(2) Economic feasibility means achieving a simple return on investment in an alternative energy supply system shorter than its lifetime (8). In the case of a thermal energy supply system, the economic feasibility of that alternative system is to achieve a simple return period for investment in a new non-alternative energy supply system that is or is to be used in the building longer than the lifetime of this new non-alternative energy supply system.
