Abstract The awareness of the need for sustainable solutions has been increasingly growing and so is the concern of this matter for architecture. While the goal is that sustainability becomes progressively more popular and available for all, ecological solutions are still to be discovered and improved, and nowadays green materials add extra costs to an architectural project. Given this, this dissertation focuses on sustainability for the luxury market, more specifically on eco resorts in tropical countries. This thesis shows that, although this kind of hotel has an audience with a high purchasing power, the locations in which they are constructed and the communities that they involve are mostly underdeveloped.
