About the design of the book. " Hot to Cold " presents an attractive design that is displayed , suddenly , in its combination of colors (gradient from red to blue), which are arranged on its cover and in its leaves (edges ). Their pages extension (700) is more than can be expected due to its price ($ 30, Amazon ) relatively modest for specialized books on architecture; another important mention his very suitable for reading dimensions deserves. Content structure refers to the name of the book, for that reason, BIG projects are ordered from those located in the hottest parts of the globe (Persian Gulf) to the coldest (northwest Europe). However, when reviewing this becomes a -as it says his subtítulo- odyssey, as countless renderings and diagrams become cloying on the passing of the pages. It takes intermediate between each tranche of projects such as descriptive texts, which would only enrich the design description. BIG continues with the Archicomic format, raised from its predecessor - and bestseller - " Yes is More " with the significant improvement in the readability of the texts. The great debt to this format (archicomic) is that in most projects renderings lose communication that should be due to saturation of these. Yes, Yes is More, but "Less is enough" when presenting renderings is. About the book 's content. "Hot to Cold" not looking to become a book of theory and criticism of architecture, but in a graphic catalog architectural operations and results around the world. The reflection of the opening pages is extremely necessary for the purposes of BIG, showing that the great problem of the international architecture is its indifference to context; That is evident when contrasted with graphics- -through vernacular architecture. Bjarke Ingels summarizes this in a simple question: If these buildings (International Style) are located in different places, why all are equal? In turn, the philosophy of the Danish study, the "hedonistic sustainability" is reinforced with reflection "Engineering without engineers" which describes that by design can capitalize on natural ventilation, sun exposure, and pedestrian mobility; creating increasingly less dependent on "machinery" buildings. The highlight of the projects presented to us BIG are their processes or morphological operations (torsion, orientation, extraction, extrusion, etc.) very well explained in his plots, which deserve special qualification to be as explicit and logical. Despite the remarkable design processes, the debt is in the final product, which are difficult to analyze because the book -in the planes are fuzzy and blurred. If you want a good book for reflection architectural possibly "Hot to Cold" is not the most adequate, however, if you are willing to visually train your graphic expression to represent a design process,guide to approach competition projects "Hot to Cold" is a -o reading rather, review- highly recommended.
