Sustainable Steel Buildings reviews steel and its potential as a sustainable building material and shows how steel can be used to deliver buildings and structures with a high level of sustainability. The book's main focus is on the advantages and disadvantages of steel and how those characteristics can be used under a range of international certification systems (DGNB, LEED, BREEAM, openhouse etc).
