Information about "Best Available Technology" reduced-nitrogen septic systems

I'm building in Maryland, where the state just passed a law requiring homeowners to install "Best Availalble Technology" septic systems. The State has approved a few models - Singulair TNT, Hoot BNR, Advantex and a few others. Because these technologies don't seem to be widely used and they're kind of new (which concerns me), I'm having a hard time finding objective informaiton about which one to choose.

Does anyone know of a source for good unbiased information or comparisons on these types of septic systems?

Is there a building code on deck board spacing?

I have a flat roof and my contractor built a cedar board floating deck. the area is 16'x20' range and he made into 4 section, 16'x5' each. the boards are tight fit(no space) and also tight fit to the edge wood board( the wood board sit on top is metal capping). the nails are all sunken under the wood surface. One winter with snow/rain, I had to shelve the snow off the roof since the ice/water sit on the cedar boards. there was a leak(this roof did not have leak before the new deck). I tried to find out where the leak was, but the boards were all frozen together, like a big ice block.

Housewrap alternative?

Building just outside of Memphis, TN - the home is all brick with OSB sheathing. The builder doesn't think housewrap is necessary- when they spray paint the soffit and fascia, they also spray the OSB (not thick, not full coverage, but a thin breathable mist)- does this produce the same benefits as house wrap?

Secondly- using vinyl windows, they do not spray foam aroound them as they say if the window gets moved during construction they cannot adjust the fit once it's been foamed. True or BS?

Suitability of Rainscreen Wall Design

I am working on a wall design for a small house that we are going to construct this summer in Oklahoma. My planned wall from the inside out goes as follows:

1. 1/2" gypsum
2. 2x6 stud framing, 24" O.C.
3. Cellulose insulation in the cavity
4. 1/2" plywood
5. 1" XPS
6. 30 # felt
7. 2x4 vertical furring strips attached to FastenMaster specs (3/4" material seems inadequate for siding fasteners)

Sherwin Williams has a paint product that is sprayed or rolled on the underside of the roof deck that acts as a radiant barrier

Does this product work? Or should I use the "bubble wrap" stuff?

Geothermal house air supply

I am trying to re-route my household fresh air intake to run under the ground and enter near the basement floor in order to warm it up in the winter and cool it down in the summer. I live in Wisconsin. I presently bring fresh air into the house constantly and route it to my furnace cold air return. For underground routing, I am concerned about radon gas and water getting into the tubing. I am also concerned about contamination of the air from the tubing.
Thank you,
Dennis Vogt

3. Installed Roxul r15

Using Roxul in floor joists... dealing with pipes, wires, etc.

Hello, all...

I'm planning on installing Roxul Comfortbatt insulation into the floor joists of my CT home (the floor above an unconditioned basement).

Unfortunately, there are a lot of pipes, wires, conduits, etc. that are within the joists in some areas, and I was wondering if there are any tips on installing Roxul when things are "in the way".

I did search for tips here and elsewhere, but only came up with fiberglass techniques, which seems to be "stuff it in there".
