We don't need styles, movement or whatever, we need forms evolved for a long time by normal humans (on this point I'm a fan of Christopher Alexander position on architecture, see A Pattern Language or The Timeless Way of Building). Modern architecture is just a fraud based on nothing.

I don't think this is true. Some of the most energy efficient houses are passive solar houses that use large glass surfaces for heating that are covered using shades in the heat, but also use high thermal mass materials for heat/cold storage.
From an aesthetics perspective, many people like natural light, I wouldn't want to live in the houses you provided as examples for that reason.
