ABSTRACT

This section will provide information on performing energy audits.

Introduction

Many of the busiest buildings today are quite old. Some of these buildings waste large amounts of energy, resulting in higher loads on the grid as well as increased operational costs. Furthermore, the energy demands of our society are on the rise. These factors, combined with the climate change dilemma, indicate that before increasing energy output, the load on the grid should be reduced. By auditing existing facilities, large gains in efficiency can be made. These gains result in a reduction in energy consumption as well as monetary savings. Often, solutions to problems require little to no money and involve only a change in operational philosophy. In the case of retrofitting, most payback periods are on the order of a few years or less. These retrofits can provide large efficiency gains while adding a negligible amount of maintenance. This page is intended to be used as a basis for performing energy audits. It provides a general guideline for auditing and the suggested data to collect. Every situation is unique, however, and care should be taken to ensure that the proper solutions are being implemented.

Design

To begin, the main components of the building will be inspected to yield the required information to perform an efficiency analysis. Most of this information could be gathered from the manufacturer and/or the equipment operator.
