EWärmeG
With the EWärmeG, the state of Baden-Württemberg passed the first state law of its kind in Germany in 2007. It came into force at the beginning of 2008 with the aim of increasing the share of renewable energies in the heat supply and making a contribution to climate protection and air pollution control through the resulting reduction in greenhouse gas emissions. An amendment to the EWärmeG was adopted in 2015 and came into force on 1 July 2015. The amended EWärmeG stipulates that in the event of a replacement heating system (or a retrospective replacement installation) in existing residential and non-residential buildings 15 % of the heat energy demand must be covered by renewable energies or equivalent replacement measures must be provided.
The Ministry of the Environment has commissioned a consortium consisting of ifeu - Institute for Energy and Environmental Research, Öko-Institut, Fraunhofer ISI and ECONSULT Lambrecht Jungmann Partnerschaft to evaluate the Renewable Heat Act.
