About these predictions

This simulator uses a simplified thermal model based on FSEC and ORNL research. Actual attic temperatures depend on many factors including roof orientation, slope, thermal mass, cloud cover, wind, and air leakage. Treat these as educational estimates, not precise measurements. For accurate readings, measure with a $15-25 thermometer or get a professional energy audit.
