Hopefully, you read through my past article (“Church Energy Improvements, Part One”) about the beginning of maximizing the energy usage of the Broad St. Church of Christ building. You saw some of the pictures and can deduce, probably like other church buildings you’ve been in, that things can be improved upon.
Recall that the building, located in western Georgia tolerates mild winters but takes a beating from brutal summers. How can we know that any continued church energy improvements help save us money? First we have to get some basic statistical data.
Continued Church Energy Improvements
A next logical step was to begin to analyze energy usage. Just as at most churches, I got in touch with the fellow who pays the bills. He gave me the 2012 calendar year’s bills. With just a basic spreadsheet application, I computed a few pieces of information:
- On average, the BSCOC uses 10,475.15 kWh/month. This brings the electricity portion of the bill to $1,413.89 (on average) per month.
- Including gas ovens and gas heat, the building uses (on average) 80.54 CCF per month at an average cost of $96.75.
- If we take our 12 month electricity usage and divide that by our approximated square-footage (37,000 sq. ft.), then we have (on average) 3.44 kWh/sq.ft. These numbers are only about 1% higher than the national average according to one resource .
Some basic statistics were easily computed using a simple spreadsheet and by simply looking at our previous bills. What will come next? Continue on to Energy Maximization of a Church Building, Part Three.
