I try to calculate simple “conductivity” heat loss with constant outdoor temperature so i make this attachment in grasshopper. Is there a simpler way to do that ? Also grasshopper operateurs are not very practical.
It seems like the calculation is working? What part are you trying to revise or improve? It doesn’t really seem like you are using anything related to Honeybee (other than the constructions) - so which Honeybee element are you wondering about?
If you are asking if there is a Honeybee method for doing static calculations of this sort built in, I do not believe there is. Honeybee exports its models to OpenStudio and Energy+, which execute dynamic simulations, not static calculations of this sort.
If you are asking about the Grasshopper organization, a couple things might help when it comes to simplifying and organizing Grasshopper files:
Use ‘Clusters’ for repeating component sets
Create Python or C# scripts to execute repeating calculations or operations
Remove unnecessary components
Use ‘Groups’ to organize and sort the components into logically ‘sets’
Use DataTrees to execute multiple calculation streams within a single line of components
