n 2016, the City of Belgrade joined the project "Accelerator of efficiency in pollution (BEA)" in cooperation with the United Nations Environment Program (UNEP) and the World Resources Institute (WRI) in Washington, in the implementation of which Prof. Dr. Miroslav Kopečni participated as a member of the coordination group.

The main goal of the BEA project is to develop and adopt a new City Policy in the field of energy efficiency in buildings, respecting the new Law on Housing and Building Maintenance. Other goals of the BEA project include defining procedures and measures for energy rehabilitation of public and private facilities, together with the development of a demonstration project that should indicate the practical application of the proposed measures. As a result of this project, a MANUAL ON ENERGY EFFICIENCY in residential buildings and houses has been developed, which you can view by clicking here.
