Holistic Approach with Measurable Results

• Leverage full Agency input

• Fulfill design team’s strategies

• Incite contractor’s engagement

• Field Office follow through

• Innovative measurement methodology

THE NEED FOR A FRAMEWORK

There’s been significant focus on the sustainability of the built environment, but not in infrastructure, which covers larger areas and has wider, more variable impacts.

The lack of indicators and assessment methods to comprehensively measure the progress toward sustainable infrastructure has been a barrier to its development.

THE ENVISION RATING SYSTEM ™

Envision a Complete Approach

Purpose and goal

“The purpose of EnvisionTM is to initiate a systemic change…to transform the way infrastructure is designed, built, and operated.” -William Bertera

EnvisionTM is designed to be used as a project assessment tool and to provide guidance for sustainable infrastructure design.

Applies to all phases of infrastructure development.

HOW DOES IT WORK?

Levels of achievement:

1.Improved

2.Enhanced

3.Superior

4.Conserving

5.Restorative

HOW CAN EnvisionTM be used?

Envision™ can be used by infrastructure owners, designers, constructors and policy makers to:

Organize sustainability commitments into a comprehensive framework.

Meet sustainability goals.

Be publicly recognized for high levels of achievement in sustainability.

Make decisions about the investment of scarce resources.

Include community priorities in civil infrastructure projects.

PROJECT OVERVIEW

The PMLR will create a light rail alignment that travels 7.3 miles, connecting PSU in downtown Portland, inner Southeast Portland, Milwaukie and north Clackamas County.

MAX service is scheduled to begin in 2015.

The bridge will be highly versatile with tracks for light-rail and streetcar and allow for pedestrian and cyclists’ movement across the southern quadrants of the city.

TriMet Sustainability Drivers

Secure additional public support for projects and programs.

– How can TriMet leverage its sustainability commitment to garner additional funding from EPA/HUD/FTA Smart Communities grant program?

Help TriMet understand the significance of this project within larger transit industry.

Identify high-value sustainability initiatives that could be codified into best practices.

RFP Objectives

Help TriMet evaluate the effectiveness of its sustainability strategy

Identify additional opportunities for sustainable construction

Communicate the effectiveness of sustainability initiatives to internal and external stakeholders

Benefits of Our Approach and Envision

Provided guidance and tools to further improve the sustainability of the PMLR;

Will provide a baseline for future reporting and benchmarking by collecting and displaying sustainability metrics for the design and construction of the PMLR;

Will display the breadth and depth of TriMet’s commitment to sustainability in order to educate and hopefully inspire others outside of the agency; and

Will encourage an open and honest conversation about the challenges faced and solutions needed to move forward.

Positioned TriMet to receive additional funds from FHWA to apply INVEST.

Sustainability: Beyond the Triple Bottom Line?

Conventional sustainability frameworks seek to measure the ability to deliver economic performance, environmental excellence and social contribution.

Quadruple Bottom Line – Governance

Quintuple Bottom Line – Culture

How do you measure the effectiveness of sustainability strategies spanning these realms?

Envision helps you evaluate what matters,

and how much it matters. Scoring methodology combines qualitative and

quantitative assessment methods.

Qualitative approaches rely on:

• Explanation and description

• Dialogue, discussion and debate

• Iterative learning/double loop learning

Quantitative approaches rely on:

• Industry and agency-approved metrics for calculating measureable improvements, sometimes in relation to BAU.

“If we can come up with a set of metrics that people can agree to and that has the credibility … to measure and evaluate these projects, I think we’re going to have a very meaningful impact, a critically important impact, on preserving our environment.”

-Paul Zofnass, President, EFCG

Qualitative Assessment

Example: Turning building demolition into a training opportunity for local firefighters.

1. We crosswalk initiatives to the appropriate credit(s), which in this case is “LD1.3 Foster Collaboration and Teamwork.”

2. Using building demolition as a training opportunity shows a shift from BAU to a systems view of project design and delivery, helping TriMet earn a “Superior” Level of Achievement for this credit.

EPA created the Waste

Reduction Model (WARM) to

help solid waste planners and

organizations track and

voluntarily report greenhouse

gas (GHG) emissions reductions

from several different waste

management practices.

Kilowatt Hours (kWh) of

Electricity Saved, Tons of

Emissions Avoided, Tons of

Waste Beneficially Reused,

Gallons of Gasoline Saved,

and more.

WARM allows users to compare baseline

scenarios of material consumption with

alternative, more sustainable scenarios. The

JLA team could populate material recovered

(tons) from buildings using data collected by

Stacy and Witbeck.

"During construction, the

PMLR team salvaged X

tons of building materials

for beneficial re-use. This

has the same impact on

the climate as planning X

number of trees."

Several, including

avoided, and number

motorized transport

users.

The Transportation Research

Board has published data on how

bicycle access affects ridership.

Using this data as a baseline, the

JLA project team could apply a

framework for evaluating non-

motorized transportation

benefits and costs developed the

Victoria Transport Policy

Institute in British Columbia.

The "Units" of measurement

could be as diverse as the

categories of non-motorized

transport benefits and costs,

which include "Improved

walking and cycling

conditions ", "Increased

walking and cycling activity",

"Reduced automobile travel",

"Land Use Impacts",

"Economic Development",

and "Cost".

In the category of Reduced Automobile

Travel, examples of meaningful metrics

include congestion reduction, road and

parking facility cost savings, consumer

savings, accident reductions, energy

conservation and air emissions reductions.

"The PMLR makes it

possible for X number of

people a year to use their

bikes and public transit to

get to work. This amounts

to a savings of X gallons of

gasoline each year."

Positions agencies to secure additional public support.

Encourages efficiencies.

Infrastructure specific.

Objective framework allows you to clearly measure whether sustainability objectives are met.
