Lighting system consist of non-led lamps such as (from lower to higher efficacy): • Light-bulbs • Halogen-lamps • Fluorescent lamp In general, for the same illumination intensity, LEDs consume less energy than those lamps. Replacing the old lamps by LED allows reducing the energy consumption from 10 % to more than 50 %. Moreover, if useful lumens (or luminaire efficiency), which describes the amount of light emitted in the relevant target area (lm/W describes the total amount of light emitted by the bulb in all directions) are considered, LED lamps have even higher efficiency than other lamps which emits generally light for 360° and hence, only a smaller part of the light in the wrong direction can be reflected.

"The indoor microclimate and comfort not only increase energy efficiency but also affect the well-being and health of employees, which are key factors in increasing teamproductivity. In order to have greater energy efficiency it is possible to make changes and improvements in different fields: • Lighting • Ventilation and air conditioning • Heating • Kitchenette and bathroom facilities "

"The use of green IT devices concerns the application of energy-efficient computers, monitors, printers, photocopiers and telecommunications devices. We must not only consider their purchase, but also their efficient use: • Evaluate the current situation through an inventory of the devices used, including size and time of use on the power grid. Evaluate the energy consumption of individual devices to optimize their use or consider a reasonable replacement. • Buy smart meters to identify users who use too much energy or unnecessary loads (for example old inefficient monitors) and to have an overview of their energy consumption at all times • Purchase removable plugs to avoid stand-by • Centralize office equipment on a network so that multiple employees can use them • Virtualize corporate servers • Check the server room using cooled shelves. • Automate the processes of IT devices, such as backups. This allows processes to take place when the system has free capacity and thus to make efficient use of resources Optimize the management of data and files in your company • Small computers are sufficient for using office programs, sending e-mails, surfing the web. Thin clients are even cheaper. They are computers equipped only with a monitor, keyboard, mouse and headphones. Advantages: very low energy consumption, easy management and hardware savings because the software and storage are located on the server, reasons that usually lead to the purchase of new computers, when the old ones become too slow and their software is no longer compatible with the new updates. Consider replacing old devices with newer, more efficient components like SSD hard drives, rather than buying new computers • It is more sustainable to use a multi-purpose device for scanning, faxing and photocopying rather than one for each of these activities. • Choose the right printer. Today, most offices use laser printers. • Buy devices if they need to be replaced (monitors, computers, servers, fax machines, etc.) classified A and also consider the energy consumption especially of devices that cannot be turned off. Some good practices to adopt at the office: Use switchable outlets, switch off computers for breaks longer than 30 minutes (e.g. meetings or lunch breaks), switch off printers and photocopiers at night and on weekends, do not use screensavers, activate power management, disconnect chargers (phones, tablets). In the meeting room, LED videos should be used instead of beamers. Consider using a workstation for multiple employees. Employees can also use laptops for work from home and share other devices or equipment. Motivate your team. Let employees make suggestions for improvement, collect them, reward them when they are successful. Form energy teams and walk through the office and measure single devices using energy meters to detect energy waste. Use materials like stickers, flyers or reminders on the intranet. Inform on successes. "

"With the exception of control electronics, if available, the consumption of electrical drives is zero when they are stopped. Therefore it is important to stop a pump when there is no need. • Continuous flows without link to the user need Nevertheless, sometimes, a minimum flow rate is necessary in order to • maintain a given temperature on users, • avoid the formation of a biological deposit/film. The question is more difficult when determining whether to operate at reduced speed or stop frequently. The choice in these cases is often not only related to energy aspects but also to effect on a process or on maintenance. "

"In many pumping systems, the flow and pressure level are above the real needs. In cooling loops for example, the temperature difference between flow and return is too small. It shows that the heat exchange is poor and the flow rate is too high. Consequences are: • Over-consumption of pumps • Unnecessary cold production Flow rate is often not really controlled in users and could be reduced without negative impact on them. In order to maintain network temperatures, three-way valves are installed with a significant “leakage” rate. Another common problem is an unnecessarily high level of pressure. The high pressure at the pump discharge is then lowered in valves before reaching the users. It results in pure energy loss."
