SCALE is a crucial aspect of architecture, especially when considering a building and evaluating its potential impact on the environment. Greenwashing spans from the scale of the single consumerist good to industrial products, to services, affecting also architec­tural artefacts, their technological components (glaz­ing, window frames, structural elements, etc.) the combination of building elements (walls, roofs, foun­dations, etc.), and the interaction of entire building complexes, neighbourhoods, and cities. The book is divided into three chapters. The first chapter gives a critical overview of the term Sus­tainability and its use in the design field, the second one contains the core concepts behind the publication and reflect the three sustainable design scales mentioned in the book title: CLIMATE, SITE/SETTLEMENT, and BUILDING. The last chap­ter offers a selection of sustainable design case studies around the world representative of four building-specific climate clas­sification types taking into account sun exposure, wind analysis, building materials and Mechanical Systems, functions, morphology and typology, and overall quality of space.
