Membership is open to anyone in the HVAC&amp;R field; the organization has about 50,000 members.<br \/>\n<\/span> conference in Las Vegas. Actually, I&#8217;m doing one third of the whole presentation, which is titled <em>Flex Ducts, Hard Ducts and No Ducts: Migration Patterns for Duct Hunters (or not) in the Land of Thermal Comfort<\/em>. My part is on hard ducts.<\/p>\n<p>Chris VanRite is doing flex duct, and Robert Bean will cover the no-ducts part (which doesn&#8217;t refer to ductless minisplits but rather to hydronic distribution). We get 15 minutes each, so I&#8217;ll elaborate on my part a bit here.<\/p>\n<p><a href=\"http:\/\/www.greenbuildingadvisor.com\/articles\/dept\/building-science\/fundamentals-rigid-duct-design\" target=\"_blank\">read more<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[830,14355],"class_list":["post-256275","post","type-post","status-publish","format-standard","hentry","category-green-building-posts","tag-hvac","tag-rigid-duct"],"_links":{"self":[{"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/posts\/256275","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/comments?post=256275"}],"version-history":[{"count":0,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/posts\/256275\/revisions"}],"wp:attachment":[{"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/media?parent=256275"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/categories?post=256275"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/tags?post=256275"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
