It's an interesting question. As far as I know, there is no formal process for doing that. We frequently meet with companies that are interested in talking to us about their technologies. We are open to doing that. From where my office sits, we certainly work hard to make connections with them and others across the system to make sure they are able to communicate the benefits of their technologies. But as far as I know, there's no system across government for identifying specific technologies to pursue.
In the approach that we take within Public Works, which I think is a fairly widely used approach, it's results that are required as opposed to defining the technology. We will have requirements vis-à-vis the energy efficiency of a building. We may have requirements vis-à-vis a design, for example, that it must be LEED gold. It requires that a certain amount of energy must actually be generated by the building. But we wouldn't specify that the building must have a heat pump or that the building must have a certain amount of solar power.
