这个设置似乎足够了吗？

在阅读的很多articles and comments here, I’ve been inspired to try and build Passive House insulation and air tightness.

I’ll share what I’m thinking so far with the hope that maybe you can direct me in any way. Not necessarily trying to get Passive House certified, but would like to build airtight anyway.

地区：田纳西州邓拉普的西山

Slab:
at or on grade: gravel, moisture barrier, 2″ or 3″ of EPS (only companies I know PermaR and ThermalStar), maybe 6″ to 12″ of sand (for thermal mass, inspired by the following link at 45:00 minutes:https://www.youtube.com/watch?v=AtHkvpRI6fc), wire mesh or re-bar, radiant floor heating pex, and poured concrete slab.
有人说将多水分膜放在沙子和EPS板上，但我认为这是不对的？？？

Walls:
2×4 16″ o.c. with sill seal and accoustic sealant under sole plate. Roxul R-15 rockwool/Mineral wool insulation in between studs with the ZIP (about $14 for a 4’x8′, but I don’t like that it’s OSB since plywood is much stronger) for sheathing and maybe Tyvek (sealed with tape as a secondary air barrier; belt and suspenders approach)
顶部有2.5英寸的EPS（insofast的R-10）或UX2.0（R8.5），EX2.5（R10）
total of 4.5″ of EPS (R18.5)
Also, maybe instead of the ZIP sheathing, using plywood with the Prosoco sealants.https://www.prosoco.com/product-use?term = exterior%20sheage
或将胶合板与stoguard密封胶和金色涂料一起使用
http://www.stocorp.com/air-moisture-barriers/

Attic ceiling: I’ve been thinking of sealing it off with ZIP (OSB) or plywood and ZIP tape (or StoGuard), putting Roxul R-15 rockwool/Mineral wool insulation between the truss bottom chord and then putting R-38 fiberglass batts on top of the plywood. I need an open attic so maybe an open energy truss (if that exists) but I don’t know if my design will allow for that. I have a large open center space that I don’t know how expensive it would be to get a beam that long. I’ll attach a floorplan.
Roof: I thought of just leaving it alone, maybe just adding a radiant barrier by atticfoil.com. Metal standing seam roof.

Heating and Hot Domestic water: wood cook stove (maybe a wood boiler so that I don’t have to fire the stove), solar water heater, and a Vaughn 119 gallon solar tank (http://www.vaughncorp.com/products/solar/#proddoc) all hooked up using natural thermosiphon. Radiant Floor Heating (will require an ECM pump).

Cooling: maybe an LG or Mitsubishi split ductless unit.

Windows：我不知道，但是我正在等待查看Klearwall在某些外壳窗口（计划安装它们。“ Innie”样式）上引用我的话。

Power: off-grid an 8kW Magnum system

水：目前正在寻找ECM型号的井

Ventilation: I’ve been considering and ERV by Zehnder or UltimateAir 200DX or a RenewAire EV90P

Price is the limiting factor, but maybe if I with a contractor friend of mine do the bulk of the work, maybe it will work. Interior of the house will be gypsum boards and wood and tile floors. Also, once I get the outside done maybe I can progress as funds are available.

Any help would be greatly appreciated,
埃德温

P.S. Does anyone know if this statements are true?
“普通聚乙烯薄膜可以在恶化relatively short time, even when sealed within a wall or buried under a concrete floor. “
“Tenoarm is resistant both to oxidation, the principal cause of polyethylene failure in walls, and to alkali attack, the principal cause of polyethylene failure under concrete slabs”http://conservationtechnology.com/building_films.html

如果您要构建被动屋标准，那么Phius Design工具将能够告诉您什么有效或无效。

http://www.phius.org/software-and-technical-resources

如果您要寻求净零能源（一个更实惠的目标）之类的东西，请参见本文档的表2 p.10：

http://buildingscience.com/file/5806/download?token=GouEIX9Y

请注意，这些是“整体组装R”值，所有热桥梁都被考虑。

根据您的确切位置，您要么位于区域4的温暖边缘或区域3的凉爽边缘。R20-R25全壁组件的一个示例（3区建议）为2x6 /R23岩羊毛，带有1.5英寸zip-r

If you're going to be off grid you'll get more heating efficiency out of an oil fired wall furnace than a diesel fired generator + mini-split. A better solution would be to use a small wood stove for heating, and the lowest input power mini-split size to be able to run during daylight hours with roof mounted PV, or just design the cooling load out of it and use a nighttime ventilation strategy (to the extent possible.)

