With new energy directives in place, the Swedish Social Service (SSS) stands before the challenge how to reduce the energy demand in its locales. It is a complex matter, as the locales are rented from various property owners and it becomes a question of how to reduce the operational electricity and influence the property owners to work more with energy efficiency. This thesis takes a balanced research approach in three parts. Firstly a qualitative part in form of interviews with personnel at the SSS and its property owners, secondly a quantitative part of descriptive nature in form of energy statistics and thirdly a literature review of Energy Management (EM) Supply Chain Management(SCM), Green Supply Chain Management(GSCM) and Enviromental Performance Indicators (EPI). This in order to be able to give normative recommendations of how the SSS should act to reduce its energy consumption in its locales and provide new insights on how EM, SCM, GSCM and EPI can be applied in effect. The results show that the Swedish Social Service should act in the following areas to control its energy efficiency: statistics and follow-up, locale strategy and operational electricity. To get efficient statistical material the SSS should update their registers of property owners, update guidelines for energy statistics reporting and continue with the same collection method for data (e-mail survey) to get continuity. The literature review and interviews show that a segmentation of suppliers (property owners) based on factors like area in property, good relations, area of local and energy performance indicators should be useful as to know how to distribute resources to enable energy efficiency. Finally, the study shows that various locales has high rates of idling loads and have a energy saving potential of 10-15%.
