Green Building Energy Simulation and Modeling begins by providing essential insights into concepts and applications of building energy physics. The authors provide a brief, but rigorous, explanation of various modeling methods for building energy systems, order reduction techniques, and building energy simulation platforms (BESPs) that is followed by BES model validation techniques, testing, and evaluation. The book provides designers with the tools and methods they need to validate building energy systems and seize every opportunity to achieve greater energy savings and higher rating scores. Provides green building computer code Presents tactics on how to use energy studies and simulation to make informed design decisions early on-when you have the biggest opportunities to reduce costs Helps readers understand how and when to apply the different types of energy simulation at the appropriate design stage Evaluates passive and active strategies for limiting energy consumption and producing energy onsite.
