-
Arc-Fault Circuit Interrupters (AFCI) are currently required in the bedrooms
of residential dwellings. Under this code, AFCI’s must be installed in other
areas of residential dwellings, which will cost approximately $75-100 for a
typical residential dwelling.
- Code amendments for lighting switches controlling lighting loads may result in
increased cost of approximately $50 per typical residential dwelling if these
types of switches are used.
Effective July 1, 2012, AFCI or GFCI will be required nearly everywhere in
residences.

I made a comment in January: BTW-
all of your standard exterior
envelope details are probably wrong… this refers to the fact
that all exterior walls surrounding heated spaces are to be covered with
continuous rigid insulation, as well as the required wall insulation:
In this example, I’d assume that a vaulted ceiling was being
installed, and that the rigid insulation continued up to the underside
of the roof sheathing in order to cover the insulation at the gable end
wall. If there was an unheated attic above first floor space, the rigid
wall insulation could stop at the plate line. Of course there would have
to be some sort of filler installed to avoid a change in
plane for the siding.
I’m showing the rigid roof insulation as stopping
just past the eave blocking and the wall sheathing at the gable end
wall. I wouldn’t recommend installing it this way unless filler was used
to make a level surface for the roofing. The point being that in
addition to wall and roof/ceiling insulation, there also must be a layer
of continuous rigid insulation to further trap energy within the
envelope. We won’t talk about moisture inside the envelope…

Another BTW: I would not consider the rigid insulation in this
photo to be continuous, in spite of what the contractor might say.
