I have seen changes in recent years in the Architectural industry when it comes to things like electric parking bays, higher spec glazing/insulation, etc but one of the main issues is how they are adopted by clients. Typically with each project, there will be a requirement for specific sustainable elements (ie X amount of electric bays per size of the footprint) but clients typically view these as a tick box exercise rather than a minimum requirement.
There are a few incentives such as a BREEAM rating, an independent assessment that results in a "grade" that can be used to market the sale or rent of the building, but again there is only a low number of commercial clients that want to explore this and only really if the costs associated are minimal.
These all link to the idea of using less as well but a lot of the time the bigger picture is often ignored. Hell, I could tell you of countless stories where Council projects are abandoned when new leaderships come in as they don't want to look to be finishing the previous administration's work. Think of the time, materials, labour, etc just thrown away because of the egos of those people pushing a "sustainable" agenda, it's sickening.
