How should we deal with Private Rooms?

1. Don't worry about it
2. Seek clients who are not too concerned about comfort
3. Keep bedroom doors open (especially when occupied)
4. Provide Radiant Panels and Don't worry about Cooling
5. Preheat the Ventilation Air and Don't worry about Cooling
6. Undercut the door and pray
7. Provide a Ductless in every Private room instead of the Common Space(s)
8. Provide Transfer Fans between Public and Private Rooms
9. Don't Do Ductless
10. Other

I have a 4' deep stem wall with a independent concrete slab floor. I have a 2" XPS foam thermal break around the entire slab edge except for at door openings where the frost wall was dropped to accommodate a thicker slab.

I want to add an exterior thermal break at the door opening locations. How far past the door openings should I run the thermal break in order to prevent heat loss from "sneaking past"?

I have a 4/12 roof that is being converted to an unvented attic. The foam subcontractor assured me that he could get foam, being sprayed on the underside of the roof, to the plate line. He finished the job assuring me that they had been successful.

I drilled holes and used a scope to see the void that extends out to 6 -10" from the exterior wall plates. How much of an issue is this?

All,

I'm a licensed GC designing an addition to my personal residence which we built in the late 80s. The original house was built with 2x6 studs and might very well have been the first house built in NC with a sealed crawl space. (I gave my building inspector a copy of a sealed crawl space article by the TVA, and he OK'd the sealed crawl space.)

I would greatly appreciate some input on a couple aspects of the design.

Thanks,

Bill

My husband and I are considering a home on a huge lot we love, but we found out it is a solar envelope home built in 1983. I've read mixed reviews on this type of home and we have some concerns. We'd appreciate any help!

1. If we wanted to ever convert it to a normal home, is that possible?

2. Have people really experienced health issues stemming from mold and modes growing in the walls and under the house from the moisture in the air? How common is that? Fires seem to be a concern too.

3. This home is in southwestern Illinois. Will it really make a big difference in our bills?

I am replacing a 30 year old plastic bubble skylight as part of a major remodel. The skylight is located a flat (low slope) roof in a typical Chicago small residential building and serves a third floor bathroom. The skylight will not be openable.

I have searched this site, the web, and the manufacturer's installation information, but am still unsure how to orient the skylight to maximize its benefits, while reducing drawbacks, like unwanted heat in Summer. It appears that the only requirement is that the skylight be installed at a slope greater than 15 degrees.

I am renovating my house, installing solar panels and getting rid of my gas forced hot air system and replacing with mini-splits (very small home < 1000 sq feet)
I would like to install an energy efficient heating system in the bathroom (about 6' x 8') as I'm not sure the heat will effectively get there, plus I like to have a separate zone for the bath for the usual reasons. i had thought about electric radiant heat in the floor but have heard that can be quite an energy drain.
Do people have a suggestion for a very small heating unit for this purpose?
Thanks!

I have a recurring question / situation that comes up in my east central MN location (6b-7a border). There are many 1970's homes undergoing remodeling and looking to add insulation for improved comfort and energy effciency. Miost common construction is drywall, kraft faced R13, 2x4 walls, 3/4" Bildrite (asphalt fiberboard sheathing).

Hey folks, been reading the site for a while during our planning process and its time to start asking some questions.

We are finishing a space above our garage, about 26 x 26', to make a studio, and are trying to keep costs down and still insulate it well. Is the difference in price between the two types justified in improved insulating quality over time or is the actual insulation pretty comparable? The cellulose people are adamant about their product, and the fiberglass people say the difference is negligible. And then how much more/less green are the two? Thank you!
