communities and stakeholders – guide
behavioral improvements in project conceptualizing while
confirming technical competence
Keep it simple, practical, adaptable and usable
25
Constructing the Rating System
 Should be relevant, supportive, usable and productive
 E-version, interactive, instructive, outcome-based, processsupportive, outputs
 Should be scalable according to complexity and size
 Stage 1 – checklist and self assessment
 Stage 2 – comprehensive consideration of multiple criteria
and core system
 Stage 3 – focused project assessment (+ operations, existing
facilities)
 Stage 4 – multi-attribute, complex, contested, TBL balancing
 Agencies, owners, consultants, communities (+/-) should
be able to use approach to reach consensus through
informed decision making
