Why is my house colder inside than it is outside?

[aliveshecried]

This happens all the time.
I wake up and my house is freezing so i turn the heat up.
I walk outside expecting snow and it's 70 degrees.
My last apartment was the same way, anyone know the reasoning behind this?

If the sun is out its very conceivable that it would warm outside before it gets to you inside. You have protection against the elements if you're inside. When you open a window you'll let the warm air in and it can warm up the inside materials.

This is especially true if you live in a brick dwelling as bricks do not get warm on the inside very fast. A metal building warms up much quicker but this time of year you're more sensitive to the cold during this transition time. It has to get cold for two weeks before you get use to it.

I have seen that when walls are made of concrete and they are too thick, the entire building is freezing...

If the walls aren't thick, or made of concrete then i don't know...

It's you! :O
Wherever you go, everything around you gets cold. Hate to tell you this but, you might be a vampire

Because when I will come in your house cold will fly away... As I m outside hotness is outside.. ;)

Poor passive solar heating design.
