EnergyCAP is built around the concept of making energy information actionable. The software provides multiple options for viewing and interpreting utility bill data.
EnergyCAP’s predecessor software originally pioneered cost avoidance and measurement & verification calculations. Adhering to Option C, the “Whole Facility Method” in the International Performance Measurement & Verification Protocol (IPMVP), EnergyCAP’s cost avoidance continues to be a valuable function in EnergyCAP.
Cost avoidance works by comparing current bills with a normalized baseline year. The normalization process automatically takes into account major variables including weather (degree days), billing period length, floor area changes and commodity price, and allows the analyst to enter adjustments for other changes such as occupancy, schedule and equipment retrofits.This enables you to compare energy use and cost from year to year to get an accurate handle on savings.
Normalization helps compare year-to-year utility expenses on an “apples-to-apples” basis using weather data. After you select a base year, EnergyCAP puts energy use into daily “buckets” and then allocates each to the appropriate calendar month. After that, EnergyCAP adjusts weather-sensitive meters to reflect the degree days in the user-selected weather normalization year. The result is a kind of cost avoidance that can be very useful for quantifying energy management savings.
Calendarization more accurately allocates utility bill usage and cost data for reporting purposes by dividing the data into daily “buckets” and allocating them to the appropriate calendar month using weather adjustments. This tool is helpful in comparing month-to-month and year-to-year utility bill data and “smoothing out” quarterly or annual invoices across multiple months.
Use vs. Weather graphs in EnergyCAP reveal correlations between these two variables. By comparing monthly degree days with meter energy use, it is possible to derive a meter profile expressing the weather sensitivity of that meter. How does EnergyCAP know when a meter is weather sensitive? A statistical linear regression analysis correlates the energy use recorded on each bill with the corresponding degree days in the billing period.
On Use vs. Weather charts, the vertical axis is the average daily use and the horizontal axis is the average number of heating or cooling degree days per day. If the regression line rises from left to right, it means that months with more degree days have more use, suggesting that a portion of the energy use is weather sensitive.
Energy Use Intensity (EUI) is a useful metric to monitor long-term energy efficiency trends for a building. ENERGY STAR defines EUI as “a unit of measurement that describes a building’s energy use. EUI represents the energy consumed by a building relative to its size. A building’s EUI is calculated by taking the total energy consumed in one year (measured in kBtu) and dividing it by the total floor space of the building.”
EnergyCAP uses weather-normalized energy use to calculate annualized EUI and displays it on a trend chart. EnergyCAP can also roll up EUI values at every level of the organization hierarchy. This functionality provides a valuable picture of long-term energy efficiency trends for each department, division, region, and business unit, as well as for the entire organization.
Comparing similar buildings and meters enables you to spot outliers that suggest opportunities for savings. Using these powerful visual aids, you can rank and compare buildings and meters within peer groups based on the criteria you choose, such as building or meter primary usage, commodity, vendor, or rate. Once you’ve identified an outlier, it’s easy to prioritize energy conservation efforts. Benchmarking groups are created automatically by EnergyCAP based on common attributes, by users through a manual process, and by filters using User-Defined Fields.
EnergyCAP takes the guesswork out of energy budgeting by helping you create detailed meter-by-meter and month-by-month budgets based on up to three years of historical utility bill data. Granular budget information can be “rolled up” and summarized at any level of the organization, modified (globally or meter-by-meter), and then used for reporting. You can also adjust the budget globally by a specific amount or make global percentage adjustments, and then drill down meter-by-meter for fine-tuning.
Create budget scenarios (actual, best case, worst case) to forecast expected use, cost, and unit cost. Each budget can be adjusted to compensate for unexpected use, weather, rate increases, and other variables. EnergyCAP also provides use/cost vs. budget reports to make it easy to see how you’re doing month to month.
Rate schedules have a tremendous impact on energy costs, and EnergyCAP makes it easy for you to make sure you’re paying what you should be paying and that your tenants or internal customers are being charged appropriately.
Automated rate schedule benchmarking and specialized reports help you confirm that your accounts are all on the correct and most favorable rate schedule and identify savings opportunities. For internal chargeback or tenant rebilling scenarios, build custom rate schedules or add special charges (e.g., administrative fees) to pass-through vendor rates. And your actions can be tracked, analyzed, and communicated via EnergyCAP’s easy-to-understand reports.
