During 2001 and 2002, a completely new edition of CIBSE Guide B was published in the form of five separate 'stand alone' books. This combined edition contains the five separate sections in one handy volume. Each section retains its own introduction, following a common format, which sets down a framework for making strategic design decisions. It has been necessary to renumber section headings, tables, equations and figures for consistency within the volume. A single, coherent index has been provided.
