The first version of this "Atlas" contains over 100 cases of office air flow patterns for different ventilation systems. The book is designed to give the design engineer a quick idea of how a particular system works under various loads. Maps have been prepared for velocity, temperature, turbulent kinetic energy, percentage dissatisfied due to draft risk, and pollutant concentrations (caused by a smoker, bookshelf, or by building materials). So far, furnished office rooms have been analyzed with a k/e-turbulence model finite-volume computer code, and ventilating systems include the displacement and mixing type. The Poster explains how the computations were performed and how the Atlasmay be used.
