   处罚
   "According to Schmidt's Passivhaus consultant, this configuration brings with it some energy penalties and results in the need for additional insulation." Please elaborate on these penalties.

   对黛布拉·格劳兹（Debra Glauz）求助
   Debra,
   The energy penalty is increased heat flow through the building envelope (floors, walls, and roof).

   这种能量惩罚的原因是伸展的形状，而不是紧凑的形状。

   越近，可以实现紧凑的形状（例如，立方体），热性能越好。凸起，ELL和悬臂地板是一个问题，因为它们增加了表面体积的比率。

   That's the issue that Tom Schmidt was referring to when he wrote, "We designed it to have living space over the garage. My understanding from the Passive House consultant is that based on how Passive House calculates everything, you are penalized by having a tuck-under like we do."

   penalty
   Thank you. I understand efficient shapes. I was just making sure there wasn't some obscure penalty for parking a car underneath a living space.
   Sounds like surface/floor ratio is high so super insulating the garage ceiling, along with super insulating walls and ceiling for the living space over garage is not going to get the job done.

   没有成本效益，但有趣...
   当人们谈论最小化表面积并使用真空面板时，就会想到“但是它仅适用于真空中的球形鸡”。是的，这是极端的，但是如果有人真的想做这个令人印象深刻的隔热水平，而不是在Cape Cod租用一个不错的海岸房屋，请判断谁？而且我们经常从极端的原则中学习，所以请吧！

   trade offs?
   使用疯狂的墙壁结构，我认为这种增量量的R的成本会很高...我认为Windows之类的东西更容易升级？还是更好的呼吸机？ETC？

   或者其他盘调整?

   Also it seems odd that someone would be so gung ho to be "certified" yet purposely make the house inefficiently laid out? Also seems odd that a few extra wall surfaces (buffered from outdoor conditions by garage walls/door) would cause this dramatic of an increase in needed R... (especially since the garage is likely at least somewhat insulated, (since its a mcmansion...))

   有点像买一个prius以友好友好...但是然后将其停在车库里，每天开车去上班.....： - /

   我同意这更便宜
   我同意这更便宜PV than add all the R value for a trophy but if that's what the customer wants you build it for him. I would rather see thicker sip panels than stud walls with blow in as it still settles gravity always wins. There are a number of those built in northern MN and an infrared drive by shows that after a couple years they all settle. I wonder if they thought of a sip floor over the garage to separate the spaces.

   定居？
   唐·J（Don J）：“有许多在北部北部建造的，并通过显示几年后的红外线驱动器。”据我所知，纤维素比自然沉降密度更密集（1.75至2个PCF？）不会沉降。此外，如果它确实安顿下来并且墙壁的包装与盖子连续，那没关系。您只需要在盖子的周围吹更多一点即可。也就是说，在窗户下安顿下来将是有问题的，因此请打包好。

   等一下？
   Hmmmm. When I plug in one of our Certified, foam free (except for sub slab and window install, the two area's that I believe should be vapor closed) cellulose filled projects, in Minn, MN. The AHD stays exactly the same. The Peak load stays the same. The primary energy demand (source energy) rises slightly. From say 99 kWh/M2a to 102 kWh/M2a. Still well within PH standards.

   我认为这80件东西与PH无关，与设计/计划/咨询有关。

   If you want to trade R80 walls for ineffective geometry,insolation,poor glazing specs/ cheap doors whatever. That is fine. Dont have a discussion about PH. These are design issue's. Not PH issues.

   阿拉斯加费尔班克斯（Fairbanks Alaska）拥有14000多名HDD，明尼阿波利斯（Minneapolis）约为7500hdd。贝尔法斯特我。7500hdd

   除非您想要一个如何在费尔班克斯建造出色的房子，否则我不会看Thorstons的偏远墙。14000 HDD气候在极端的时间内保持光线和黑暗。

   MN中的R80？是的，在屋顶上。然后还有一些。
