Why should vapor barriers be installed on the warm side of the insulation?

Because warm air can carry more moisture w/o causing condensation than cold air. If you had the moisture barrier at the cold side warm moist air would hit the cold surface and fall out as condensation, leaving water in the insulation.

What direction should the vapor barrier of insulation be installed?
towards the inside of the building
If you install Dow tuff R do you need to install tyvek?
Absolutely not. You tape the seams between panels to improve the vapor barrier characteristics of this product, but the foil faces of Tuff R (and any other polyisocyanurate insulation product) are your vapor barriers.
Do you put the vapor barrier of insulation on the inside or outside for an exterior wall application?
Inside, after the insullation, and wiring
If you are using a vapor barrier where is it installed when pouring for a slab?
between the finished grade and the concrete
What is the proper Attic Insulation vapor barrier orientation?
If you're installing insulation yourself, remember these guidelines when using a vapor barrier: * Always place the vapor barrier towards the warm side of the insulated area - facing downward on the attic floor or to the interior side of the wall. * When adding a second layer of insulation to an attic, do NOT add a second vapor barrier - this can trap moisture inside the first layer. Use loose-fill or unfaced batts or blankets; if only faced batts are available, cut facing every few inches to allow air to pass through. * If the vapor barrier tears during installation, tape it tightly. * If you have a crawlspace, add polyethylene vapor barrier on the floor of the area to reduce condensation from ground moisture.

Does the 2006 International Building Code require overlapping the flaps of rolled insulation when insulating exterior walls or can the insulation be stapled to the interior of the stud?
Insulation should only be stapled on the edge of the stud. That's what the flap on the edges is for. This creates a vapor barrier and if you compress the insulation enough to staple on the sides this reduces the insulation at that point. Insulation has to be fluffed to get the benefit. It is easier, quicker and does not interfere with the sheetrock in any way.
How can I become more green with my heating & cooling?
You can install a geothermal heating system which consists of a long pipe that pumps heat out of the ground during the winter or into the ground during the summer, Depending on your geography, you can also install vapor barriers with your insulation. Controlling moisture is critical for efficient climate control.
