Parse a zone sizing (ZSZ) csv result file from an energy simulation to get data collections for the cooling/heating load over the peak design day.

## Inputs

* **zsz \[Required]**

  Full path to a zone sizing (ZSZ) csv result file that was generated by EnergyPlus. 

## Outputs

* **cooling\_load**

  a list of HourlyContinuousCollections for zone cooling load. There will be one data collection per conditioned zone in the model. 
* **heating\_load**

  a list of HourlyContinuousCollections for zone heating load. There will be one data collection per conditioned zone in the model.
