Pascal Lesage is a research officer at CIRAIG. His duties include research, tool development, supervision of graduate students, teaching, carrying out LCA studies and participation in LCA critical review panels.
The Tools Pole of Excellence aims to create life cycle assessment (LCA) software tools specifically tailored to the needs of clients, to operationalize LCA research in computational tools and to develop a suite of open-source modules that can be assembled to create cutting-edge LCA software tools when combined.
numpy.ndarrayfiles, and can be integrated in Brightway2 models using other modules (brightway2-aggregated, presamples). The resulting result arrays allow the use of aggregated LCI or LCIA results (also known as cradle-to-gate results) in LCA while also correctly integrating the uncertainty of LCI data, see Lesage et al. 2018. Generating samples of cradle-to-gate results for all activities in a database can be a lengthy process, especially when dealing with large LCI databases like ecoinvent. The functions are therefore geared towards large, bulk calculations, by e.g. facilitating multiprocessing and breaking down the task in multiple “batches” that can run on different systems.
