Rawfiles is reset to "normal" exposure. Why?

Hello. I have a canon 40d and I work a lot with interiorshots. These shots are almost always overexposed deliberately on site. Some areas as windows are heavily overexposed as I want them to be, but when I load them into C1 4 they are as dark as they were if I had taken the image with no overexposure.

Today I shoot Raw + Jpg to see the difference, and as expected the Jpgs was much brighter than the Raw. Why don't C1 show my rawfiles as shot? It's really a lot of time wasted when I have to reset the exposure on every image. Can anyone help me out here? Is there any settings I can change To make C1 show my rawfiles as shot?
