Can concur here in Western Europe. For more than a decade we've had a regulation where you have to run your plans for a new building through a tool that calculates a score reflecting the projected energy consumption in a broad sense. The maximum allowed score has been adjusted down every few years. The effect is indeed that all new buildings (and renovations that involve some kind of constructing new volumes) have improved massively in energy consumption. Still, we have such a massive amount of old buildings with next to none insulation that get renovated so slowly that it will take a long time to actually make a decent dent in reducing our climate footprint. But there's definitely a good focus on improving our buildings. Main issue with these new buildings is no longer having decent insulation to keep heating costs down but making sure they don't overheat when there's good weather, and ventilating them properly. This is also part of the score calculation but in my experience not sufficiently highlighted.
