Good luck on the commute tomorrow. Be sure to precondition the car in the AM about 15 minutes before you leave - I'm guessing you only have Level1 charging at home at this point so you will be limited on "ideal" preconditioning (the electric grid heater draws 6kw, but the L1 charger can only supply ~1.2KW) so you'll draw a decent chunk of power off the battery preconditioning, but something is better than nothing.
Once you get your L2 most people precondition in 2 steps - first precondition about 30 minutes before you plan to leave, finishes 10 minutes later - L2 will recoup most of the KW that were drawn off the battery in about 10-13 minutes, so then you precondition again about 10 minutes before you are ready to leave - this way you have a nice warm car, and a battery that's pretty much at 100% still as well.
In the summer AC draws a pittance of power compared to heat so L2 can supply all the required power for an AC cool down. Heck, I think even L1 will for that matter.
Looks like we are in for another cold snap starting in the early half of next week, so you may want to familiarize yourself with the ERDTT settings. If your commute is 60KM return you may want to adust it to the -4c range so that the car DOES use ERDTT for that sort of drive - the car will start the ICE a little to help with cabin heating vs just relying on grid heat alone. For short drives, crank it back down to the lower (I think -10C is an option on the second gen Volts) so that it doesn't waste gas for heat when you have a perfectly full battery. Lots of little things like this can maximize your efficiency.
