Forest Stewardship Council (FSC)
Today’s Focus is on the issue of
“Green Building” Materials

Customers are asking…
–
–
–

What makes a product “green”?
How do you evaluate “green”?
How do you find “green products”?
Manufacturers are asking…
–
How can we make our products “greener”?
What is “Green Building”?
It’s the practice of increasing the
efficiency with which buildings and their
construction sites use and harvest
energy, water and materials – or simply
the construction practices that
significantly reduce or eliminate the
negative impact of buildings on the
environment and occupants
Examples

Wal-Mart – Colorado
–
–
Store’s foundation made of ground-up
chunks of runway recycled from an airport
Used motor oil from the tire and lube shop
helps heat the store, as does old vegetable
oil from the deli
Examples

Flannery Const. Bldg – St. Paul, MN
–
–
–
–
Put in solar panels and added a white roof
to reflect sunlight and lower cooling costs
Installed recycled materials for insulation
Used nontoxic paints and cleaning supplies
to improve air quality
Built a sawtooth wall facing the interstate to
deflect freeway noise
The “Key” to the Movement



New set of standards that’s far more
demanding, environmentally speaking, than
local building codes
Invites innovation (based on performance
standards, not rules)
Now up to architects, builders and designers
to decide how best to reduce energy and
water consumption
Environmental Impact of Buildings*
–
65.2% of total U.S. electricity consumption 1
–
> 36% of total U.S. primary energy use 2
–
30% of total U.S. greenhouse gas emissions 3
–
136 million tons of construction and demolition waste in the U.S.
(approx. 2.8 lbs/person/day) 4
–
12% of potable water in the U.S. 5
–
40% (3 billion tons annually) of raw materials use globally 6
* Commercial and residential
What are the Advantages of a
“Green” Certified Building?

People want high aesthetic value in building but the building has to perform, too
–

Energy-efficient, nontoxic buildings that use less
water and provide a high level of indoor living
quality
Brings tremendous advantages
–
–
Minimum savings of 50% in energy use compared
to a conventional building
Water savings 50-60%
What are the Benefits of
“Green” Building?


–

Economic benefits
–

Improve the bottom line
Health and safety benefits
–

Reduce the impacts of natural resource
consumption
Enhance occupant comfort and health
Community benefits
–
Minimize strain on local infrastructures and
improve quality of life
What are the Economic Benefits of
“Green” Building?

Competitive first costs
–

Reduce operating costs
–


Lower utility costs significantly
Optimize life-cycle economic performance
Increase building valuation and ROI
–

Reduce HVAC loads and thereby reduce equipment size
Quantify financial benefit in terms of Return On Investment
(ROI) instead of payback time
Decrease vacancy, improve retention
–
Marketing advantages
What are the Productivity Benefits of
“Green” Building?

Improve occupant performance
–
–

Reduce absenteeism and turnover
–

Estimated $29 –168 billion in national productivity
losses per year
Student performance is better in daylit schools
Providing a healthy workplace improves
employee satisfaction
Increase retail sales with daylighting
–
Studies have shown ~40% improvement
How are buildings rated for
“Green”?


By using building rating systems
Competition between more than one
rating system
–
–
–
Drives improvements
Lowers costs
Benefits the ultimate consumer – our
shared environment
What is “LEED®”?
Leadership in Energy and
Environmental Design


USGBC’s green building
rating system that sets a
“national” benchmark for
high-performance “green
buildings”
LEED is used to certify
buildings and systems
What is “GBI”?
Green Building Initiative
•GBI was first to apply for and receive
accreditation as a standards developer under
ANSI (American National Standards Institute)
•“Green Globes™” rating system
What’s the difference?

LEED
–
–
–
Emphasizes its historical
leadership &
“consensus-based”
process for the
development of LEED
standards
Allocates more points to
the Materials section
Primarily allocates points
for achieving a certain
performance level

Green Globes
–
–
–
Emphasizes its ease-of
use & integration of
green principles and best
practices in every stage
of the process
Emphasizes Energy Use
above all other
categories
Awards a number of
points for implementing
certain strategies, as
well as for the outcomes
themselves

“Green” Concerns:
Do “green” homes look differently from
an average home?
 Are “green” homes more expensive?
 Will my home be filled with lots of new,
untested products and materials?


Patience….

Added costs of green building (long assumed to be
10-20% more than traditional construction) are falling
and may have been exaggerated

Building to certified standards today doesn’t cost a
penny more than conventional building

Hard-to-measure claims – ex: seeing better
productivity in work places where employees are
working in more natural light, radiant heat and highexchange air circulation (based on worker error rates)
What can City and County Governments
do to Encourage Green Building?

Incentives given to encourage green building
– Giving accelerated permitting to a green building
 Ex: Lowe’s store in Austin usually takes 15
months to get approvals
 Since is was LEED Gold, it took 3 months
– Density bonuses
 If you build LEED Gold, you can build 35 units
in your project rather than 25
 This incentive costs a city nothing

NFRC / ENERGY STAR®
Why are products certified?
• It’s important to customers
• Provides accurate and reliable information
• Provides building inspectors the ability to
confirm that the product meets local
energy code requirements
• Helps to compare products on a fair and
equal basis
Architects, builders and
consumers are challenged
by the many choices of
window/door products
available today
What is the best way to choose
windows and doors?
1. Look for the NFRC label
NFRC is a non-profit
organization whose
goal is to provide uniform,
accurate information about
the energy performance
of windows, doors and
skylights
2. Compare product
