This public domain online calculator for solar district heating (SDH) systems is available for interested market actors as an easy accessible and user-friendly calculation program for a first dimensioning and forecast of performance and economical values for solar district heating systems.
The calculator was developed based on numerous and detailed dynamic system simulations with the simulation program TRNSYS and under consideration of a large number of influencing factors. Calculations are possible for the distributed and centralised system concepts listed in the selection box.
The Online-Calculator has been developed in cooperation with Solites, a German research institute for solar and sustainable thermal energy systems within the Steinbeis Foundation, and AGFW, a German professional association promoting the development and expansion of combined heat and power (CHP) and district heating and cooling systems, with the support of the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety.
It is made public in the framework of the Intelligent Energy Europe 'SDHtakeoff - Solar District Heating in Europe' and 'SDHplus - New Business Opportunities for Solar District Heating and Cooling' projects.
