Future Home Buyers Want GREEN!
• 63 percent of buyers are motivated by the lower
operating and maintenance costs that come with
energy and resource-efficient homes
• In 2007, the average U.S. home lost 5.7% of its
value, eco-friendly homes held their value,
appreciating in price
• Come sale time, a green property typically
appraises for 10% to 15% higher than
comparable conventional homes
• Demand for green housing has been growing —
46 percent of buyers would like a green home
but supplies are limited
• The market for green homes is expected to
boom from $7.4 billion to $38 billion by 2010
This is not about hugging
trees!

Why do we do it?
Yes Buildings consume:
•
•
•
•
•
•
40% of total energy
65% of total electricity
30% of raw materials
12% of potable water
Contaminants indoors can be two to
five times worse than those outdoors
Asthma increased in young children
by 160% since 1980
but,
Lets face it
If you can not sell it, it is worthless.

Factors in Choosing a Program
• What level of performance is desired?
• What shade of Green is desired?
• Do the measures deliver value to the
builder and new homeowner?
• Is the program clear, consistent, reliable,
and reproducible?
• Does the program provide market
viability and name recognition?

Recommendations
• Do ENERGY STAR as a standard
• Affordable home builders should consider
offering packages for IAQ, Water, Lighting and
advanced certifications
• Custom home builders should consider
specializing in an advance building practice (i.e.
ICF, SIP, etc.) and stick with a certification
program that fits their style
• Meet with a third party verifier to discuss your
project list to see what program is right for your
business plan
