Behind the Numbers

  Data were uploaded for each building by month from August 2018 – January 2020. Goals are measured using 12-month rolling totals. Values in Green Data Sheets can be used for qualitative comparisons and evaluating trends. The Dashboard values are used for District-wide goal tracking.  

Energy

Energy Star is an energy efficiency rating program created by the United States Environmental Protection Agency. It provides a rating from 1 to 100 that is based on a building’s utility (primarily electricity and natural gas for most schools) data and building characteristics. The rating reflects how energy efficient a building is compared to similar buildings over a 12-month rolling period. Higher scores are better, and a score of 75 or higher makes a K–12 school eligible to apply for the Energy Star award.  

Water

The consumption amounts are the total amount of water used at a school– both indoor and irrigation use. The graph illustrates the amount of gallons used per occupant (staff + students) over a 12-month rolling period.  

Materials

The hauler provides invoices that indicate how many times each month they empty waste and recycling containers at each site. The waste and recycling volumes are calculated based on the size, in cubic yards, of the container (landfill and recycling) and the number of times each dumpster or bin is emptied each month. For Kearney High School, the data reflects actual weights. The graphs indicate the percentage of the waste stream that is being recycled (diversion rate) over a 12-month rolling period.

Electricity

The data shown reflect electricity usage by calendar month, not weather-normalized. Data are shown in kBtu for comparison with natural gas.
