Architects, what will it take for sustainable architecture to become the norm rather than the exception?

Full transparency.

I've been a project manager for a large custom home builder for about 10 years. I was a former Architecture Major as well. I recently resigned to focus more on technology, specifically construction. I've taught myself to program to prepare for this transition over the past few years. I'm very much still passionate about residential architecture and luxury design and I'd like to build something to help.

I've come to speak directly to established architects and ask, "What do you think the world needs to be more accepting of sustainable architecture as a standard and not a 2nd option?"

And by sustainable, I don't just mean materials and energy efficiency. I believe sustainable architecture is a combination of great, functional design, site orientation, well-designed urban planning, and buildings that are crafted to last for centuries because they were built and designed properly for their given environments.

I'm happy to speak with anyone on an individual level or here in the thread who has any positive thoughts on this.
