Heating and cooling load Analytical Surfaces with Revit API

Is possible to extract heating and cooling load Analytical Surace with Revit Dynamo and export it to Excel? I wish to extract parameters like Wall Area and direction, Glazing Area.
The main goal is to extract the data of wall area and direction from Revit and import to other software to conduct heat load estimation(By HAP, excel sheet).

furthermore, the gbXML from Revit does not work, the walls seemed to broken up too much in the Revit model when i open using HAP or CVS since The Analytical Model that is produced from gbXML differs from the Physical Model that is in Revit Views. I believe the best way is to find an approach to extract data by API.

does it useful to use this code to access to Analytical Surface ?
