Fundamentals of Building Energy Dynamics assesses how and why buildings use energy, and how energy use and peak demand can be reduced. It provides a basis for integrating energy efficiency and solar approaches in ways that will allow building owners and designers to balance the need to minimize initial costs, operating costs, and life-cycle costs with need to maintain reliable building operations and enhance environmental quality both inside and outside the building. Chapters trace the development of building energy systems and analyze the demand side of solar applications as a means for determining what portion of a building's energy requirements can potentially be met by solar energy. Following the introduction, the book provides an overview of energy usepatterns in the aggregate U.S. building population. Chapter 3 surveys work onthe energy flows in an individual building and shows how these flows interactto influence overall energy use. Chapter 4 presents the analytical methods,techniques, and tools developed to calculate and analyze energy use inbuildings, while chapter 5 provides an extensive survey of the energyconservation and management strategies developed in the post-energy crisisperiod. The approach taken is a commonsensical one, starting with the propositionthat the purpose of buildings is to house human activities, and thatconservation measures that negatively affect such activities are based on falseeconomies. The goal is to determine rational strategies for the design of newbuildings, and the retrofit of existing buildings to bring them up to modernstandards of energy use. The energy flows examined are both large scale(heating systems) and small scale (choices among appliances).Solar Heat Technologies: Fundamentals and Applications, Volume 4
