Constant fans are sucking outside air into your house. Could be part of your Heat/AC efficiency problem mentioned in your post. A timer to run every 10th minute would be a simple improvement.

A lot of newer building codes require fans to be constantly running anyway due to the other part of the building codes requiring high r-value insulation.
Yeah that's a good point, I should turn off the fans for a day and see if it changes the power use...
Heat exchangers can ensure the incoming air is heated up by the air going out, at no cost.
We do have an ERV. But I suppose the cat fans don't actually exhaust through it. Maybe we could have arranged that had we thought harder about it before construction...
