I studied architecture and practised in the field for over a decade, and I believe this experience has been essential because of my exposure to the exploding number of innovative building materials. During my early years of practice, I had a chance to research materials for a prominent project and was impressed by the challenges as well as opportunities associated with this task. I immediately saw a need to share this — which typically gets archived when a project is completed — with a larger audience of architects, designers, contractors, etc. I began an electronic journal and database, which quickly became popular with a growing audience of material enthusiasts who have given generous feedback. Over time, I have been able to appreciate the critical trajectories of material development as a result.

Although Europe and Japan are largely ahead of the curve, the United States has struggled with the development of sustainable building practices since the softening of the 1970s oil crisis that initiated much of the initial interest in green architecture in this country. I think the primary challenge to sustainable design is the fact that it has been viewed primarily as a long-term intellectual proposition without immediate economic benefit, and the relatively cheap cost of petroleum has made it nearly impossible to convince industries to consider other alternatives.

we have to face the discouraging truth about accelerating environmental degradation and act quickly to prevent it. Since buildings comprise roughly half of the problem in terms of energy use and emissions, vastly improved materials, construction methods and energy use should help significantly.

The title is a conflation of the words transformational materiality, and the book is the second volume of materials that have significant potential in shaping the physical environment through design innovation.

Ultraperforming materials attempt to push conventional performance boundaries; multidimensional materials enhance structural depth in order to maximise resources; repurposed materials are surrogates for more precious, conventional resources; recombinant materials are hybrids in which the sum exhibits superior characteristics to individual components; intelligent materials employ creative structural and formal ideas for enhanced environments; transformational materials undergo change based on environmental stimuli; and interfacial materials explore digital processes and fabrication.

The term often used is disruptive technologies — a title that suggests radical departures as opposed to incremental developments. One focus is materials whose behaviour conflicts with our traditional understanding — such as bendable concrete, transparent ceramics, or exfoliated graphite nanoplatelets. Another focus considers materials imbued with biomimetic qualities, like self-healing polymers, strong enviroboard, and active protection system. Another focus considers environmentally remediating materials such as Italcementi, Superabsorber, and Reben. Yet another focus relates to digital fabrication innovations, such as the Ombrae system, intaglio composites, and Erwin Hauer Continua.
