Actually it is. Wind contributes to additional heat loss from your house in 2 ways.
#1 Forced convection vs. natural convection. If the frigid air is blowing across your walls harder/faster it takes away the heat faster.
#2 Air infiltration: with higher winds you get higher pressure differentials. That higher pressure leads to more cold air infiltration into your home; when cold air comes in, warm air must go out, contributing to heat-loss.
If you want more details/explanation of either one of those I can go into more details. I may even get into nerdy, engineering, heat-transfer stuff.

Finally, an explanation I can understand!
LLigetfa said:I knew after I said it that I'd get arguments. What I should have said, is "Wind Chill Factor" is not a factor. -40 to my radiator antifreeze is still -40 at 100 MPH. The outside temperature indicator on the dash doesn't change with how fast I drive.
The "Wind Chill Factor" on human skin though is very real. The effect of wind against a leaky building is obvious too.
Also, the heat index WRT to humidity usually bottoms out with the cold. After the temps drop significantly, the RH becomes 100% so dropping it further doesn't affect the index since you'll still be at 100% RH. Now if there is a North wind bringing down a mass of Arctic air, it may had been colder and some of the humidity extracted. That's how I get that good drying of my wood in Winter, cold dry wind.
