Sem Oxenaar uses his extensive knowledge of EU energy and buildings policy to support RAP’s work on energy efficiency and clean heat in Europe. Focusing primarily on district heating, heat planning, and energy communities.
Before joining RAP in 2022, he worked for REScoop.eu — the European federation of citizen energy cooperatives — gaining on-the-ground experience in working with energy cooperatives, supporting the development of citizen-led building renovation programs and clean heating solutions. In this role Oxenaar advocated on behalf of energy communities and cooperatives in Europe with the EU institutions.
