Recently, I covered a few houses for精美的房屋建筑我觉得这里也有一个位置。寻找对GBA读者发现有趣的问题的建筑师可能是一个挑战,因此,当我与他们建立联系时,我喜欢分享他们的见解,方法,材料选择和设计思维。记住将房屋视为整体系统的价值也是一件好事。因此,我们经常一次专注于一个方面。我喜欢想起我们在GBA聚在一起的原因;我们想建造适合居住在其中的人的智能,安全的房屋。以下是我认为适合该法案的三个项目。
火灾准备就绪和无毒
这座由太阳能的牧场房屋(如上图所示)位于加利福尼亚州索诺玛县的Wildland Urban界面(WUI)内,这意味着它必须符合所需的WUI WUI防火标准。屋顶必须不可抑制,壁板必须降低可燃性。“奇怪的是,木材仍然可以使用,但裸露的结构构件必须至少为4英寸。名义厚度,木壁板必须至少1英寸。名义厚度。”建筑师Bill Wolpert解释说,补充说,建筑方法必须包括封闭的拱腹。在这里,设计需要一个金属屋顶,并具有连续的岩盘绝缘材料和超厚的板和板壁板。
将机械,电气和管道系统放入10米的爬行空间中。添加了增强的蒸气延迟器,以防止水分检查。周围的通风口保持在最低限度;更少的通风口意味着燃烧余烬进入大会的机会更少。沃尔珀特说:“当燃烧的余烬被通风口吸入阁楼空间时,许多房屋大火开始。”“我们现在设计不需要通风的紧密阁楼空间。屋顶上的连续绝缘…

Great article, thanks for sharing these 3 stories here.
您(或任何看过类似的空气和蒸气膜改造的人)是否可以提供有关Jesper Kruse阁楼楼层工作的更多细节?在水平桁架组件的顶部添加空气和智能蒸气膜时是否有特定的内容?
This seems like it would be a great method for air and vapor management in a vented attic retrofit if one was doing exterior renovations primarily and wasn't inclined to remove a painted drywall ceiling in the room below. Then just blow the cellulose on top of the membrane?
也许这样做是很常见的 - 但是我在这里是新手,以前从未遇到过这个细节。我已经看到膜在桁架下方带来的膜。按照文章描述的方式进行操作将使我们的改造决策变得更加容易!
谢谢!

嗨,安德鲁,
Welcome to GBA! You are right to note this detail as atypical. In fact, just yesterday editor Brian Pontolilo was commenting on it. He was wondering about Jesper's motivation for taking this approach. I have an inquiry out to Jesper asking him to get into the weeds a bit. When I hear from him, I will share here what he tells me. Thanks for your interest. Stay tuned.
嗨,安德鲁
Thanks for your question, and Kiley, thanks for writing about my project.
Let me explain my motivation for doing things the way I did.
我们想达到被动房屋的气密水平(我认为我们达到0.45 ACH50)。由于Airleaks意味着失去能量,并且空气泄漏通常意味着水分以一种或另一种方式在您的组装中终止。
屋顶上的真正空气屏障是延伸和屋顶上的WRB(Mento Plus)。通过密封整个阁楼,而不是将气势屏障放在阁楼地板上,必须在必须精心贴上桁架的所有支撑物上,就可以轻松实现良好的气密数。
因此,阁楼地板上的膜的目的是试图防止尽可能多的温暖,潮湿的空气从天花板转移到阁楼上,但这不是我的主要空气屏障。而且,在我切掉胶合板的屋顶山顶上可以通过膜逸出多少湿度是有限制的,但是希望足够多的人能够逃脱以摆脱从温暖的房子内部渗入的水分。
Had I chosen to just run the Mento Plus over the roof as the air barrier, and not try to control moisture flow into the attic, I'm afraid I would have had moisture issues in my very airtight attic. But, who knows, maybe the hydroscopic properties of the cellulose would limit any serious trouble, I don't know, and I didn't want to find out the hard way.
Has I simply use the membrane on the attic floor as my air barrier I would have never hit 0.45ach50. There are just way to many seams where we had to tape around all the braces of the trusses.
And to go back to your question, having loose fill insulation on top off a vented attic floor would be susceptible to wind washing (is that what's its called when air penetrates your insulation layer, and lowers the actual R-value?) so that's also a consideration.
If you tore down your drywall ceilings to instal an air barrier in your ceiling you would still have all your interior walls to contend with.
You can watch a presentation I did on BS and Beer here, roof details are around 12.38

And I'm presenting just about this project at NESEA's conference on May7th at 3:30pm if you're interested in more details. You can also find info on our website mainepassivehouse.com
Hope this shameless self promotion is okay.
Jesper,
感谢您的详细说明。限制未通风阁楼下方房屋之间可能的空气运动很有意义,尤其是在安装峰值处的扩散通风。
幸运的是,纤维素甚至松散的纤维素都不会因通风阁楼的风洗而导致其R值的任何明显退化,因此这不必担心。
Jesper,
Thank you for the follow up comments and links to your presentation. The youtube video you linked to provided a ton of great detail. Not shameless promotion at all! Super helpful.
阁楼爬行空间地板上的智能膜对我来说更有意义。这似乎是提供更多蒸气管理而不进行室内肠道翻新的好方法。谁能想到这种方法要注意的缺点或陷阱?似乎是阁楼爬行空间翻新的不明智组件。除了棘手的磁带棘手之外...
作为新手,我必须查找扩散通风口。(GBA是如此丰富的信息!)
在较冷的气候中是否普遍接受扩散通风孔?从那时起,我从一段时间以beplay体育官方下载来发现了建筑科学公司的研究,而GBA更新。听起来像是扩散通风孔在温暖的气候中效果很好,并且在寒冷的气候中需要更多的研究。该工作有任何更新吗?
I'm in Zone 5, coastal Rhode Island. And Jesper's attic and roof detail would work great on a tricky section of roof I need to repair anyway.
感谢Jesper,Kiley和整个GBA社区!
