2000 years ago the Roman architect Marcus Vitruvius Pollio wrote the ten books on architecture still referred to in every architect’s education. The concept of an architectural pattern book offering design principles as well as solutions is universally familiar and this is the green pattern book for today.Now fully updated to provide an introduction to sustainable architectural design suitable for both undergraduate and postgraduate courses, this well established textbook emphasises the importance of location specific architecture that responds to local climate conditions and uses local materials, as well as offering better architectural quality with more natural and fewer artificial inputs.Not only is less more, less is also beautiful.
