In Energy Efficient Buildings: Fundamentals of Building Science and Thermal Systems, distinguished engineer and architect Dr. John Zhai delivers a comprehensive exploration of the design and engineering fundamentals of energy efficient buildings. The book introduces the fundamental knowledge, calculations, analyses, and principles used by designers of energy efficient buildings and addresses all essential elements of the discipline.
An essential guide for students studying civil, architectural, mechanical, and electrical engineering with a focus on energy, building systems, and building science, the book provides practical in-class materials, examples, and actual design practices, as well as end-of-chapter questions (with solutions) and sample group projects.
Readers will find:
A thorough introduction to the cross-disciplinary approach to the design of energy efficient buildings
Comprehensive explorations of all critical elements of energy efficient building design, including standards and codes, psychometrics, microclimate, thermal comfort, indoor air quality, HVAC systems, and more
In-depth discussions of the foundational knowledge, calculations, analysis, and principles needed to design energy efficient buildings
Practical in-class examples and end-of-chapter questions with solutions for students, and design guidance and sample group projects for use in course lectures and actual design practices.
Perfect for graduate and advanced undergraduate students studying building environmental systems, building systems in construction, and mechanical and electrical systems in construction, Energy Efficient Buildings: Fundamentals of Building Science and Thermal Systems will also earn a place in the libraries of practicing civil, architectural, and mechanical engineers.
Zhiqiang (John) Zhai, PhD, is Professor for Building Systems Engineering in the Department of Civil, Environmental and Architectural Engineering at the University of Colorado at Boulder. He obtained his first doctorate in Engineering at the Tsinghua University and his second doctorate in Architecture at the Massachusetts Institute of Technology, and his research is focused on thermal and environmental systems, indoor and outdoor environmental quality, and sustainable and immune buildings.
