This article examines some methods for renewable power resources for Slovakia – solar energy, water-power, wind-power, biomass, geothermal energy. Exploitation of geothermal waters from architectural point of view, solutions of thermo pumps exploiting earth heat, etc., usage of non-conventional power resources and their application in low-energy objects. The energy efficiency of affordable homes must necessarily rely upon more basic approaches to design and construction. The arrangement for active utilization of alternative resources cooperates, to great extent, spatially with the construction of a house. Passive exploitation of natural power source then has direct and substantial influence over the disposition of the house, its cubic make-up and general conceptual solution.
