2016/1/20 · For example, when calculating the annual emissions of a boiler, you need to look at the total amount of fuel consumed by that boiler in a one-year period. On the other hand, if you have an emergency engine like a fire pump or backup generator, it isn't uncommon to see those activity metrics in terms of duration per time period; for example, fifty hours per year, ten hours per month, etc.
