The Fraunhofer Institute for Industrial Mathematics (IWTM) has developed a software for the optimization of energy concepts for office buildings together with the project developer of solar systems Goldbeck. This Goldbeck Energy Optimization System (GEOS) can be used by planners and consultants in the future to calculate hundreds of energy scenarios in the shortest possible time and then use them to plan the energy supply and use in the building.
All energy flows taken into account
The software considers all energy flows in the house and compares them with the generators. The latter are not only solar systems. District heating and CHP plants with condensing boilers and district cooling are also included in the calculation. Investment, consumption and operating costs as well as savings in carbon dioxide emissions are also taken into account. These calculations are compared with a reference scenario. This in turn is the concept with the lowest investment costs. In this way, the planner can filter out the most economical concept over the service life.
In addition, the client gains more transparency in the decision-making process because the solution is presented in a way that is comprehensible to laypersons.
