--The minimum insulation recommendations are currently
*Ceilings have to now have a [[R value]] of 3866, not the previous 19*Wall's [[R value]] should be 1966, instead of the previous 11.*Floors should have a 11 32 [[R value]], instead of the previous 22.
Thermal Resistance = [[R value]]

* Location
-"Convective resistance depends strongly on the velocity of the air moving along the surface." All previous values are for areas with 10mph winds.
*"If the wind velocity increases to 15mph, the .2 R-Value of the 1/16" air film is decreased by 50%to .1, insignificant for walls, major for bare skin.
- ANSWERS TO SOLVING SUCH PROBLEMS
* Plant trees and shrubs near house to reduce wind effects.
