Modern Construction Case Studies focuses on the interface between the design of facades, structures and environments of 12 building projects, all developed by Newtecnic. The Author compares facade technologies, particularly in the way they interface with structure and MEP (mechanical, electrical, plumbing services) in complex projects, to provide insights into the design process for building envelopes. Each envelope technology is described with an emphasis on one of three aspects: geometry, construction and performance. The analysis links the 12 case studies by comparing their structural and environmental performance. The aim is achieved by analyzing typical bays which are representative of each project and which illustrate the implications of using different building envelope technologies.
