Turn Down City Hall Break Room Water Heater The 6 gallon water heater in the break room was heating water to 140 °F. Turned down to 120 °F Conserve 6-10% of water heating costs (EPA) Prevent burns

Unplug Appliances Except for refrigerators, unplug energy consumers that are not being used. They may consume energy even when turned off.

Museum Boiler Pipe Insulation Heat from the steam conducts onto the pipe and then conducts into the surrounding air Insulation will keep the heat in the steam Heat lost from the pipe can overheat an area, and waste energy Heat may not reach where it is needed because it dissipates into the air Insulation can reduce the energy lost from the system by 90% 2

Alliant Shared Savings Program A loan that is paid back with the energy savings over a maximum of 5 years 3% Administration Fee Can combine the City Hall and Museum projects for a larger contract amount It can be paid off early with no penalty Allows “shared savings” when the loan payment is less than the energy savings
