The principal objective of this work package is to test the overall consistency and feasibility of the approach before the software development takes place.

There will be a number of elements to this work:

• Review of definitions and data flow to check the consistency of the items and their interfaces.

• Cross check of model assumptions and data situation using the later case study cities as references

• Review of model assumptions with regards to realism and acceptability for the case study cities

• The work will involve a series of workshops between the model developers and the partners involved in this work package to allow for an on-going programme of revisions and improvements to the modelling approach.
