This book is the cumulative work of Professor Phu Hoang's studio, "School Without Classrooms." The studio investigated two extreme scales of the environment, the local and immediate scale of weather and the global, or long term, scale of climate. While it is true that the basic difference between weather and climate is time-based, they have increasingly become differentiated in the granularity of their scale and resolution. The emergence of micro-weather forecasting with mobile technologies has made it possible to know upcoming weather with more immediacy and at a higher resolution than previously possible. The studio explored the concept of “indoor urbanism” and its potential to radically change how we experience weather in our cities and within the interior environments of buildings, blurring the boundary between them.
