Energy Management Process
The first step is to determine which audit is appropriate for a facility, given the complexity of its systems and buildings. Then, information may be collected on the structural and mechanical components that affect building energy use and the operational characteristics of the facility. Much of this information can be collected prior to the site visit. Evaluating energy use and systems before going on-site helps identify potential savings and makes best use of time spent on-site.
The audit consists of three distinct steps: preliminary data collection and evaluation, site visit, and analysis and reporting. An estimate of the time for each step can be made. Allocating time for each step leads to a more comprehensive and useful audit report. The following sections describe the tasks associated with each step of the audit process.
A pre-site review of building systems and their operation should generate a list of specific questions and issues to be discussed during the actual visit to the facility. This preparation will help ensure the most effective use of your on-site time and minimize disruptions to building personnel. A thorough pre-site review will also reduce the time required to complete the on-site portion of the audit.
The first task is to collect and review two to five years of utility energy data for all fuels, including electricity, natural gas, fuel oil, and any other delivered fuels. This information is used to analyze operational characteristics, calculate energy benchmarks for comparison to industry averages, estimate savings potential, set an energy reduction target, and establish a baseline to monitor the effectiveness of implemented measures. Several steps must be taken to ensure you have all the information required to do a thorough and accurate evaluation of energy consumption data.
