For the Passive Buildings Canada AGM we had Danny Harvey from U of T
and Ryan Daglish from CUFCA speak on both sides of the topic, at
least as it pertains to global warming potential of blowing agents.
Harvey's presentation had the most recent data available (compared
to the EBN and articles that relied on his earlier work)<br>

I am trying to research the environmental impacts of the
production of EPS and XPS foam insulations. Obviously, this
industry is on the defensive, because all I can find are
industry-sponsored glossy brochures touting the complete
benevolence of foam insulations and industry-sponsored tests that
give me a bunch of numbers I can't understand, no comparisons of
those numbers to other materials and a "see, it's all good"
conclusion.
<br>
<br>
Environmental Building News has had some articles that have been
helpful. Any other suggestions?
