Achieving Energy Efficiency : Case study Saab AB, Järfälla

Sammanfattning: Today’s politics in Europe strongly encourages sustainable development within companies. Hence, it is important to raise awareness in rational use of the utilities, such as electrical energy or space heating within the buildings. Different opportunities on how to decrease the energy use within Saab AB facility are analysed in this research. Several energy efficiency measures are suggested in this thesis, together with an economical evaluation for some of the proposals. Humidity control can be quite difficult and expensive for factories or large areas. In smaller rooms or areas, it is possible to use portable humidifiers in order to raise the humidity levels in the room. To reduce the energy consumption for such systems it is important to consider if they are necessary and investigate if they work properly. This thesis focuses on the relation between ESD and relative humidity as well as how to prevent ESD from occurring. Also investigated in this research paper is the relationship between ESD and relative humidity levels since at Saab they are using humidifiers as a prevention technique for ESD. Electronic devices, circuit boards, components and data are highly sensitive to electronic discharge, therefore correct humidity levels are essential in order to reduce the damage caused by ESD. By controlling the humidity levels there is also the potential to reduce energy consumption in the building. This thesis also investigates other energy saving measures in order to reduce the overall energy consumption of the facility. An important finding in this thesis was the waste heat dissipated from the air compressors, in the basement, and how that heat can be recovered and repurposed.
