Twenty-five years ago glass facades to buildings were regarded as architecturally passe and ecologically irresponsible. Now they are seen as the natural skin for urban buildings and, when properly designed, as the best for environmental control as they can harness the energy gain from solar radiation.
Twenty-five years ago glass facades to buildings were regarded as architecturally passe and ecologically irresponsible. Now they are seen as the natural skin for urban buildings and, when properly designed, as the best for environmental control as they can harness the energy gain from solar radiation. So that glass facades may be worthy of their new status, they must be well designed, hence the importance of a book like this which sets out the issues simply. The first edition of this book was published four years ago, but the technology is developing fast, and this new edition has new buildings and new projects. The book is in six sections; the first deals with glass as a material, followed by the glass pane, laminated glass, insulating glass, facades and finally intelligent glass facades. Most architects will head for the last chapter. It soon becomes clear that designing a building to reduce energy consumption is a complicated business, involving the whole building, not just the facades. It also becomes clear that many of the most effective ways of reducing energy consumption are expensive to install and operate and the owners will never recoup this cost through lower fuel bills. So the motivation behind some of the elaborate facades in this book must be idealistic, not financial. The science still has some way to go, but we should all be grateful that so many building owners are willing to pay so that the technology can advance towards the economical, environmentally-friendly buildings that we all need
