I believe we need some time.
The problem is twofold. You have the issue of new construction and the issue of existing buildings. With respect to the new construction, what we need more than ever is to modify the building code. The building code is woefully inadequate for our climate and not focused on energy efficiency as much as it could be. The technology is ready.
With respect to existing buildings and infrastructure, farmers need help to do that work. It's a large undertaking to retrofit a barn to be much more airtight and insulated and to have heat recovery ventilation. There are probably going to be unique heat recovery ventilation issues that arise with the dust and contaminants that are in livestock facilities that aren't seen in a shopping mall, for instance.
I'm not suggesting there's a silver bullet ready here, but we know how to do it. The engineering principles are sound, but farmers need assistance to do it.
