In August, Metals in Construction magazine will open registration for its 2024 Design Challenge. The tenth annual iteration of this popular ideas competition continues the tradition of calling for design strategies to help shape the welfare of society. This year, participants are invited to create and analyze a conceptual curtain wall scheme that integrates a range of technologies for harvesting energy. The purpose of this call for entries is to explore advancing use of the facade in lowering consumption by producing energy of its own. Participants may choose to incorporate harvesting technologies in either retrofitting or replacing the curtain wall of the site selected. Entrants will be asked to identify the types of energy being harvested, the elements used in its collection, and the methods for its measurement and storage. A $15,000 grand prize will be awarded to the design deemed most innovative and aesthetically appealing for producing energy, with the potential for being adopted for wide-scale use in an urban environment.
