   1）i-stud上的内部护套通常是这种类型的壁系统的空气屏障，尽管拉链/胶带也应作为空气屏障效果很好。

   2）重复的热桥通过I-Studs大约是常规螺柱框架的一半。它仍然很重要，应该考虑到比标准框架（从热桥的角度来看）要好。

   3) Passive Houses have been built with these types of wall systems in Europe and in the U.S., though you'd be hard-pressed to meet the Passive House heating standard in Columbus, OH with the R-values mentioned on the Bensonwood site (R-35 walls / R-38 roof).

   任何具有绝缘材料的合理墙件组件都是潜在的Passivhaus设计的候选者。
   The are several variables that must integrate into a complete thermal envelope, with appropriate mechanical support included, to achieve Passivhaus standards. The Passivhaus approach requires a designer(s) to design and model the thermal envelope and mechanical systems in there entirety. There are site specific circumstances the must be factored into the model. Whether a design meets PassivHaus is dependent on building orientation and any shading elements near the building.

   R-35在温和的气候中可以足够的R值。该壁系统具有内部护套和外部护套的潜力，可以充当有效的空气屏障。墙壁组件田内的空气屏障是最简单的细节。必须对空气紧密度（和热桥接）进行审查的细节包括墙壁到地板细节以及墙壁到屋顶细节。Passivhaus标准要求建造的组件展示.6 ACH。
   窗户安装在工厂中的事实可能意味着总体设计将无法符合Passivhaus标准。必须仔细选择窗户和门，并将其安装到墙壁组件中是关键细节，尤其是在较冷的气候下。
   I wonder if anyone can comment from field experience on how well examples of pre-fab walls and modular construction have performed for blower door tests. On average do they seem to complicate achieving air-tightness or make it easier?

   我一直在想每次被动房屋都在讨论一件事。甚至接近PH标准的房屋比标准结构有所改善。

   And a Net plus home is even better than Passive House. And a house not built is even better still.

   And stretching the topic just a touch; when will the world catch up to the smarts of China and implement public policy to reduce population? I would think mandatory reduction in births is desired verses World War lll or world resource collapse.

   去被动房屋以及我们作为世界社区保持可持续性的任何其他方式。

   The Bensonwood OB plus wall has been developed to provide the next level of building systems in regards to thermal performance, combined with the effort to produce these building components off site. Our (Bensonwoods’)main goals are optimized structure, improved insulation, airtight enclosure and highest quality levels with tight tolerances.

   关于气密性问题，我们已经看到，与Huber拉链系统和欧洲垫片系统相结合的紧密公差是生产大型建筑物外壳（墙壁和屋顶）并快速组装的有效方法。从早期使用SIP到现在，我们已经看到不断提高BlowerDoor值。对我们项目的最新测试显示，如果正确且谨慎地应用，HUBER拉链系统的ACH50等级1. Huber邮政系统可用作可靠的空气行驶器。大约3年前，当我们开始使用ZIP时，我们的空气紧密评分变得更好。
   虽然我同意详细说明一个充满挑战的人，但我非常有信心使用该墙壁系统或其版本（根据房屋的位置，墙壁的某些方面可能会有所不同）可以达到该标准。实际上，我们将在今年夏天在VT中建造一所标准。
   为了获得认证，ACH50低于0.6是强制性的，必须实现。

   Installation and detailing of windows for a Passivehouse is a matter of how it is done, but not where it is done. Our experience is, that putting windows into the walls in the shop has many advantages and outweighs the concerns someone could come up with. It is a safe way to install and seal the window unit accurately and put it into place with the wall eliminating any challenges of handling these usually very heavy units (triple glazed with some times bulky euro frames) on a job site on pump jacks or aerial lifts.
   There is no difference in the final performance of a shop installed window compared with a site installed unit.

   我曾经在德国的家庭制造业工作。每天在欧洲产生许多认证的被动室。我和本森伍德有信心我们可以实现同样的成就。

   Thanks for the response, Hans.

   我对本森伍德所做的事情感到非常启发。您朝着增加技术和现代制造方法的使用方向发展，可能会导致该行业实现负担得起的群众住房的目标。

   I would like to learn more about the gaskets used to seal wall sections. Could you provide a link to a manufacturer or white paper describing their installation/use?

   I have seen more information come out about Bensonwood and I am taking notice. My first uncritical impression when I looked at their website was here is another production builder that may be overstating the quality of their product. I've been impressed by the additional information about their operations that have come out recently on this website.
   In my prior post in this thread when I noted a concern with windows installed in the factory I meant that I was assuming that Bensonwood, a production builder, would likely be using a "production" grade window (i.e. a cheaper window to keep costs down) and not a quality window unit that is essential to meet PassivHaus standards. I didn't mean that installing the window at the factory couldn't be executed well (I can see how my earlier post communicated this incorrectly).
   当我担任框架木匠时，我看到了许多糟糕的预制墙勃起的例子，所以我倾向于怀疑（对田间框架的怀旧），但听起来像Bensonwood是合法的，我希望能在未来的现场听到更多有关他们的现场的信息。在此网站上。

   Bensonwood (Ted Benson's operation in NH) has been producing high-quality timber frames for a long time, and they were one of the pioneers in foam panel enclosures. I lived for a while in Walpole NH and it seemed that every carpenter there at one time worked for Benson.

   但是它们产生了非常高端的房屋，他们的长期重点一直在质量上，无法负担性。他们的一个框架的成本不仅仅是我几年前建造的一个完整的超绝产品房屋。木材框架通常是昂贵的且通常效率低下的，因为它通常需要额外的框架或使用高英尺打印的泡沫面板来创建一个单独的热信封（尽管它可以用稻草包裹或涂抹）。

   有更好的技术来建造高效且负担得起的房屋，并且它们往往涉及更少，而不是更多的技术。

   本，

   Trelleborg is major Swedish manufacturer of EPDM building gaskets:http://www.trelleborg.com/upload/SealingProfiles/Catalogues/Standard%20products_EN_web.pdf

   Robert, (#7)
   We are not perfect, but we are also not stuck in our past. Your memories of our company might be relatively accurate because we have built many high end homes. That clients want us to work at that level is a tribute to our quality standards and our very talented team. However, we are not wholly defined by those "patron" types of projects. We also build many homes without timberframes and affordability is indeed a major company objective. We've recently completed an 1100 s.f. home for $150K, turnkey; and another at about 2200 s.f. for around $250K. There weren't a lot of timbers in those projects, but our quality standards weren't compromised.
   I would argue that the best quality standards come from knowing where to apply more technology and where less is better.
