I doubt Houston suburbs will ever replicate a European walkable city. Europe had a heatwave recently and thousands died. Houston deals with that sort of temperature every summer. Then there's the humidity.

Meanwhile business offices in Houston continue to be aggressively air-conditioned, filled with people wearing full suits and ties, in blind imitation of European culture.

That's rather missing the point.

People die in european heatwaves because they're not used to the heat and don't have the right habits, and the homes are not set up to handle them: AC is relatively rare (especially whole-house AC), homes are not set up for airflow, and almost none have ceiling fans. Unshaded southern / south-western windows are also rather common, as usually the goal has been to get the sun and heat in, not keep them out (in fact in the last few decades the building codes have drastically increased the required window surface).

Which of course doesn't mean you should follow a central or northern european set up for a city like Houston, you should rather look at southern-europe, or SEA. But overall it's probably going to look like favouring shade, greenery, and airflow.
