Are the ductless minis that utilize a cassette unit vs a wall unit, less efficient?
Are there any drawbacks to a cassette unit over a wall mounted unit?
Lastly, can a cassette unit be mounted on a wall or is that not a good idea?

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.

We're building a pretty good green home in Gardnerville, NV, a place that gets 8" rain per year. We get cold in the winter (-10°) and are pretty warm in summer, about 10 days with >100° temps. Radon is an issue in our area. Our new home is being constructed with SIPs, therefore no attic space. We have natural gas at the site, pretty cheap in Northern NV. Our plan is forced air heating via Natural Gas in winter and a few days in summer when we'll use A/C.

I have a 1971Lancer double wide mobile home with hardboard exterior walls that seem to be toxic. I am sensitized to chemicals due to chronic pain and fatigue. The hardboard has a strong petrochemical aroma when the sun heats it; or when i open up the wall space, such as when working on an 120v wall box. I have been around all the other house components before (vinyl, paint, carpeting, MDF, etc) and have finally realized its the hardboard that is the main culprit.
