Im not sure if not having windows would actually do that or not, I mean, yes, they present an issue for insulation and let heat in during the summer, but those issues can be mitigated with good design on the part of the window glass itself, the placement of it, or structures around it like awnings, and they also do things like let light in that would otherwise need to be artificial, be opened to allow fresh air in during times when the outside is cooler than the inside, and allow for view of green spaces that helps with mental health and which otherwise would require more indoor space be made available to fit indoor plants to get the same benefit. I feel like having well designed and placed windows probably do more good than harm.
Windows are great, but they can not perform the same insulative properties as thermal bridge mitigating walls. A triple pane window has an R-value of 7-8, a typical wall without a thermal envelope and thermal bridging mitigation is R13-23. With anti-hermal bridging and thermal envelope a wall can get to R40 or higher.
If you want the most energy efficient home, it would have no windows and multiple doors as entry points.

Why multiple doors?
Insulation and preventing losses.
