Consider valuation of ancillary measure benefits

[trynthink]

We should think about how we can quantitatively capture ancillary benefits or "value streams" from various measures. These value streams are derived from a given measure but are not a result of the particular technology's energy efficiency. For example, envelope components can be a structural component of a building, supplanting other structural elements. As the efficiency of building components increases, the apparent energy benefit of an improved envelope declines, but that might be mitigated by including these additional benefits.

Good point. One such "non-efficiency" value stream that we've already discussed a bit is manufacturing competitiveness advantages associated with a certain measure. As we have touched upon, this ancillary benefit (and others we define) could be used to prioritize amongst measures with similar energy benefits. In any case, it would be useful to define a list of ancillary benefits that we see potentially warranting consideration in the program down the line.

Over time, we have added some of these benefits. We will continue to extend measure valuation when new needs are identified.
