This paper presents the multivariate analysis of four designed systems of fire protection for multi-space underground car parking lot. The designed systems for 3563 m2 of parking covered: the standard fire hydrants, sprinklers (wet and dry) and nozzles. The proposed fire protection was assessed due to its cost-efficiency, reliability and technology. The financial assessment was based on dynamic generation costs (DGC), net present value (NPV) and benefit-cost ratio (BCR) determined after assessment of the investment as well as operation and maintenance costs. The reliability analysis was based on calculated readiness indicator while technological aspects were assessed according to i.e. speed of action, required volume of water, sensitivity to low temperatures, degree of automation and facilitation of fire-fighting action. Finally, all the developed indicators were applied to weight sum model method, allowing to select the most appropriate design in relation to its cost-efficiency, reliability and technology.
