OS building end use demand meter

asked 5 years ago

updated 5 years ago

I need to gather hourly data of building (not by thermal zone or space) energy (kWh and terms) and demand (kW) by end-use (i.e. lighting, heating, cooling, fans, etc). I see that the .mdd file (as well as an Add Hourly Meters measure on the BCL) allows us to gather hourly data in J (which is find I can post-process) for energy use (kWH and therm) by demand for building end uses, but I don't see an option to add end-use demand meters. Does anyone know of another way/trick to produce meters or variables that report whole building demand by end-use, preferably within OpenStudio and not running the IDF in energyplus?

I know I can add output variables for end-use demand (kW) but the hourly data is output per thermal zone and I have some large models with many thermal zones and would prefer not to post-process to this extent or be required to run energyplus.

You could generate the output meter for end-use energy, then post-process the meter data to divide by the reporting frequency to get the end-use demand. For example, if your output meter was 1,000 kWh and it was reported every 15 minutes (0.25 hours) to match your simulation timestep, then the demand would be

1,000kWh0.25h=4,000kW
