In the end, I recommended not doing it because you won&rsquo;t save money and you may create some big problems for yourself, like freezing up the coil and killing your compressor.<\/p>\n<p>At the end of the article, I mentioned that zoned duct systems do close off registers, and that doing so can be OK with the right kind of equipment and design. But there&rsquo;s one thing often done in zoned duct systems that&rsquo;s rarely done well.<\/p>\n<p><a href=\"http:\/\/www.greenbuildingadvisor.com\/blogs\/dept\/building-science\/achilles-heel-zoned-duct-systems\" 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":[12652,4723,128,830,5581,12762],"class_list":["post-29694","post","type-post","status-publish","format-standard","hentry","category-green-building-posts","tag-air-flow","tag-duct-system","tag-energy-efficiency","tag-hvac","tag-pressure","tag-zoned-system"],"_links":{"self":[{"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/posts\/29694","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=29694"}],"version-history":[{"count":0,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/posts\/29694\/revisions"}],"wp:attachment":[{"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/media?parent=29694"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/categories?post=29694"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/tags?post=29694"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
