For several decades the concepts of ecology and sustainability have generated influential currents of opinion in society, affecting all areas of our lives. Nowadays, no sensible person goes against the theory of global warming or the ever more pressing need to reduce greenhouse gas emissions. In the field of architecture, significant changes and developments are evolving. However, experience tells us that we still have a way to go. The percentage of sustainable buildings is still very low compared to the increased volume of building projects all over the world. Much more participation is still required on the part of everyone involved - from architects and building contractors to manufacturers of materials and end customers. This book gives this leading role to thirty selected international architects, all professionals who reveal the new trends in sustainable architecture and how they have contributed through their ideas to the basics of sustainable architecture.
