Planning Tool Compares Combinations of Energy Producers
Together with the Goldbeck company, we have developed a planning tool for this problem.
Depending on different key data such as:
- the cubature (volume of a building, regardless of its design or material)
- type of use
- location-specific climatic conditions
it compares meaningful combinations of energy producers with regard to different key figures. These are especially investment and operating costs, but also the expected CO2 emissions or the comfort of the cooling system.
Software Already Helps in Early Phase of Decisions
The resulting software offers the builder comprehensive multi-criteria decision support. The user can consider different variants in relation to the aforementioned factors against each other and receives in particular estimates for the amortization times of solutions with high investment but lower energy consumption in operation. In other words, the processes in which initial expenses for a property are covered by the resulting income.
A simulation forms the basis for determining the key figures. This simulates the coverage of location- and building-specific heating and cooling needs as well as electricity generation and consumption for the different producer combinations over a period of one year. How detailed the simulation is depends mainly on the amount of available information at the early planning phase in which the decision on the energy concept is made. This is where the planning tool differs from the building simulation tools that are already available on the market, which usually require data about the building that is only available in a very advanced planning phase.
