That blog I linked to is great; it's written by the principal of an HVAC design firm who is well respected.

Green Building Advisor (https://www.greenbuildingadvisor.com) is a great community for such things, with a 99% residential focus.

I have an ERV in my house, running continuously. There are some great pieces of equipment out there, but they require conscious consumers and/or progressive code enforcement to end up in use.
