Knowing how your building's energy efficeincy compares to others has traditionally been difficult to learn. Having the ability to compare the energy efficiency in neighboring buildings can lead to understanding the impact of best practitces and lead to improvements across all buildings.

The team's unexpected finding suggests that in the U.S. West and elsewhere, certain efforts to reduce harmful wintertime air pollution could backfire.
