As I have learnt from other source, using the slab preprocessor of Energplus is essential to get the correct ground coupling. I am modeling with Openstudio and would like to know if I can automate that functionality (e.g. by writing a measure) in order to use it within Openstudio and its Parametric Analysis Tool. Maybe someone has already written such a measure and could share with me. I am new to Openstudio and Energy+ and understood the logic of the slab program. But I am not an experienced energy+ programmer. So I am not sure how to implement it. Thanks a lot. Regards, Susanne
