ONE introduction Introduction Aluminium Sympathetic and Powerful is the fifth book of the The Towards Sustainable Cities (TSC) research programme Towards Sustainable Cities (TSC) research programme, following is structured around the primary benefits of aluminium as on from Aluminium and Durability, Aluminium: Recyclability and articulated by The Future Builds with Aluminium website, http:// Recycling, and Aluminium Life Cycle Thinking, and Aluminium: greenbuilding.world-aluminium.org and The Aluminium Story Flexible and Light. The objective of the Towards Sustainable Cities website, thealuminiumstory.com. The first four books: Aluminium (TSC) research, funded by the International Aluminium Institute and Durability, Aluminium Recyclability and Recycling, Aluminium (IAI), is to quantify the in-use benefits of aluminium in architecture and Life Cycle Thinking, and Aluminium Flexible and Light, can be and the built environment. The programme was initiated by Chris downloaded as PDFs via world-aluminium.org/publications.

The city is about values, about aspirations, they are enlightening as well as offering prosperity.’ 2 Dr James Fox discussing cities and in particular cities in Japan considers that: Fig 1.1 Students of studioMARS, from The University of Nottingham, School of Architecture experiencing the Peace Fig 1.2 Dr James Fox in central Tokyo, courtesy of BBC 4 Bridge (2011) in Derry/London Derry, Northern Ireland, designed by architect WilkinsonEyre, on a wet and stormy night, November 2014. 8 aluminium: sympathetic and powerful introduction 9 Fig 1.3 The Thames River in central London – aluminium has become the background material of our contemporary cities.

Cities are engines of cultural change, because they throw people together to compete and collaborate and innovate. It the case around the world, but I can’t think of many countries more defined by their cities than Japan.’3 Cities are now the home for over half of humanity, however this should not be a concern. It should mean that humankind hones its skills in designing and developing cities within climate change targets of carbon usage, whilst protecting the overall biodiversity of planet Earth.
