Exit Signs Can Be Energy Hogs

Pastors Tyler and Neal "basking in the glow" of the exit signs

Exit signs are just not something you think about, but exit signs run continually…that’s 365 days a year, 24 hours per day or 8760 hours a year.

Jonesville UMC’s energy audit recommended a simple, but effective way to save energy and money: change their exit signs from regular light bulbs (2 – 25 watt bulbs per sign) to LEDs (1 watt each).

Jonesville had 20 exit signs throughout the church, so this simple change was equivalent to turning off 19-50 watt bulbs. The change was as simple as unscrewing the old bulb and screwing in the new and took all of 2 hours to do the entire church!

This one simple change has a big energy stewardship impact:

  • fewer problems for people with asthma – prevents the emission of about 9 pounds of nitrogen oxide, the main ingredient in ozone or smog, which is especially harmful to people with asthma;
  • less acid rain – prevents the emission of about 27 pounds of sulfur dioxide, which causes acid rain; and
  • less mercury pollution – especially damaging to pregnant women and children
  • prevents global warming – prevents the emission of about 7 tons of carbon dioxide, the principal global warming gas.

And this translates to an annual saving of $900 a year – this year and EVERY YEAR FROM NOW ON!

They’re also labor-saving: the LEDs have a lifetime of 100,000 hours…therefore the next change is in 2015.

The cost of the LEDs was $12 each or a total of $240. And as a result of taking action on this recommendation, NYSERDA reimbursed Jonesville for the entire $200 cost of the Energy Audit (the cost of which has since been reduced). This is just one of seven cost-effective measures identified by the Energy Audit.
