Caring for Equipment

Congregations that understand their energy consumption are better equipped to improve upon its efficiency.
Improving energy efficiency can provide an estimated $avings of 25 percent as well as:
  • Save money that can be redirected to the basic faith-based mission
  • Extend the useful lifespan of your worship facility and its equipment
  • Conserve natural resources for future generations
  • Improve the overall comfort and appearance of your worship space
  • Increase security and safety

Space Heating

Heating systems are the single largest energy cost for most places of worship. Many techniques and fuels are available for heating your worship space and rooms. All systems have supporting equipment such as thermostats, pipes and ducts, which provide opportunities for saving energy.

Boilers are vulnerable to breakdown from low water conditions that result from poor maintenance and when controls intended to prevent the problem do not work properly.

Energy Savings Tips

Monitor the boiler-water quality. Boiler waterside scale acts as an insulator thereby preventing heat transfer from the fire to waterside. As little as 1/32 inches of scale increases fuel consumption by as much as 7 percent.

Space Cooling

No matter what kind of cooling system you have in your place of worship, you can save money and increase your comfort by properly maintaining and/or upgrading equipment. You may be able to cut energy use by 10 to 50 percent.

Cooling equipment is essential, especially during summer months, when it must work harder to cool large open spaces filled with many people. The compressor is often the component that breaks down and can be expensive to replace.

Air Conditioning Calculators 
Energy Savings Tips

An Energy Management System can reduce energy usage 10 to 30 percent. This reduction is achieved by limiting air conditioning operation during unoccupied hours.


Lighting systems can account for up to 40 percent of the total energy costs for a place of worship. In addition to supplying necessary lighting, all lighting systems produce heat. Lighting produced heat is the primary source of heat gain inside a building and presents a considerable added load to the air conditioning system. An energy efficient lighting system can save as much as 30 to 50 percent of lighting energy, plus 10 to 20 percent of cooling energy.
Energy Savings Tips

Replace fluorescent T-12 fixture/lamps (1.5” diameter) with T-8 fluorescent fixtures/lamps (1” diameter). T-8 lamps typically use 40 percent fewer watts and produce 40 percent less heat. This is important in warmer months when air conditioning is needed.

Water Heating

Whether heating water for activities in places of workship, restrooms or for the kitchen, it is important to have enough hot water of the correct temperature to meet your needs. Water heating is a large energy expense, accounting for about 4 percent of your utility bills. Reduce your water heating bills by taking just a few low-cost, energy-saving steps.

Lowering your hot water heating systems' energy consumption can mean big dollar savings, while reducing your potential for equipment failure which could result in interruption of activities and services.

Inspect all hot water lines and tanks to be sure that they are insulated.


The ventilation system’s function in a place of worship is to control temperature and humidity for space comfort, and control indoor air quality. While heating and cooling are seasonal, a forced air ventilation system is operated throughout the year. Without proper attention, a significant amount of your energy dollars may end up on the wrong side of the exhaust fan.

Running a fan at its required speed will save on electricity costs. A 10 percent reduction in fan speed can result in a 30 percent reduction in power requirements.

Energy Savings Tips

Periodically inspect ducts to verify that all insulation is intact and adequate. A tight and well insulated duct system can easily prevent 20-25 percent energy waste.


Places of worship increasingly rely on their electrical distribution system to support their mission. They use highly sophisticated electrical equipment including office equipment, and complex organs and sound systems. These systems are prone to damage from electrical surge or other transients. When these electronic systems malfunction, it can impact worship services and require costly repairs or replacement.

A properly maintained electrical distribution system will reduce electrical energy usage, equipment failures, and unbudgeted expenditures.

Energy Savings Tips

Computers and other electronic equipment use electricity around the clock, even when not in use. Encourage employees to turn off all office equipment after hours and on weekends. Turn off lights, computers, monitors, printers and copiers at the end of each working day and ensure they’re not just in sleep mode.

Cooking and Refrigeration

Kitchens in places of worship are a major energy consumption area. Energy is used to power cooking equipment, refrigerate food, and heat water. However, these areas can offer significant cost savings without compromising hygiene or resources.

The use of Variable Frequency Drives(VFDs) in today’s exhaust hoods can result in up to 50 percent energy savings compared to standard exhaust hood installations. See how VFDs can improve the energy efficiency of many types of motor-driven equipment.
