The book “Building Energy Audits-Diagnosis and Retrofitting” is a collection of twelve papers that focus on the built environment in order to systematically collect and analyze relevant data for the energy use profile of buildings and extended for the sustainability assessment of the built environment. The contributions address historic buildings, baselines for non-residential buildings from energy performance audits, and from in-situ measurements, monitoring, and analysis of data, and verification of energy saving and model calibration for various building types. The works report on how to diagnose existing problems and identify priorities, assess, and quantify the opportunities and measures that improve the overall building performance and the environmental quality and well-being of occupants in non-residential buildings and houses. Several case studies and lessons learned from the field are presented to help the readers identify, quantify, and prioritize effective energy conservation and efficiency measures. Finally, a new urban sustainability audit and rating method of the built environment addresses the complexities of the various issues involved, providing practical tools that can be adapted to match local priorities in order to diagnose and evaluate the current state and future scenarios towards meeting specific sustainable development goals and local priorities.

This book is designed to provide you with the fundamental knowledge you need to evaluate how energy is used in commercial facilities, establish accurate baseline information, and identify where energy consumption can be reduced. The book will also provide you with all the information you need to establish an energy audit program for your facility. Energy accounting procedures, electrical, mechanical, building and process systems analysis, life cycle costing, and maintenance management are all covered in detail.

Existing literature on energy audits consists almost exclusively of practical guides. This book looks at energy auditing from a scientific perspective. It discusses the nature of energy audits and provides a universally applicable data model as a basis for automatic processing of a large number of energy audits. Qualitative aspects of auditing are discussed in detail. The modeling enables an improved evaluation of subsidy programs for energy audits, but also a systematic and teamwork-oriented creation of energy audits.

The Intuitive Guide to Energy Efficiency and Building Improvements Energy Audits and Improvements for Commercial Buildings provides a comprehensive guide to delivering deep and measurable energy savings and carbon emission reductions in buildings. Author Ian M. Shapiro has prepared, supervised, and reviewed over 1,000 energy audits in all types of commercial facilities, and led energy improvement projects for many more. In this book, he merges real-world experience with the latest standards and practices to help energy managers and energy auditors transform energy use in the buildings they serve, and indeed to transform their buildings. Set and reach energy reduction goals, carbon reduction goals, and sustainability goals Dramatically improve efficiency of heating, cooling, lighting, ventilation, water and other building systems Include the building envelope as a major factor in energy use and improvements Use the latest tools for more thorough analysis and reporting, while avoiding common mistakes Get up to date on current improvements and best practices, including management of energy improvements, from single buildings to large building portfolios, as well as government and utility programs Photographs and drawings throughout illustrate essential procedures and improvement opportunities. For any professional interested in efficient commercial buildings large and small, Energy Audits and Improvements for Commercial Buildings provides an accessible, complete, improvement-focused reference.

Procedures for Commercial Building Energy Audits provides purchasers and providers of energy audit services with a complete definition of good procedures for an energy survey and analysis. It also provides a format for defining buildings and their energy use that will allow data to be shared in meaningful ways. This publication specifically avoids a "cookbook" approach, recognizing that all buildings are different and each analyst needs to exercise a substantial amount of judgment. Instead, Procedures sets out generalized procedures to guide the analyst and the building owner, and provides a uniform method of reporting basic information. Different levels of analysis are organized into the following categories:Preliminary Energy Use Analysis Level I Analysis "Walk-Through Analysis Level II Analysis"Energy Survey and Analysis Level III Analysis"Detailed Analysis of Capital-Intensive Modifications The book comes with a CD that provides more than 25 guideline forms, with explanatory material, to illustrate the content and arrangement of a complete, effective energy analysis report. The CD provides these forms in both PDF and Word format, enabling you to customize and print each form. For the downloadable version, the PDF of the book and the guideline forms are included in a single .zip file. You will need WinZip or an equivalent program to open the file. ASHRAE Research Project 669 and ASHRAE Special Project 56.

Energy efficiency is today a crucial topic in the built environment - for both designers and managers of buildings. This increased interest is driven by a combination of new regulations and directives within the EU and worldwide to combat global warming. All buildings now must now acquire and display an EPC (energy performance certificate), a rating similar to the A–G rating given to white goods. But in order to understand how to be more efficient in energy use, you need first to understand the mechanisms of both energy requirements and how energy is used in buildings. Energy Audits: a workbook for energy management in buildings tackles the fundamental principles of thermodynamics through day-to-day engineering concepts and helps students understand why energy losses occur and how they can be reduced. It provides the tools to measure process efficiency and sustainability in power and heating applications, helping engineers to recognize why energy losses occur and how they can be reduced utilizing familiar thermodynamic principles. The author describes the sources of energy available today; explains how energy is used in buildings – and how energy is lost - and how this can be controlled and reduced. Investments in energy efficiency are considered for a number of case studies conducted on real buildings The book explains the theory; illustrates it with case studies and worked examples; and then tests students’ understanding with tutorial problems. This is an invaluable resource for students on engineering and building courses where energy management is now a core topic.
