I would agree that the code is an important tool to move the builders along the green building continuum. That's important.
The codes are designed right now for the lowest common denominator—the laggards, if you will. Codes should be designed to help provide a pathway to a better place and incrementally grow and bring everybody along with them. You're always going to have the push and pull with industry in codes and regulations. I understand that challenge all the time.
But codes are only one part of it. You can't just raise a code and assume that the builder capacity is there to actually reach that threshold. Governments have a role to play in that regard to help build capacity or always facilitate the industry's capacity to effectively develop its way toward the pathway the government wants to see them move to—in this case, net-zero energy. It's not a single solution, but one part of it.
