To overcome this, the city of Aachen, together with the housing company, launched an intensive communication campaign, including the distribution of flyers in four different languages (German, English, Russian and Turkish), the organisation of information days for tenants before the renovation to inform them about the impact of the refurbishment work and the provision of information on the project on the boards located in the buildings’ halls. Additionally, energy consultants visited tenants to present them easy ways to save energy in their everyday life. Consultants also offered tailored advice to new tenants, who moved into the building after the renovation, to help them understanding the functioning of the new equipment.
In Aachen, the renovation of social housing buildings is a win-win situation: the comfort of tenants is increased, while the municipality is reducing its costs related to the support of low income families for the payment of their energy bills. To guarantee the return on investment however, experts in Aachen advise not to neglect the impact of tenants’ behaviour and to make sure to train the inhabitants to use energy efficiently.
