eTool have an internal procedure for certifying designs that evolves with our software and our experience.  Essentially we check the users inputs to ensure that the LCA model complies with the system boundary, scope, and accuracy requirements.  We have a mix of automatic reports and manual processes that we run through to check the users inputs.  We also compare the project to similar projects in the growing eToolLCD database which provides a good ‘sense check’ on not only the over-all result but also individual elements in the building.
