The first GreenWIN Technical Sub Group Skype Meeting took place on the 13th of December 2018. This meeting was agreed during the first partners meeting earlier in November, and focused on the technical aspects of the project. It was agreed that all partners will supply more detailed data on the proposed trial sites to the University of Liege by mid-January 2019. This will allow for a meeting at the end of January in Birmingham where the design specifics for the ‘test bench’ laboratory trials will be formalised with testing to follow. Each testing procedure should be approximatively one week, with the first test session possibly taking a little bit longer.
