This case study focuses on the implementation of the Green Energy Train programme in apartment buildings in The Hague between September 2001 and May 2003. It targeted 228 households in eight apartment blocks. The project aimed at reducing the energy, heat and water use of these households with 5%. This target was not reached due to several reasons. The most important ‘indicators of failure’ were problems with monitoring (heating savings could not be measured), the used education and information materials (too philosophical for the target group), no alignment with a planned renovation and not enough knowledge about the target group and their relation with the housing association Vestia at the start of the project.
Although the primary goal of the project was not reached, many secondary goals of the different project partners have been reached (method has been tested, inhabitants got better relation with Vestia, lasting behav-ioural changes have been achieved, people have been educated, living environment of target group has been improved, etc).
The Green Energy Train was based on the philosophy of ‘Leve Energie’ (Live Energy) that builds upon the energy in the five elements (earth, water, fire, air and ether) and the four different levels of energy within these elements (individual body, in house, direct environment, rest of the world). The communication and education materials were based on these categorization and general idea about energy. The method is demand driven. This means that the education and information materials are adapted to the demands of the target group.
