Buildings account for almost half of total primary energy use and related greenhouse emissions worldwide. Although current energy systems are improving, they still fall disappointingly short of meeting acceptable limits for efficiency.

Well-trained energy auditors are essential to the success of building energy efficiency programs—and Energy Audit of Building Systems: An Engineering Approach, Second Edition updates a bestselling guide to helping them improve their craft. This book outlines a systematic, proven strategy to employ analysis methods to assess the effectiveness of a wide range of technologies and techniques that can save energy and reduce operating costs in residential and commercial buildings.

Useful to auditors, managers, and students of energy systems, material is organized into 17 self-contained chapters, each detailing a specific building subsystem or energy efficiency technology. Rooted in established engineering principles, this volume:

  • Explores state-of-the-art techniques and technologies to reduce energy consumption in buildings
  • Lays out innovative energy efficiency technologies and strategies, as well as more established methods, to estimate energy savings from conservation measures
  • Provides several calculation examples to outline applications of methods

To help readers execute and optimize real building energy audits, the author presents several case studies of existing detailed energy audit reports. These include results from field testing, building energy simulation, and retrofit analysis of existing buildings, with recommendations based on sound economic analysis. Examining various subsystems, such as lighting, heating, and cooling systems, it provides an overview of basic engineering methods used to verify and measure actual energy savings attributed to energy efficiency projects. The author presents simplified calculation methods to evaluate their effectiveness and ultimately improve on them. Ideal either as a professional reference or a text for continuing education courses, this book fortifies readers’ understanding of building energy systems, paving the way for future breakthroughs.

The JUT AMlIACM Symposium on Discretization Methods in Structural Mechanics was nd th held in Vienna, Austria, from 2 to 6 June 1997. The site of the Symposium was the "Theatersaal" of the Austrian Academy of Sciences. The Symposium was attended by 71 persons from 23 countries. In addition, several Austrian graduate students and research associates participated in the meeting. In the 5-day Symposium a total of 48 papers were presented. All of them were invited and accorded equal weight in the programme. The following topics were covered: • Error-controlled adaptivity of finite element methods • Large deformations and buckling, including inelastic deformations • Inelastic brittle or ductile localization, phase transition and system failure, resulting from monotonic, cyclic or impact loading • Sensitivity analysis and inverse problems with special emphasis on identification of material parameters • Development of linear and nonlinear finite element methods for thin-walled structures and composites • Implicit integration schemes for nonlinear dynamics • Coupling of rigid and deformable structures; fluid-structures and acoustic-structure interaction • Competitive numerical methods (finite element methods, boundary element methods, coupling ofthese two methods) • Identification of material and structural data. Comments on details of the treatment of these topics are contained in the Concluding Remarks. The Editors would like to express their appreciation to E. Stein who has prepared these Concluding Remarks.
Optimal analysis is defined as an analysis that creates and uses sparse, well-structured and well-conditioned matrices. The focus is on efficient methods for eigensolution of matrices involved in static, dynamic and stability analyses of symmetric and regular structures, or those general structures containing such components. Powerful tools are also developed for configuration processing, which is an important issue in the analysis and design of space structures and finite element models.
Different mathematical concepts are combined to make the optimal analysis of structures feasible. Canonical forms from matrix algebra, product graphs from graph theory and symmetry groups from group theory are some of the concepts involved in the variety of efficient methods and algorithms presented.
The algorithms elucidated in this book enable analysts to handle large-scale structural systems by lowering their computational cost, thus fulfilling the requirement for faster analysis and design of future complex systems. The value of the presented methods becomes all the more evident in cases where the analysis needs to be repeated hundreds or even thousands of times, as for the optimal design of structures by different metaheuristic algorithms.
The book is of interest to anyone engaged in computer-aided analysis and design and software developers in this field. Though the methods are demonstrated mainly through skeletal structures, continuum models have also been added to show the generality of the methods. The concepts presented are not only applicable to different types of structures but can also be used for the analysis of other systems such as hydraulic and electrical networks.
