Architecture is increasingly understood to be a sensual, spatial experience, which means that the experience of buildings and spatial constellations is also a perception of atmospheres that are rated as positive or negative. Architects, planners, investors, and politicians must produce effects such as these according to intersubjective and communicable criteria, and not intuitively or randomly. Architectural Atmospheres addresses the growing awareness of the atmospheric dimension of architecture and provides a current, programmatic discussion of this topic. What possibilities does this approach open to architecture, what value does this knowledge have? Three essays and a conversation lead a cross-discipline discussion on the impact of architecture, and contribute to the debate first initiated by Peter Zumthor. The texts are accompanied by thirty-five color images that capture architectural moods in a variety of ways.
