Assessing Energy Performance And Costs In Tennessee Fire Stations
The plots below show the distributions of annual energy use and energy cost intensities
at fire stations in a major city in Tennessee. The data used for these plots reflect energy use and cost data collected at Tennessee Fire Stations
for the fiscal year 2004.
To rate your Tennessee Fire Station using the plots, you will need:
Gross floor area of your fire station.
Total annual energy use for all fuels at your fire station (electricity, gas, etc.)
Total annual energy costs for all fuels at your fire station (electricity, gas, etc.)
For rating energy cost, calculate the annual energy cost intensity of your fire station by dividing total annual energy costs by the
gross floor area of your fire station ($/sqft). Enter the cost plot on the x-axis at your cost intensity. Read up to the
curve and then left to find your rating. The rating for your fire station corresponds to the percent of fire stations in Tennessee
that are more energy-cost-intensive than yours. The higher your rating, the better your fire station's energy cost performance.
For rating energy performance, calculate the annual source energy use intensity (EUI) of your fire station using the Total Source Energy Use Worksheet
available under "Benchmark Your Building" at this website. Enter the energy performance plot on the x-axis at your EUI value. Read up to the
curve and then left to find your rating. The rating for your fire station corresponds to the percent of fire stations in Tennessee
that are less efficient than yours. The higher your rating, the better your fire station's energy performance.
These tools can help you spot exceptional fire stations and at the other extreme, those fire stations that can most benefit from energy-related
improvements. Fire stations rating below 30 often have very large energy cost reduction potentials.
