Thermo-Hygral and Environmental Evaluation of Chosen Parts of an Ultra-Low-Energy Family Houses

摘要

The goal of this paper is to assess two ultra-low-energy family houses from thermohygral and environmental perspectives. Thermo-hygral evaluation, done in two-dimensional PC software Area, has shown results that consent with the newest standards for designing critical details in ultra-low-energy family houses. Both cases show correctness in design with regards to thermo-hygral 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 the roof structure with value of 3084 MJ in house A and 1943 MJ in house B. In terms of global warming potential indicator, the most emissions were calculated in the exterior walls of house B (593 kgCO_(2eq)/m~2). From the acidification potential, the most emissions were determined in the roof structure of house B (1.02283 kgSO_(2eq)/m~2).
