The important premise of this book is that the architects, as coordinators of the building design, must know the principles of the HVAC design and how the HVAC systems can be integrated into the building architectural design at minimum cost and without affecting the aesthetics. Architectural engineers will also find this book useful as the study of the HVAC is part of their curriculum and the book contains the necessary knowledge about HVAC, written in an easy-to-understand manner. This book could also be used by the young Architects preparing for the AIA examination. Specific details about integration of HVAC systems into the architecture of the building are included, such as: - How to position the air outlets for uniform distribution of air; - How to save energy through architectural features of the building; - How to select HVAC systems alternatives from technical point of view; - How to arrive at the best alternative through economic evaluations with emphasis on an abbreviated Life Cycle Cost analysis technique.
