General information
SolarEDA+ (Solar Easy District Analysis Plus) is a calculator for the economic viability to assess solar local heat systems for the provision of quarters. The specific production costs of technologies free production site according to the full cost approach of VDI 2067 provide the parameter for the economic viability of local heat systems. SolarEDA+ thus allows a comparative assessment of the economic viability of different local heat systems. The assessment ratio specific heat supply costs have been additionally introduced in order to take into account the investments in the heat distribution network. Furthermore, SolarEDA+ provides information on the technology input, the final energy consumption and the CO2-emissions for each local heat system.
Development and technical information
SolarEDA+ has been developed within the joint research project SolnetBW II - Solare Wärmenetze für Baden-Württemberg at IER. It has been developed from the EDA-Tool1,2 in Visual Basic for Applications (VBA). You can find further information on the development and on the project in the final report.
