Saving Energy Dollars in Church

Since most houses of worship rely on small or non-existent budgets for capital projects, low- or no-cost measures that reduce energy consumption generally produce the best results.
 
Some simple steps involve changing the way congregant and staff use the building. Big-ticket items, such as replacing heating and cooling systems with more energy-efficient units, may not be practical until existing equipment reaches the end of its useful life.
 
A comprehensive energy audit  remains the best way to identify cost-effective efficiency improvements in a church. Below are some suggestions for reducing energy consumption:

Turn off lights when not in use.While occupancy sensors can be cost-effective, posting reminders to ensure that lights are turned off often does the trick. Timers are useful in lobbies, entries, and vestibules to ensure that lights stay off during daylight hours.

Replace incandescent light bulbs with compact fluorescent light bulbs (CFLs).

Unplug microwaves, computers,and televisions not in use that continue to draw power even when turned off.  

Heat and cool during occupied hours only. Make sure heating and cooling controls are set at minimum levels or are switched off during periods of no use.

Turn down water heater thermostats. Bathrooms and kitchens used primarily during worship services are good targets for lowering water temperatures.

Change filters.Filters should be changed on a monthly basis—more often if the congregation is located next to a highway or construction site.

Clean condenser coils. Condenser coils should be washed thoroughly at the beginning and end of the cooling season.

Check cabinet panels quarterly.Ensure that panels to rooftop
 air-conditioning units are attached with all screws in place,and make sure gaskets are intact to prevent air leaks.

Direct airflow. Close registers in any unused rooms to direct air where it is needed. If some rooms overheat while others are too cool,call a qualified heating and cooling contractor.

Close vents. In place of air conditioning, many older buildings have natural ventilation systems to remove hot air in the summer. Be sure to close these vents in the winter.

Seal gaps. Use caulk and weather stripping to seal gaps around windows, doors, chimneys, and other structural elements, including the foundation.

Insulate hot water pipes with pipe insulation. Fix leaky faucets, shower heads, pipes, and toilets.
