At work

You should know the power capacity you have contracted and whether it truly matches the needs of your business. Contracting more power than necessary results in unnecessary expenses.
Check your electricity bill to see whether the reactive power surcharge is between –3.3% and –3.7%. If it falls outside these values, the electricity provider will apply an additional charge. To prevent this, you can install capacitor banks, which reduce this type of energy.
Look into the different electricity tariffs that may fit your consumption schedules.

Low-energy bulbs allow for overall savings of up to 80%. New-generation fluorescent tubes consume 80% less energy than incandescent bulbs and last up to 10 times longer.
Replacing electromagnetic ballasts with electronic ballasts in fluorescent tubes results in a 10% energy saving and extends tube life by up to 50%. It also increases light output by 15%.
Install motion detectors in areas with intermittent use.
Regulating the light output of luminaires according to the amount of natural light coming from outside—using photocells—helps reduce energy consumption.
Use a lighting control system to manage the required light levels in each space, schedule switching on and off, etc., to achieve greater savings.
Avoid halogen lamps whenever possible, replacing them with compact fluorescent lamps. This will save about 60% energy.
LED lamps are very useful for ambient lighting and consume a minimal amount of energy.

Under winter conditions, an indoor temperature of 19–20ºC is sufficient to achieve good comfort. In summer, this level of comfort is reached at around 25ºC.
For every degree the heating or cooling is increased, energy consumption rises by 8%.
Optimize industrial processes to reduce the cost associated with repeated switching on and off.
Proper maintenance of equipment and machinery prevents breakdowns and low performance.
New technologies are more efficient—check whether it is worthwhile to upgrade your equipment.
Turn off electronic devices at the end of the working day and when you leave for lunch.
Avoid using screensavers, as they increase the energy consumption of computer equipment. It is better to configure devices to enter “sleep mode” after a set period of inactivity, or to use a “Blank Screen” screensaver.
LCD monitors, in addition to offering better performance and design, consume much less energy than traditional CRT monitors.

If you are considering renewing your company’s computer equipment, it may be worthwhile to find out which brands and devices are designed to be recycled (up to 95%). Recycling not only helps keep the environment clean, but also reduces the energy required to manufacture new equipment.
If your workload allows it, opt for multifunction devices, as you will save energy by using a single machine instead of, for example, a fax, printer, scanner and photocopier.
Minimize the use of battery-powered devices (such as wireless mice, etc.), as battery manufacturing requires high energy consumption and batteries are highly polluting.
Document printing is one of the most expensive and polluting processes in an office. This is not only because we consume a lot of energy and paper, but also because it generates waste such as toner and cartridges, which are costly and difficult to recycle. Consider implementing a “paperless office,” giving priority to electronic documentation over printed materials.
To accurately determine your company’s savings potential, consult a professional to carry out an energy efficiency study.
