Correctly Interpreting "Visualize Peak Loads for HVAC Sizing" Example?

Hi Chris / HB Community,

I’m new to the GH/HB community, but look forward to learning/better understanding tools. I am attempting to build something similar to what you’ve done in the following example (link below). I’d like for my GH definition to find the date, value of peak heat gain rate through building envelope (i.e. peak load calc rather than energy model), and breakdown of the peak load (conduction, radiation).

Link to Chris’s Hydrashare Example:,-512.3135574946664

Does this example run through all possible peak sensible load dates and not just the hottest week in the weather file? (i.e. looks at situation where solar load may create peak cooling load outside of weather file’s max drybulb dates). Based on the boolean toggles on the SimControl component I’m not sure which dates EnergyPlus is running through.

What are the default output units of the energyBalance component (kwh?)?

I’m trying to interpret your unit conversion process and what each row in the output excel file represents. Specifically, what are the units and time of year for each row? Based on an hourly simulation for the entire year I expected to see more rows i.e. one for each hour of the year. Then, assuming each column in a row represents the heat transfer (kwh) for one hour, I could sum across the columns of each row to find overall load for that hour, then look for the max value across all hours to find the peak load (which should be equal to the peak load output from the ReadEio component).

Could you shed some light on the energyBalance output units and output excel file?

Is there an available description / video walk through of this example?

Best wishes,
