Parse the peak load and HVAC component sizes from an SQL result file that has been generated from an energy simulation.

### Inputs

* **sql \[Required]**

The file path of the SQL result file that has been generated from an energy simulation.

* **comp\_type**

An optional name of a HVAC component type, which will filter the HVAC components that appear in the output comp\_props and comp\_values. Connecting nothing here will mean that all HVAC component sizes are imported and a full list of possible components will appear in the comp\_types output.

### Outputs

* **zone\_names**

A list of zone names (honeybee Room identifiers) that correspond to the zone\_peak\_load and zone\_peak\_heat below.

* **zone\_peak\_cool**

A list of numbers for the peak cooling load of each zone on the summer design day. These correspond to the zone\_names above. All values are in Watts.

* **zone\_peak\_heat**

A list of numbers for the peak heating load of each zone on the winter design day. These correspond to the zone\_names above. All values are in Watts.

* **comp\_types**

A list of HVAC component types that are available in the results. This will be equal to the input comp\_type\_ if a value is connected.

* **comp\_properties**

A list of text descriptions for HVAC component properties. These correspond to the comp\_values below.

* **comp\_values**

Values denoting the size of various zone HVAC components (eg. zone terminal sizes, boiler/chiller sizes, lengths of chilled beams, etc.). These correspond to the comp\_properties above. Values may be in different units (eg. W, m/s, etc.) depending on the property of the component being observed.
