This was a one-day conference largely coordinated through the local chapter of the National Association of the Remodeling Industry (NARI). There were two rooms of exhibits by manufacturers and suppliers for products ranging from architectural salvage and materials, to home power generation systems, to lighting and plumbing manufacturers, all emphasizing green solutions for building and remodeling. <br /><br />The keynote address was by David Johnston, a former remodeling contractor, who is now a consultant and author (<a href="http://www.amazon.com/gp/redirect.html?ie=UTF8&amp;location=http%3A%2F%2Fwww.amazon.com%2FGreen-Remodeling-Changing-World-Room%2Fdp%2F0865714983%3Fie%3DUTF8%26s%3Dbooks%26qid%3D1174317245%26sr%3D8-2&amp;tag=greeopti-20&amp;linkCode=ur2&amp;camp=1789&amp;creative=9325">Green Remodeling : Changing the World One Room at a Time</a><img src="http://www.assoc-amazon.com/e/ir?t=greeopti-20&amp;l=ur2&amp;o=1" border="0" width="1" height="1" /> and <a href="http://www.amazon.com/gp/redirect.html?ie=UTF8&amp;location=http%3A%2F%2Fwww.amazon.com%2FBuilding-Green-Black-White-World%2Fdp%2F0867185074%3Fie%3DUTF8%26s%3Dbooks%26qid%3D1174317593%26sr%3D8-1&amp;tag=greeopti-20&amp;linkCode=ur2&amp;camp=1789&amp;creative=9325">Building Green in a Black and White World</a><img src="http://www.assoc-amazon.com/e/ir?t=greeopti-20&amp;l=ur2&amp;o=1" border="0" width="1" height="1" />)who spoke about climate issues and about why building greener buildings matters. Johnston prefers the term &quot;Global Climate Change&quot; to &quot;Global Warming&quot; because the effects will be more complex and catastrophic than mere warming. &quot;Global Warming&quot; will actually make for a colder Europe, with the Gulf Stream diverted further south by a gradually warming polar cap. In addition to talking about why greener buildings are important, he also spoke extensively about how to make better, greener buildings. </p><p></p>
