10 European organizations, one of which is Sestao Berri, have implemented TRIME (Trias Mores Energetica), an important pan-European project which intends to help social housing residents develop behaviour changes which enable them to save energy and money and at the same time live in a healthy environment. The initiative aims to support and advise more than 4,000 people living in social housing to achieve a 9% reduction in energy consumption per household and save up to 350 € a year on their electricity bills.
