Commodity + Firmness + Delight

In his influential work De Architectura, Roman architect Vitruvius talks about the three elements of Architecture: Commodity, Firmness, and Delight. There are interesting parallels to the nature of façade engineering in that the building envelope needs to fulfil the functional requirements and meet the specified performance criteria, while having a fundamental impact on architectural aesthetics and the intangible qualities of the resulting enclosed space. This, then, is perhaps one of the aspects that appeal to a new generation of technically minded architects and architecturally minded engineers? There is no doubt that the nature of façade engineering can be both complex and stimulating. Appropriate application of highly specialised skills is potentially the difference between a successful project and a less successful one.

The need for specialist input stems from the gradual transition from traditional to non-traditional methods and technologies. Technological progress and the industrialisation of the construction industry mean that the role of the Architect is changing from that of controlling the design through a profound knowledge of materials and techniques to a role of orchestration of a multitude of specialist skills, knowledge, and industry intelligence – possibly benefiting from façade engineering input throughout the various stages of the design process. The increasing complexity of the technology and the recognition that not many architectural practices can sustain in-house skills in every field resulted in façade engineering as a relatively new professional discipline. The first façade engineering groups were set up around 20 years ago in response to the need for specialist input on technically challenging projects. Façade engineering covers the grey area between the more traditional disciplines but also overlaps significantly with all of them, to varying degrees depending on the circumstances.
