Chimneys are among the most quietly persistent elements in architectural history. Yet their presence persists in nearly every cultural and climatic context, serving as a technical feature and a spatial, atmospheric, and symbolic device. It populates dense city skylines and anchors rural horizons alike, its vertical silhouette as ordinary as a window or a doorframe. This apparent ordinariness is deceptive. The chimney is one of the few architectural components that links the intimate scale of interior life with the expansive forces of the environment. For architects and designers, the necessity of the chimney presents a choice: to let it recede quietly into the building's functional fabric or to amplify it as a central, expressive element that shapes a project's identity.
Dübendorf, Switzerland is something of hallowed ground for architectural technologists. There, on the shared academic campus of the Swiss Federal Laboratories for Materials Science and Technology and the Swiss Federal Institute of Aquatic Science and Technology, public university ETH Zurich has conducted nearly a decade of engineering and construction experimentation at the ever-evolving NEST research building. In August, ETH Zürich unveiled its latest extension of the building, HiLo (short for high performance-low emissions)—a two-story modular addition to the chameleon structure that harnesses medieval building principles and contemporary digital methods to raise the bar for more sustainable applications of concrete.
The latest addition to Empa and Eawag's NEST research building in Duebendorf, Switzerland has officially opened. The innovative HiLo unit illustrates nearly a decade of formative ETH Zurich research in architecture and sustainable technologies, and features an intricate, doubly curved concrete roof, lightweight funicular floors, and self-learning building technology.
By now, it is clear that technology has taken over almost every aspect of our lives. It has changed the way we communicate, how we connect, how we work and study, and has even modified our buying and eating habits. Architecture and construction were not the exceptions, and technology is also now present in the way it is being thought, designed, and built.
