Level 1 Screening Analysis
The first step in a Level 1 Screening Analysis is collecting data on your facility and its energy use. A walkthrough checklist can assist you. If all of the data requested in the walkthrough checklist is not readily available, a minimum of 12 months of electric and fuel bills as well as 12 months of steam use (where applicable) should be collected. (Note that bills for both delivery service for gas and electric and the commodity should be obtained — two sets of bills for each utility service.)
The NE RAC can help you to analyze the results of your data collection. A Level 1 Screening Analysis is a relatively quick analysis that is based on annual average costs, that uses estimated load profiles, and that uses other “rules of thumb” to estimate the project’s viability. The output normally includes savings, installed costs, and simple paybacks. The accuracy is usually within 30-50%.
