Underground housing, underground businesses, etc. Would that be better for the environment + possibly save on energy costs? Also possibly safer in certain scenarios like tornadoes etc.

Potential issues that immediately come to mind are ventilation, earthquakes, and flooding. But it's not like underground dwellings/basements/etc. aren't a thing, so maybe those issues have been addressed in ways I'm not familiar with.

Human internal clocks get advanced about an hour each day by exposure to light. Living in perpetual darkness (or under light bulbs only) wrecks hell on the system.

Plus you need some way to get rid of excess heat. Human society uses a lot of energy. That all turns into heat eventually.

    1. My graveyard-shift friend simply gets sunlight before going to work later.

    2. It's cold down there. Have you ever gone into a basement? That heat is useful.

    It's cold because it has a large thermal mass and nothing heating it up.

    Human civilization produces a lot of heat. The thermal mass means it might take years or decades to reach its heat equilibrium. But that equilibrium will be excruciatingly hot.
