AIA/CES
This program is registered with the AIA/CES for continuing education.
As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product.
Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.
Learning Objectives
Upon completion of this program, participants will be able to:
Identify some of the reasons why sustainability has become a hot topic of conversation;
Define sustainability as it applies to development and the roofing industry;
Identify the three critical elements of sustainable roofing;
Identify questions that should be asked of a manufacturer.
Politics of Sustainability
...each day brings further evidence that the ways we use energy strengthen our adversaries and threaten our planet...We will harness the sun and the winds and the soil to fuel our cars and run our factories...And to those nations like ours that enjoy relative plenty, we say we can no longer afford indifference to suffering outside our borders; nor can we consume the world’s resources without regard to effect. For the world has changed, and we must change with it.
- President Barack Obama, inauguration speech (20 January 2009)
Why Sustainable Buildings?
Today we are faced with many questions: Energy Supply
Reliance on foreign resources Economic growth worldwide
Rising Costs of Energy Peak Energy Demands Carbon Footprint
How big a role do Buildings play in this?
Why Sustainable Buildings?
LEED v. Non-LEED Buildings $11.33/sf higher rent 4.1% higher occupancy $171/sf higher sale price 25-30% less energy use

Sustainability Defined
Question: What is Sustainability in the Building Envelope
and Roofing industry? What is Sustainable Development? What is Sustainable Roofing?
Sustainability Defined
Most Common Definition
“Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
The Brundtland Report

Advertising Trying to Define Green Roofs? White Roofs? Black Roofs? Longevity? Recycled Content? Recyclability? Alternative Energy
Systems?
“Designing roof systems for future generations” Evolving concept Must address all aspects of the roofing process
and participants’ business Maximize waterproofing service life while
minimizing current and future resource usage Lowest life cycle cost available

Sustainable Productionpractice what they preach
ISO 14001 Certifies Manufacturer’s
Practices They ask owner’s to “buy in” to
the green program but do they?
Environmental Management Do they have policies and
procedures? Minimal Impact on the
Environment Can you quantify their impact
of production?
Sustainable Productionpractice what they preach

Sustainable Productionpractice what they preach
Recycled Content Leadership in Energy & Environmental Design
Materials & Resources Credit 4.1 - 4.2: Recycled Content 10%, 20% (30% for ID) Post-consumer + ½ Pre-
consumer Intent: Increase demand for building products that
incorporate recycled content materials, thereby reducing impacts
resulting from extraction and processing of virgin materials.
Sustainable Productionpractice what they preach
Raw Material Selection High Quality Bitumen + High Quality Polymers =
Positive Properties of Polymers High Percentage Phase Inversion On-site Laboratory Testing Throughout
Manufacturing Process Results
Increased Resistance to Heat & Ultraviolet Penetration Superior Cold Temperature Flexibility

minimal affect—if any—on construction costs if sustainability goals are discussed and integrated early in the design process.
