Behind Architectural Filters: Phenomena of Interference explores the active role of architectural filters in generating physically and sensory charged spatial experiences. This book explores architectural filters as connecting mechanisms capable of conjuring unique atmospheres that integrate the participation of several agents. The text analyzes ten case studies, grouped under five generative parameters: origin, density, thickness, function, and message. Each study investigates the main aspects of the filters' internal genesis and the character of the spaces informed by them. The cases illustrate a broad geographic, cultural, and historical scope, and connect past tradition with contemporary design. This methodology considers a historical and philosophical standpoint addressing vernacular, constructive, sustainable, and sensory considerations. Written for students and scholars of architectural history, theory, art, design, and philosophy, Behind Architectural Filters: Phenomena of Interference offers an unprecedented perspective on the production of spatial atmospheres, bridging past and present while connecting thought and practice in a highly visual study.
