I have developed an EnergyPlus model for a house. I can measure the temperature variations and annual energy savings for different climates. I need to measure annual natural gas consumption/savings (m3.y-1). I would be thankful if anyone help me in this regard.

Are you looking for more than what's in the standard Annual Building Utility Performance Summary (or ABUPS), as reported in the eplustbl.htm file (i.e. "End Uses")?

Hi Denis, I appreciate your response. Yes, ABUPS. I have measured the annual energy consumption for heating and cooling purposes. Still, I need to calculate the annual average natural gas consumption for different cities, like the recently published article: Adv. Mater. 2023, 35, 2209897

OK. ABUPS provides (or supplies inputs to calculate) the following metrics:

  • total source/site natural gas use (in GJ/y), which you can convert to m3/y (~27 m3/GJ)
  • total source/site electricity use (in GJ/y), which you can also convert to m3/y ... if

... natural gas is part (%?) of the local energy mix (supplying grid electricity). EnergyPlus defaults to a ~3:1 source-to-site mix, which is sound for both nuclear and fossil-fuel grid generation. Something to consider if you're after total GHG emissions, for instance. Is that closer to what you're after?
