Make Time for Energy Savings

Turning off lights and equipment when they're not in use is one of the most cost-effective ways to conserve energy and save money. Unfortunately, building schedules can be complicated, and it's often difficult to get staff to cooperate. Electronic programmable time controllers optimize energy savings while maintaining comfort and convenience.

Time control features and options

A variety of electronic time controls are available; they range from basic, wall-mounted time switches to multi-channel time clocks with a variety of scheduling options. Some control programs include features similar to an energy management system.

In settings where occupancy sensors are not practical, simple time switches can be used to turn equipment off at preset time intervals. They are convenient to use and offer functional advantages over traditional twist-dial timers.

Multi-channel time clocks are a good choice for controlling numerous devices. Look for the following features:

•    Scheduling flexibility. The number of programmable switching cycles varies with each system, but most allow precise time settings as well as weekly and daily scheduling options. Look for units that reset automatically for daylight saving time and leap year.

•    Advanced warning. Time clocks with this feature sound alarms or flash lights before selected equipment is started.

•    Override. It's important to be able to override the timing system if equipment starts quickly or unexpectedly.

•    Power backup. A power outage can throw off a carefully planned system of timing controls. Make sure the system includes reliable backup power, such as batteries or capacitors.

•    Durability. Wear and tear on electronic controls can reduce their effectiveness or cause them to fail. Locate them in areas where they will be safe from damage or temperature extremes.

Electronic timers range in price from less than $100 to more than $1,000, depending on the type of device, and the features offered. No matter what type of system you choose, time controls are a simple and cost-effective way to reduce energy consumption.
