Abstract
Selecting a suitable heating and cooling system for a building is critical, because it impacts its life cycle cost. The aim of the article is to obtain an answer on the optimal solution in terms of economic efficiency of heat pump heating and cooling systems, since the initial investment in these systems is higher, but the subsequent costs during the period of use are reduced. Cost savings in the operation of heat pump heating and cooling systems is directly related to lowering energy consumption and reducing greenhouse gas emissions. In this study the economic analysis was carried out using life cycle cost method. Economic parameters used in the study include 3.75% discount rate, 1% escalation price rate, 20 years lifespan and 0,2369 €/kWh electricity price.
