Text found on the University website. 'A transition from the current state of energy production and consumption necessitates changing our ways of thinking toward a new set of collectively shared values, principles and frameworks beyond technological solutions. In order to imagine an architecture of transition, it is necessary to consider how energy has come to be incorporated and internalized in architectural thought and design. This project will collect, analyze and interpret historical and current visualizations of energy in science and architecture, resulting in an exhibition which will make energy visible to a broader public.'
