摘要

The goal of this paper is to assess two ultra-low-energy family houses from thermo-physical aspects and environmental perspectives. Thermo – physical evaluation, done in two-dimensional PC software Area, has shown results that consent with the newest standards for designing critical details in two ultra-low-energy family houses. Both cases show correctness in design in regards to thermo-physical properties. Both critical spots – corners are well insulated with surface temperatures over 17°C, which indicates low risk of mold occurring. Most of the embodied energy is in roof construction with value of 3084 MJ in house A and 1943 MJ in house B. In terms of indicator of global warming potential, most emissions were calculated in bearing walls of house B (593 kgCO_(2e)_(q)/m~(2)). From the acidification potential, the most emissions were determined in the roof construction B (1.02283 kgSO_(2eq)_(/)m~(2)). It can be stated that financial expenses on groundwork and preparing polystyrene casing for a reinforced concrete slab is significantly higher (family house A) than for foundation insulated from the exterior side with extruded polystyrene (family house B).
