I have met a few architects who never discuss "Green" or "Sustainability" with their clients. They simply design that way. Their clients may or may not be aware of the value they are getting. The objectives discussed are the metrics of clean air, wellness, comfort and low energy costs as integrated with the aesthetics. This should apply to all members of the project team extending to all other consultants.
