Power outage and mold
I was discussing with a friend who is also engaged in planning his house build and a couple of questions came up as I mentioned the building science lessons I am learning.
我们在我们的地区有非常重要的模具问题（混合潮湿，4A区，纳什维尔以西，TN）。
建立紧身房屋是否增加了模具的风险中的延长的停电？周。
单独的问题：如果建造一个拍摄网格之家（思考Ammish），没有能力的屋子将是一个紧身的房子是模具促销的灾难？如果是的话，最好的建筑材料和方法是什么？
谢谢你。

我不确定为什么断电会影响模具的增长。紧身房屋将抵抗两个方向，进出的气流。如果您有扩展的停电，由于更好的空气密封，紧身房屋中的条件可能会比在较小的房屋内更换。
If you build everything correctly to limit moisture buildup you should be ok regarding mold regardless of if you have electric service or not. Remember that there are plenty of unconditioned sheds that don’t have mold problems.

谢谢比尔。
My thought was that people living in a house will have humidity coming from them, drinking water, taking bath, heating water, etc... Whereas a shed would not face these and are typically very leaky, at least in my limited experience.
I suspect that if you have a long enough power outage for moisture levels to rise to problem levels, you’d probably not have hot water, or even water at all. As others have said, cracking a window will provide plenty of ventilation to keep moisture levels under control.
作为副书，我的常规工作正在为关键设施设计和咨询，主要是在电信行业。由于所有花哨的电子设备，我们保持了非常复杂的环境控制系统。无论如何，备用电源是非常认真的，因为没有功率=没有商业，我们有监管可靠性标准。我们的燃油供应标准是满载的48小时运行时。这是业内相当普遍的标准。
My point is that if you’re worried about humidity during a major disaster-level outage, don’t. There will be far, far bigger issues with a 48+ hour large-scale power issue (loss of refrigeration for food, loss of sanitation for water/sewer, etc). The off-grid people will really be feeling luxurious! You’ll lose pretty much all utilities, water included, so you’ll be in survival mode and humidity buildup will be less, and not something you’ll be worried about.
对于较小的（邻域）但漫长的中断，获得一个好的发电机并保持保持。由于可靠性问题，我将远离共同品牌的盒子店随身携带。

Bill,
Good analysis and perspective on the real issues on one's plate with an extended power outage. I was just wondering if all these well built houses would become greenhouses in an extended situation; but, alas we will have bigger fish to fry than mold in such a situation.
As for a tight building being the best idea for a permanently off grid house, it is not registering (greenhouse). I am not going this route (off grid); however, a few folks I know are into that and I wondered how it would work for them?
Thank you gentlemen for your imput.

Tight houses are more energy efficient, other things being equal. Off grid houses tend to have limited energy resources available, so maximizing efficiency is good. On grid houses pay for energy they use, so efficiency is good. On grid houses with power outages running on backup generators are limited on fuel or generator capacity so efficiency is good.
On grid houses without backup power during power outages want to maintain heat inside for as long as possible. Tight houses will help to do this.
Any way you look at it, building a tight house helps you. I’d always recommend building as tight as you can, and insulating as well as you can (within reason :). You’ll save energy and money in the long run regardless of where your energy comes from. I always advocate for efficiency, and it’s one area where there really is no downside. If your house gets too hot, open a window or two. Easy.

麦克风，
Tight houses need ventilation. If they can't have it supplied mechanically, because there is no power to do so, they need to have it supplied passively by opening windows. One way or another there needs to be a mechanism to remove both humid air and contaminants.
The same moisture sources with less ventilation = higher interior humidity. But tight building is still a good idea. If you rely on leaks, then ventilation is often too much or too little - depending on wind. If you use a window, you can make it exactly what is needed (for humidity and indoor air quality).
麦克风，
People lived without electricity for hundreds of years, and most homes weren't overwhelmed by mold.
在冬天，大多数人保持窗户关闭。他们通常不会有模具问题，因为冬季空气持有很小的水分。冬季空气是干燥的空气。
在空调发明之前，在田纳西州的夏天，当室外空气炎热而潮湿时，大多数人都敞开了窗户。房屋内的湿度条件与户外湿度条件相同。除了大多数人手中的柠檬水玻璃杯外，没有任何冷表面。
谢谢马丁。我以为我们的日子的更严格的信封做了一些差异。因此，湿度触摸冷却表面，使其恢复露水，水状态和生长。因此，紧身房屋上的一个开放窗口与两百岁的日志小屋上的开放窗口相同。我没有完全ggrasp整个概念，但我现在很满意。谢谢你。
