The New Calculation Engine In SimaPro 8
SimaPro 8 has been equipped with a completely new calculation engine. The reason for this is simple. The old calculation engine worked well with life cycle assessment (LCA) models of a few thousand processes. But with the introduction of ecoinvent 3 - resulting in much larger models - SimaPro needed a software update to continue supporting the available data sources.
SimaPro 8 | What is new in SimaPro 8?
PRé is proud to present the new release of SimaPro 8 equipped with an updated database that includes ecoinvent v3. The most important improvements are the introduction of ecoinvent 3 and of regionalized water footprint methods, the update of existing impact assessment methods, and a significantly quicker calculation engine. Please read the report for more details.
