Worldwide energy prices have indeed increased dramatically. In line with this, numerous environmental efforts are also being implemented following the alarming environmental decline. Numerous organizations are now conceptualizing different ways on how to lower down energy consumption and help alleviate excessive carbon emission. With Africa being the second largest continent, African industries should find ways on how they can decrease their energy consumption.
They should start with lighting
One of the easiest ways to lower down energy cost is through enhanced lighting efficiency. One way to start is by choosing the most efficient yet less expensive type of light.
When it comes to energy efficiency, Compact Fluorescent Lamps or CFLs top the list. Studies show that CFLs outcompetes incandescent bulbs to as much as 4 percent in terms of energy efficiency. They even last 12 times longer than ordinary incandescent bulbs. Indoor CFLs should also be adjustable based on the workers’ needs. It is also a huge advantage if the workplace is specifically designed to be naturally lit. If not, placing work stations near the windows for natural lighting is also a good option. It is also important to install occupancy sensors that will make the lights turn off if a room is unoccupied.
For outdoor lighting, companies should consider installing a light timer so that all outdoor CFLs will automatically shut down during daylight.
Increase motor efficiency
Choosing a right industrial motor is almost the same as choosing CFL over incandescent bulbs – energy efficiency should be the deciding factor. Replacing inefficient motors with their premium counterparts will definitely result to a huge cut on energy cost. Though the premium ones are almost 20 percent costlier, the benefits they offer outcompetes the less efficient ones. For motor power transmission, choosing synchronous belts over V-Belts should also be prioritized. That’s because V-Belts tend to slip and deteriorate that result to lesser energy efficiency at maximum loads.
Air compression
For facilities that require compressed air to operate, air compressors take up to 10 percent on the company’s energy cost. Companies should start with routine maintenance. Fixing leaks alone will help decrease energy cost on a larger scale. To eradicate unnecessary uses, companies should implement a policy that will regulate or manage compressed air usage. To enhance the performance, air compressors should be performed with controls based on a specific required rate.
Heating, Ventilation and Air Conditioning
Heating, Ventilation and Air Conditioning or HVAC takes up 30 percent of a company’s energy cost. Controlling the temperature based on the required level is the main key to this. Having an inappropriate level of temperature in a workplace can only contribute more to a bloated energy cost. Setting up zones where exhaust fans will shut down if not needed is also a way to enhance energy efficiency.
Cut cost on refrigeration
Cutting cost on refrigeration is not only beneficial to the company itself, it also directly contributes to environment conservation by reducing harmful carbon emissions. Regular maintenance is a good way to start. Other than that, making sure that the temperature settings are not lower than what is required. Making use of an air curtain technology is also advisable as it seals in cold air produced by the refrigeration system. Less cold air coming out means lesser energy the system requires to operate.
