A comparison of NOx emissions reductions is provided in Figure 2-1, which breaks down
the data by prototypical building type and by season. Again, office buildings are noted to
offer the most substantial opportunities for NOx reductions through CHP
implementation. By 2020, economic and population growth in HGB is anticipated to
create additional CHP opportunities in the commercial sector, which could result in even
greater NOx reductions.
