The project Croatian Solar House (CSH) has a strategic value for the Croatian society and state due to its wide reaching solutions of the energy and environment problem in Croatia, which are technically feasible and economically practical. The goals of the CSH project are in total accordance with the strategic decisions of the EU toward the "sustainable development" on the way of the energy consumption rationalization, the essential ratio raiseof the pure renewable sources, as well by the CO2 and other pollutants reduction. Unlike the non-ambitious energy strategy, which could lead to the 70% energy import dependency of Croatia by the year 2030, the CSH project, through a wide range of planned constructive actions, demonstrates and proves the possibility of totally different approaches and strategies. Through the proposed solutions can be achieved the goals of the "sustainable development" atatining and an energy dependency as well as the CO2 emission reduction near the Kyoto protocol.
