I don't write often, but I "listen" a lot and speak up as my schedule allows. </div><div><br></div><div>And secondly, I was asked to share this by several of you. I was recently hired by a client to appeal a straw bale code in Grand County, UT that required a "weather barrier" or "sheet barrier" 32" up the exterior of the straw bale wall under the plaster. This code requirement has been in place for over 10 years, previously required a full sheet barrier and was unsatisfactory to many builders and owners in the jurisdiction. The client, who I applaud, was willing to put some resources into having a study of this and to create a hopefully successful appeal for the benefit of those following him. The head code official is on the board of the International Code Council and is involved at the state level as well. Thanks<font class="Apple-style-span" face="Arial, Helvetica, sans-serif"> go </font>to several folks on this list who I contacted individually for thoughts and data related to this issue. I collected data from the StrawSense systems that GreenWeaver makes and sells and wrote a report summarizing that data, the data in a study by Kris Dick, and a one-time moisture investigation I did of the Waldorf School campus in 2007. With that in hand, I met with the building official, the clients and their builder last week and at the end of a two hour meeting, he agreed to remove the requirement from the code and to look more deeply at the other straw bale requirements and opportunities<font class="Apple-style-span" face="Arial, Helvetica, sans-serif"> to improve their code.</font> The meeting helped me to see again some of the common misconceptions about drainage vs. storage wall assemblies, the role of plasters, and the properties of vapor permeance and capillary absorption. But, it also helped me to understand again the value of taking the educational approach, going in with an appreciation of the motivations for a code, and an attitude of wanting to work together. The building official was very conscientious and I applaud him as well in this change. </div><div><br></div><div>Thanks again to those involved. </div><div><br></div><div>Laura </div><div><br></div>I will make available a .pdf of the data after I add some additional data that came in after the fact. </span><br><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 18px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 18px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div class="MsoNormal"><font class="Apple-style-span" color="#4C721D" face="'Times New Roman'" size="4"><span class="Apple-style-span" style="font-size: 16px; "><b><i><span style="font-size: 12pt; font-family: 'Times New Roman'; "><br class="Apple-interchange-newline"><br><br></span></i></b></span></font></div><div class="MsoNormal"><font class="Apple-style-span" color="#4C721D" face="'Times New Roman'" size="4"><span class="Apple-style-span" style="font-size: 16px; "><b><i><br></i></b></span></font></div><div class="MsoNormal"><font class="Apple-style-span" color="#50742B"><font class="Apple-style-span" face="ArnoPro-SmbdCaption"><font class="Apple-style-span" size="4"><span class="Apple-style-span" style="font-size: 14px; ">Laura Bartels</span></font></font></font></div><span><font class="Apple-style-span" color="#50742B"><font class="Apple-style-span" face="ArnoPro-SmbdItalic"><i><font class="Apple-style-span" face="ArnoPro-SmbdCaption"><span class="Apple-style-span" style="font-style: normal; "><font class="Apple-style-span" size="4"><span class="Apple-style-span" style="font-size: 14px; ">P.O.
