This book explains the key concepts of energy simulations, build simulation models and use of these models to integrate daylight and energy efficiency in their building designs. It covers the key concepts of energy simulation, construction of the building with respect to geometry and materials used. It explains HVAC and photovoltaics as a medium to improve energy efficiency and energy generation, respectively. It covers heating and cooling design including simulating different types of HVACs and impact of photovoltaics for energy generation. It is aimed at students, researchers in building energy (simulation)/building design courses, energy simulation professionals, architects and so forth. Explains the building physics and related concepts behind energy performance of building without relying on high-level mathematics Covers the simulation of dynamic shading techniques and daylighting strategies, offering insights into optimizing building performance Discusses the analysis of individual components of centralized HVAC systems Includes the simulation of on-site photovoltaic systems by looking at their placement and its effect on energy generation Focusses on adaptive controls in naturally ventilated buildings It is aimed at students, researchers in building energy (simulation)/building design courses, energy simulation professionals, architects and so forth.
