Energy Saving Ordinance (EnEV)
EnEV set minimum requirements for the energy-related quality of the building shell and the system technology for both new and renovations of existing residential and non-residential buildings. These requirements are updated to enhance their stringency.
Renewable Energies Heating Act
The Act mandates use of renewable energy sources to provide heating and cooling in both residential and nonresidential buildings, whether new or existing. The government supports the act through capital grants for smaller systems and low interest loans or redemption grants for larger systems.
Act on the Promotion of Renewable Thermal Energy (EEWärmeG)
EEWarmeG imposes the use of renewable energies, including solar heating systems and heat pumps, in the construction of new buildings (so-called obligation to use)
Market Incentive Programme for Promotion of the Use of Renewable Energies (MAP)
Program is primarily for existing buildings, and the federal government supports grants and subsidies for heat pumps, biogas systems, and solar energy systems. KfW, the government bank, supports low interest finance usually for larger solar energy systems.
KfW Funding Programs
KfW has funding programs for both new and existing energy efficient buildings. Energy performance of buildings is evaluated against standards set by EnEV. Amount of loan is directly proportional to percentage of improvement in energy efficiency of building under consideration over the baseline set by EnEV.