以柴油燃料为代价，您可以在PV上获得相当不错的Paypack，这就是为什么在全球范围内的煤矿开采运营都在偏远的矿场安装PV，以运行大部分操作的功率。

Polyethylene deteriorates under direct UV light, but if you have UV light under you slab you have more serious problems than deteriorating PV! :-) Don't sweat that one too much- I've seen 40-50 year old 6 mil polyethylene pulled from walls that was still flexible & functional. If your nature is to worry, use EPDM (membrane roofing material.)

辐射屏障在没有管道的绝缘阁楼中是毫无用处的。设计阁楼的桁架和弦装载，以便能够处理〜18英寸的纤维素，以达到BSC文档中3-4区指示的R50-R60水平，您不必担心屋顶的增长。

无关，但是紫外线会损坏木材吗？

Given the existence proofs of 1000 year old unpainted stave buildings in Norway, wood can take the UV long enough for most purposes.

cool, the building is presumably older then the tree it came from lived

埃德温,
您的详细信息需要进行一些调整。

您不希望在平板下方的聚乙烯顶部沙子。那是一个很大的禁忌。有关此问题的更多信息，请参阅Polyethylene Under Concrete Slabs.

我已经离网居住了40年了，我不建议任何离网屋都包括空调。限制因素是必要的电池的大小，这些电池变得非常昂贵。通常，离网房屋用木炉或带有整个壁通风口的丙烷式空间加热器加热，并用吊扇冷却，或者（在干燥的气候下）沼泽冷却器。

I also don't recommend installing an HRV or an ERV if you live off-grid. It takes a lot of electricity to run this type of mechanical ventilation system, and you won't have much electricity during the winter.

也许只是我，但我无法遵循您对天花板绝缘计划的描述。什么是“阁楼天花板”？这意味着您的屋顶护套吗？还是在after子（在after子下）之后的倾斜天花板？还是很多人称之为阁楼地板？

Dana: I’ll consider myself zone 4, since up on the mountain it’s about 4° cooler than in the valley.

加热冬天：木炉做饭，加热家园和加热家用水（被动 - 热虹吸管）。
补充加热冬天：我将使用木炉使用一两件水夹克，如有必要，我将用水进行辐射加热。如果系统没有产生足够的热水，那么我将升级到气化木锅炉，并谨慎使用木炉。

夏季加热夏季：烹饪的电炉和一个太阳能热板加热家用水（被动 - 热虹吸管）。
补充加热夏季：带有水箱的电加热器的光伏阵列。

Cooling: mini-split

For my wall assembly I was looking at: drywall R0.45, 2x4 Rock wool R15, OSB R0.51, and 2.5” EPS R10 on the outside = R25.96 (will look at price to add 2” of Roxul R8 on top of the EPS)

天花板：石膏板R0.45，在天花板托架岩石R15之间，胶合板R0.62在天花板托梁的阁楼侧（每封关节密封）上带有R38玻璃纤维隔热材料的顶部（通风阁楼）= R54（R54需要6个）

密封产品：拉链系统护套和屋顶和/或祖母绿外套和/或Prosoco Cat 5

Slab: EPS ThermalStar X-Grade 2” R8.4 (everywhere) and a 4”-5” slab on grade. (will look at price to add 2” R8 -3” R12 of Roxul under EPS)

电力：48V 1576AH电池设置。Magnum 7.56kW PV阵列（顶部顶部），我可以在必要时“轻松”地建立到11.34kw。

Martin: Thanks for the article it gave me a lot of answers I’ve been looking for. I skip the sand, although I don’t know about putting the EPS under the Poly because I’m in a heave to very heavy region for termites (especially in the woods).

我想我会在夏天有足够的电源来获得ERV，如果我不在冬天，那么我只会在火上放更多的木头并破裂窗户。（这也将有助于产生更多的热水，从而使良好的辐射加热。）
