MEP-Specific Calculation Approach - based on OneClick methodology #230

Closed ajensen19 closed 1 year ago

ajensen19 commented 3 years ago

Revised Calculation Method to Handle MEP:

Introduce two new parameters (EPD Dimension and Scaling Dimension) to accomodate EPD calculation without having to adjust the data in the underlying reference dataset for all item-based QuantityTypes. EPD Dimension will be set to zero by default, and then hardcoded as an additional property for Item-based MEP Quantity Types only. This allows the original datasets to stay intact, while providing the reference value needed for conversion. Scaling Dimension will be a user-set property that will be required to evaluate all Item-based MEP objects. This will also require a revision to the Evaluate method that multiplies by a ration of Scaling Dimension to EPD Dimension to properly adjust the resulting GWP according to user input. This ratio will be set to 1:1 for non-MEP objects. image

Two new properties in BHoM set to "1" by default. EPD Dimension; Specified Dimension. Specified Dimension is flagged for user input when doing MEP calc with QuantityType ITEM to force the user to adjust the calc.

Refers to out of date methods. Will be addressed in coming milestones generally.
