Cost calculation is particularly important in the case of environmental investments.
Purchase and assembly equipment for the acquisition of alternative energy sources have of course a positive impact on the environment. However, must also bring economic benefits for a potential investor. Currently used methods In Poland for estimating costs lead mainly to overestimations. Such cost estimations made deterrent investors from the use of e.g. solar collectors. The purpose of this article is an attempt to improve the initial estimates of the investor. The author proposed an algorithm that designates the investment cost of purchasing and installing e.g. of solar collectors based on market prices. In order to increase the accuracy of calculation was used CBR. Case Based Reasoning is a method of solving the problems, which are not restricted to generalized knowledge, but able to use specific knowledge contained in occurred cases. In Article will be presented workflow and calculation example showing the use of CBR in the calculation of the costs of environmental investments.

Keywords: cost estimating, case based reasoning, solar installation cost.
