A Facility Manager's Introduction to Weather Correction for Utility Bill TrackingUtility bill tracking is at the heart of an effective energy management program. Merely comparing utility bills can yield inaccurate indications of the amount of savings from energy management programs due to the unaccounted influence of weather or other factors... Determining Energy Savings Using Utility Bills: A Winning Method for ESCOSAfter installing energy conservation measures (ECMs), Energy Service Companies (ESCOs) often determine the energy savings resulting from the project and present the savings results to their customers. A common way to calculate energy savings is to measure the flows of energy associated with the ECM, and then to apply spreadsheet calculations to determine savings... The Guide to Choosing the Best Desktop Utility Bill Tracking Software for Your FacilityToday's utility bill tracking software can deliver excellent results for energy managers who want to gain a comprehensive understanding of utility usage and costs in their facilities. All of the major commercially available utility bill tracking software programs are good at what they do, however, they are distinctly different in functionality and capacity. Three Powerful Utility Bill Analysis Methods for the Energy ManagerUtility Bill Tracking systems are at the center of an effective energy management program. However, some organizations spend time and money putting together a utility bill tracking system and never reap any value. This paper presents three utility bill analysis techniques which energy managers can use to arrive at sound energy management decisions and achieve cost savings. An Enlightened Approach to Budgeting and Goal Setting for the Energy ManagerEvery year energy managers need to report how much energy they saved and whether or not they met their energy savings targets. Most energy managers present reports comparing their current year's usage to energy usage from a previous year. Savings targets are typically a percentage of that previous year's usage. Setting targets and comparing in this manner usually does not generate an accurate estimate of energy actually saved...
