• A great part of the thermal energy coming from fuels is lost during industrial processes, and this is particularly evident in the case of an industrial furnace.

• "Temperatures are measured at different spots, and control the fuel injection, and production speed. Different temperature levels can be necessary to achieve the required process, which can be: melting, change of constitution, extraction of chemical compound, thermal treatment etc… Each process requires specific temperature conditions and processing time. In the case of batch process furnaces, preheating is necessary to bring the furnace to the right temperature. Often, the required time is over-estimated, and the furnaces spend stand-by time at the correct temperature but without the process running. "

• "In general, for industrial buildings the use of natural light is relatively rare. A higher use of natural light can increase the comfort and health of the employee. Moreover, with more openings or windows, the solar heat gain can be improved (resulting in fewer heating needs) and the electricity need for lamps reduced. Before implementing such a measure, the pros and contras have to be evaluated carefully. However, natural light use is dependent on time, season and weather. It is also spatially limited, can cause blinding and overheating in summer."

• Depending on the use of the room (e.g. production or warehouse), the daylight input (which changes during the day) and the human presence (when nobody is in the room the light is not used), the artificial light requirements and quality vary and in most cases can be optimised. In this fact sheet we consider all technical solutions for the regulation and control of lighting systems as lighting management systems. Constantly adapting the light to the needs allows generally interesting electricity savings.

• "In order to increase ""utilance"" (maintenance factor or room efficiency) and therefore reduce the need for light, the following efficiency measures can be implemented: • Replacement of luminaires: use new lighting systems with an adapted light intensity distribution and/or use luminaires that can be switched off instead of ceiling lamps. in general it is good to take into account two options: - Only change the bulb or tube: usually the bulb can be replaced directly with the LED. For tubes, the situation needs to be assessed more carefully, since tubes usually have a starter or ballast. In some cases, therefore, the ballast or starter must be short-circuited. Recently, LED tubes have appeared on the market and can directly replace old tubes (for example T5) with wireless HF ballast to replace or driver to change. - Change the entire equipment / lamp. • Changing the room configuration: Optimize the layout of the desks and use temporary partitions. Optimize the use of natural light. • Surface treatment: Choose reflective (white) furniture and/or repaint the surfaces."
