Hello everyone, I'm participating in a research project on "Interdisciplinary Analysis of Sign & Guidance Systems in Hospitals", in Lisbon, Portugal. The research will try to establish a model that will enable the understanding of the main difficulties about the use of these facilities. Since I'm starting to use the space syntax tools, and don't have much experience with them, i don't know which could be the best tool for this particular purpose. I see axman used in a lot of studies of large buildings, but also some use of Pesh, and lately of VGA. I have the first ones, and VGA i'll be trying to use it shortly. We were curious also about spatialist but Prof. Peponis seems hard to catch trough is email and i never succeeded in licensing it! We will focus our study in three Portuguese Hospitals, of three different time periods, each one representative of his "kind". The more recent one will be a contemporary building. They are all very large and at least one, with the services spread trough several contiguous buildings. Anyone has some experience in something similar and could give me some word of advice? Anyone with some experience in the tools could give me some hints in which would be a better option? Would it be interesting to use more than one of them? Wouldn't Axman and Pesh give similar results in this kind of use? Thank you for your time and attention, Victor Ferreira Faculty of Architecture, Lisbon, Portugal
