The annual component loads summary [closed]
I am trying to get the annual cooling load contributed by window solar, window conduction and external wall.
I know in eQUEST and DOE-2, there is a report about cooling load which provides the annual accumulated cooling loads of different components, named "win sol, win con, wall". But in EP, I cannot find a similar report or variables.
In EP, the "component load summary" report seems can provide these loads for zones (in "estimated peak cooling load component"), but only the PEAK load is presented here. This means the EP can make such kind of calculation. In the Engineering Reference, it is stated that this calculation is only be done for the sizing days.
Does this mean I cannot use EP to get the annual cooling load contributed by different components? Thanks for your help in advance!
@Fox-NUS If you are only interested in seeing annual summaries of typical sensible load contributions in each zone, then add the Sensible Heat Gain Summary option to the
Output:Table:SummaryReportsobject. If you want to see these at hourly or monthly frequencies, then useOutput:Variableobjects as defined in this post.Hi, Aaron, Thank you for the answer. However, what I wanna get is the heat gain caused by solar or temperature difference as what is put in "component load summary". The heat gain in Energyplus is based on the heat balance algorithms which combines the effect of solar, temp, internal load. Because I just want to study the effect of envelope and weather conditions, the heat gain in Sensible Heat Gain Summary or any Output:Variable is not the direct indicators.
As I mentioned, the DOE-2 and EQuest or other programs can provide such results. Energyplus is so powerful, I believe there is a way to get the same thing. In the report "component load summary" and the Engineering manual, it does mention Energyplus can do such calculation, which is based on radiant time series (RTS) method. But I cannot find the annual load but the peak cooling/heating load.
