This practical handbook explains the process of planning and carrying out energy audits of electrical, mechanical, and building systems in any type of facility. Following an overview of energy auditing basics to gauge efficiency, Thumann (executive director, Association of Energy Engineers) et al. go into greater depth for each step of the energy-consumption data gathering and evaluation process. Detailed example calculations, sample energy audit forms, conversion factors, and a glossary are provided. The ninth edition adds chapters on retro-commissioning and investment grade energy audits.
