The current activities on European and national level focus mostly on the residential sector, ignoring the potential impact on already existing infrastructure of Automatic Meter Reading (AMR) and energy management systems having achieved savings for over a decade especially by municipalities leading by example. Around 34% of energy used in buildings is consumed in the non-residential sector. German communities consumed 127.7 petajoule in 2013 of which ¾ where for heat with the share for electricity continuously increasing. In total, cost for energy amount to 4 billion Euro every year.
The use of new technologies to save energy is a challenge. Both internal building users (office staff, teachers or museum staff) and external building users (office visitors, hospital patients, museum visitors) must be convinced in order to achieve long-term changes in behaviour and therefore success. According to the authors, the perception of change by individuals plays a major role. Initial reactions to new developments are often rejection and denial. However, appropriate tools such as individual support and targeted training can help to persuade citizens to adopt new technologies. After an "As-is analysis", appropriate measures should be developed for the respective building users. These include, for example, the use of a logo for a high recognition value and workshops to disseminate knowledge. According to the authors, such a framework strategy can contribute to the successful engagement of various stakeholders.
