Energy Audits for Conservation


Clock Controls and Programmable Thermostats


Programming your equipment to run only when it is needed is one of the most powerful techniques for energy conservation. Coupled with this is the ability to turn off equipment when it is not required.


There are three main steps in achieving effective and long-lasting clock control, which area; (1) select clock controls that are flexible enough to perform all foreseeable tasks required, (2) provide clear and succinct instructions to that employees and staff can set and adjust controls as required, (3) install equipment that allows for un-scheduled use or equipment without causing complete reprogramming.


Electronic time clocks have overcome most of the shortcomings of the mechanical devices which are now considered obsolete. Electronic time clocks allow for a variety of different schedules, even allowing for holiday scheduling.


Cycling of circuits can be used to combine equipment use with Electricity Pricing schedules allowing only a limited number of units to run at a given time.  Air conditioning is one use of controlling units to ensure that units are not running simultaneously.


Timers are rated by the amount of amperage that they control.  This is the amount of amperage that they directly control and does not limit the amount they control by means of secondary switching devices.


Electronic timers typically have a battery backup that in event of power failures can keep operating for periods up to several months. Capacitors can also be used for time clocks that would only require backup for short periods. The advantage of the capacitor is that it should last for the life span of control. Batteries will require replacement and if battery failure occurs unit would have to be completely reprogrammed.


These controls should be available in area of use, full documentation on use of unit and staff and maintenance people made aware of purpose and setting of units.
