Energy scheme, typical approach
The typical approach to an accurate design of an energy scheme for a building is illustrated in the adjacent flow chart.
First of all, an energy scheme requires a catalog inclusive of data describing the building.
Verified data regarding occupancy are also important for a robust energy scheme.
The next step of an energy scheme is the determination of the energy demand and system capacities.
Appropriate and detailed calculation specifications or thermal building simulation are applied here.
An essential, central step in the energy scheme is the detailed optimization of both energy demand and performance requirements using the above-mentioned methods.
The analysis and evaluation of the already existing supply conditions are also important for an energy scheme.
The possible system schemes are taken into consideration inclusive of specific costs and efficiency factors.
Via operating and capital costs, the supply conditions and system parameters result in an assessment of the economic efficiency of the examined system schemes - the central aspect of an energy scheme.
Another aspect of an energy scheme is the identification of ecological consequences.
Economic efficiency and environmental contamination are assessed in the energy scheme in collaboration with the customer in the form of a cost-utility-analysis and thus, provide the basis for the investment decision.
