To achieve a sustainable reduction of carbon dioxide emissions diverse solutions have to be considered. Besides technical solutions the promotion of energy efficient behavior may lead to a significant reduction of emissions. For public buildings the potential that lies in a more efficient energy behavior is assumed to range from 5 to 15% of the total energy consumption of a building (e.g. for schools or administrative buildings).
In order to tap this potential, the inter- and transdisciplinary project “change” has been set up. It is supported by the German Federal Ministry of Education and Research (BMBF). Its objective is to develop an internet based consultancy tool for public buildings. The project combines the expertise of environmental psychology and engineering with the practical knowledge and networking activities of a central consulting organization for institutions of higher education (HIS). As a first step an intervention program, based on calculated potential energy savings and on a set of target-shaped intervention techniques, has been designed and evaluated in cooperation with four German universities. First results will be presented.
