Innie/outie window operation

I am familiar with much of the conversation regarding thermal performance as it relates to innie/outie windows (http://lakesideca.info/blogs/dept/musings/innie-windows-or-...). My concern here relates more specifically to operation of innie/outie windows as well as "middies".

My concern is as follows:

It seems that "conventional" windows on regular houses are either double-hungs, sliders, single hungs, casements, or awnings, all of which swing outward or slide in one plane.

Manual D with slim ducted minisplit indoor unit?

In trying to use manual "D" to size the ducts for my ducted mini splits I've generated some questions.

To start out with what is the effective length where the air handler's output goes straight into the main trunk duct, there is no such example, the examples all show a change of direction, and I assume, with reservations, that the duct starts at the boundary between the air handler and the trunk duct?

Any recommendations on new house plans?

My family is in the process of our first new home build and I've been lurking on GBA for the last few months gathering as much information as I can. We recently got the first round of plans for our home and I was hoping that some of the experts here might be willing to take a look at them and provide suggestions for improvements. We're not going for anything like a Passivhaus but are definitely interested in green improvements that would improve the quality of living and/or offer a short to medium term payback.

Thanks in advance!

Layout for ducted minisplit?

My house's floor plan has too many partitions to depend on comfortable heat distribution with ductless so I'll take the slight efficiency hit to use duct ed distribution. The plan is to keep the ducts inside the "conditioned" envelope and very simple and all in the ceiling service cavity, both supply and return for the air handlers. My house is a rectangle with the long side running east to west. A central hallway divides the north and south areas. My proposed layout uses two air handlers, two zones, one "bedroom" zone on the east and a "daytime" zone on the west.

Hello,

First-time poster. In the past 2 months, I’ve read a hundred or so GBA articles and comment threads; I’ve been amazed by the expertise and generosity of the community. I’ve also read extensively at buildingscience and finehomebuilding -- I’m new to but very interested in building science. Here’s why:

CLT + Wood Fiber + Cork Facade

I have been through the ringer here with these walls and have circled back to what seems to inadvertently simulate an actual tree buildup.

(Heartwood --> Trunk --> Sap --> Cambium --> Bark --> EXT) is replaced by (INT --> Cross LAminated Timber --> Air Barrier --> Wood Fiber --> Cork --> Ext).

The roof assembly is a bit different, replacing the cork with an air gap (is this necessary?) plus sheathing and either TPO or EPDM.

Service cavity and other high performance dimensioning

OK... so now we're down to nuts and bolts here - drawing plans, permit set, etc.

I have never dimensioned rooms with service cavities... I'm guessing I should dimension to the service cavity, and just count it as part of the framing... any other quirks to dimensioning thick, high performance walls?
