One Metric May Not Be Enough, but Some Are Better Than Others

When trying to judge a building's energy performance considering both economic and environmental factors, one metric may no longer be sufficient.  It may be more useful to consider multiple complementary metrics, while finding a metric that provides a good compromise solution for many purposes today.  This presentation will hypothesize why the TDV and emissions metrics may be the most useful over time for societally beneficial decisions.  In the meantime, the use of a metric such as normalized modified end use loads may provide a good enough compromise to satisfy competing stakeholders in the residential marketplace.
