Dear
colleagues:

We are processing a three-year study to create an
optimization framework for minimal building life cycle cost cooperating with
DOW Building Solution. We would like to invite you to participate in a survey
to understand the importance of life cycle optimization from a designer's point
of view. This survey is a significant input of the research. Your response
would be appreciated.

Those of you interested in this survey are very
welcome to reply us an email ()
before Oct. 15, 2012. We will provide you a link to the on-line survey. It will
just take you 5-10 minutes.

Thank you very much.
