In 2003, Delft adopted a Local Energy Action Plan with the aim of reducing CO2 emission and increasing the consumption of renewable energy. As a follow-up action of this plan, in 2003, Delft set up the Delft Climate Investment Fund (DCIF) including a budget of €12 million to invest in the built environment (e.g industrial buildings, office buildings, new housings, social housing companies, etc.). This fund was not including existing private residential buildings and there were no financial instruments available to private homeowners. For this reason, in 2006, the city council of Delft set up financial instruments with the aim of encouraging residents to invest in renewable energy and energy-saving measures: a revolving fund and a soft loan scheme.
