During my research for a building analysis solution suitable for early design phases I came across these two quite comprehensive abstracts about Ecotect. I like Ecotect for that it can give you that kind of graphic output that is so important to communicate this rather intangible information to a client. As well I believe if information is visualised the way Ecotect does it triggers the visual thinking of designers and will lead to more effective problem solving.
