The document describes the MARIE project consortium, which includes 23 partners from 9 Mediterranean countries working to develop the Mediterranean Building Energy Efficiency Improvement Strategy (MEDBEES). The consortium is led by the Government of Catalonia and includes various regional governments, universities, and agencies. The goal of MEDBEES is to identify barriers to improving energy efficiency in buildings in the Mediterranean region and develop measures and pilot projects to help overcome these barriers in order to meet EU energy targets by 2020.
