Using our own climate file (epw) allow us to know the data we are using in the model (energy consumption directly depends on the weather, it is as important as constructions materials) .
The revit box to edit the weather only allows us to enter some variables manually , wich takes unnecesary time. In adittion, the average daily oscillation represents a number that we have to calculate separately because does not appear in the climatic files (again, unnecessary calculations to trying to complete the table).

this table is very difficult to complete
