Abstract The analysis is based on the results of computer simulation by using DesignBUILDER software. In multi dwelling house assessed. There are standard building constructions used like as brick wall with polystyrene thermal insulation, Windows plastic frame and double glazing flat roof insulation from without gravel layer. this considered so called green walls, that localized at eastern, sou...

Thermal and energy dynamic analysis of buildings is a well-established procedure to evaluate the effective building energy performance, considering real climate. The proposal of new technical solutions and innovative strategies to be applied for both summer and winter period has a fundamental role also considering the IPCC suggestions and the EPBD European Directive implementation. In this pape...

Moisture inside the footwear can considerably affect the thermal insulation. In this study with a thermal foot model there was simulated three sweat rates (3, 5 and 10 g/h). Five types of footwear with various insulation levels (dry insulation from 0.19 to 0.50 m2. K/W) were tested. The footwear insulation reduction was calculated for 1.5 hour period. The reduction in insulation was related to ...
