GREEN BUILDING INITIATIVE™ FIRST GREEN BUILDING ORGANIZATION TO BECOME ANSI ACCREDITED NATIONAL STANDARDS DEVELOPER

-- Submits Application for Green Globes™ to Become an American National Standard –

Portland, Ore. (September 22, 2005) – Today, the American National Standards Institute (ANSI) formally recognized the Green Building Initiative™ as an accredited national standards developer — making the Green Building Initiative the first green building organization permitted to develop, maintain and withdraw American national standards.

On the heels of this announcement, the Green Building Initiative submitted an application to establish Green Globes™ — the first Web based environmental design and rating system for commercial buildings in the United States — as an American National Standard (ANS).

“ANSI accreditation demonstrates that the Green Building Initiative is committed to the ideals of openness, balance and consensus,” said Ward Hubbell, executive director of the non-profit Green Building Initiative. “We are happy to be recognized as an ANSI standards developer, but eager to proceed to the next step in this process by establishing Green Globes as an American National Standard. Doing so will take us one step closer to our goal of increasing adoption of green building practices among mainstream builders, architects and developers. As an American National Standard, Green Globes will help users integrate sustainable design principles into their buildings with the knowledge that the standard is backed by the best science and consensus-based development procedures.”

In accordance with ANSI requirements, the Green Building Initiative is now assembling a technical committee —which will include a balance of users, producers and interested third parties — to oversee the standard. The entire process of establishing Green Globes as a national standard is estimated to take up to two years. GBI’s ANSI-approved procedures will guide technical committee review, research, revision and voting on the standard, all in an effort to reach consensus on the final document. GBI will require the committee to accommodate input and objections from all stakeholders. Once finalized, ANSI will evaluate the evidence of consensus and the final standard may claim designation as an American National Standard.

Rating System ReportRating System Report

• More similarities than differences

• 80-85% point overlap between GG and LEED

• GG places greater emphasis on energy use and better integrates LCA

University of Minnesota recently completed a comparison study of Green Globes and LEED. Among their findings:

• Summit County MRF (Breckenridge, CO)• Blakely Hall (Issaquah, WA)

• Pfizer Clinical Research Unit (New Haven, CT)• RenewAire, LLC (Madison, WI)• Alberici Headquarters (St. Louis, MO)• WEEBF Office Building (Madison, WI) • Home Savings Bank (Madison, WI)• Clinton Library (Little Rock, AR)

About the Katherine K. Hanley About the Katherine K. Hanley Family ShelterFamily Shelter

First homeless shelter in the country to be recognized

by Green Globes

Awarded one Green Globe for merits in minimization

of energy and materials through efficient use of space,

the incorporation of an integrated approach and the

minimization of site disturbance.

”Green Globes was helpful due to its interactive

framework and stark functionality, and we found the

suggestions and solutions provided with the

questionnaires particularly insightful. Most

importantly, using Green Globes helped us and the

County in our focus of achieving sustainability.”

Why Green Globes?Why Green Globes?

• “I have begun to use both the LEED rating system and

the Green Globes program to dual validate our projects.

Why should there be only one entity validating our work

and telling us when good is good enough? I feel the

ability to use both systems provides our teams with the

means to thoroughly evaluate sustainable strategies for

our clients.”

LCA PioneerLCA Pioneer• First green organization to complete a practical

Life Cycle Assessment tool

– Will be integrated into Green Globes as part of our ANSI

process

• Authorized the free distribution of a generic version

of the tool to the larger green building community

Tool BackgroundTool Background• Created in partnership with Athena Institute,

University of Minnesota and Morrison-Hershfield

• Generic tool – ATHENA® EcoCalculator for

Assemblies is available at www.athenasmi.ca

Why LCA?Why LCA?• Asked to fight climate change by achieving

ambitious reduction targets for greenhouse gas

emissions

• Life cycle assessment (LCA) allows the impartial

comparison of building designs based on

measures such as global warming potential

– Fundamental shift from prescriptive methodology to

performance-based

Tool BasicsTool Basics• Provides instant LCA results for 400 common building assemblies

• Results embedded in the tool are based on detailed assessments

completed based on ATHENA’s widely-acclaimed datasets, as well

as data from the US Life Cycle Inventory Database

• Tool can be used for:

– New construction projects

– Retrofits

– Major renovations

– Industrial, institutional, office or residential designs

Tool BasicsTool Basics• Assemblies are broken down into six categories

– Exterior Walls

– Roofs

– Intermediate Floors

– Interior Windows

– Columns and Beams

• The number of assemblies in each category varies depending on

the possible number of combinations

– e.g. in exterior wall category there is eight basic wall types,

seven cladding types, three sheathing, five insulation and two

interior finishing options

Tool BasicsTool Basics• Design results are available in tabular form and show real

time changes as the inputs are adjusted

– Allows different assembly options to be considered in light of

their environmental impacts and provides the necessary data to

make informed decisions

Tool BasicsTool Basics• Results consider the following:

– Resource extraction and processing

– Product manufacturing

– On-site construction and assemblies

– All related transportation

– Maintenance and replacement cycles over an assumed

building service life

– Structural system demolition and transportation to landfill

Tool BasicsTool Basics• “Cradle to Grave” implications are then provided in

terms of:

– Embodied primary energy use

– Global warming potential

– Solid Waste Emissions

– Pollution to air

– Pollution for water

– Weighted resource use

• Results can be seen in summary tables and

graphs by assembly group

GBI GBI –– A Look Ahead…A Look Ahead…• Finalize ANSI technical committee work

• Integrate LCA Tool into Green Globes module and release tool for public use

• Green Globes Continual Improvement of Existing Buildings launch

GBI GBI –– A Look Ahead…A Look Ahead…• Creation of independent personnel

certification program for Green Globes

Third-party Verifiers (following ISO 17024)

• Support NAHB as they work to establish

their guidelines as an ANSI standard and as

an online version
