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.

Providing a proven set of energy efficiency measures and opportunities for saving energy and reducing operating costs for existing homes, this volume presents general tools and procedures for performing home weatherization such as insulation improvements as well as methods to reduce air leakage. The author describes several techniques and technologies that can reduce energy use or operating costs, including methods to retrofit existing homes to be net-zero energy buildings. Each chapter contains simplified calculation methods used to evaluate the effectiveness of various efficiency measures. The final chapter offers a series of case studies including examples of weatherized homes.
Developed over the course of many years of on-the-job projects involving HVAC energy auditing, testing/balancing and cost estimating, and refined through feedback from thousands of engineers and technicians who have used them, the forms contained in this manual are concise, comprehensive, and optimally organized for easy reference. Complete sets of forms are provided for all aspects of testing and balancing, energy auditing, indoor quality diagnosis, and load calculations. The first edition, entitled HVAC Energy Audit & Balancing Forms Manual compiled these time-saving forms for the first time in a single reference. This enhanced second edition adds a new chapter on technical management, providing procedures for achieving thorough, systematic and accurate problem solving, troubleshooting and decision making in building systems management and contracting.
Updated to include recent advances, this third edition presents strategies and analysis methods for conserving energy and reducing operating costs in residential and commercial buildings. The book explores the latest approaches to measuring and improving energy consumption levels, with calculation examples and Case Studies.
