HAM Analysis of Selected Wooden-Framed Walls

Abstract

In this paper, heat and moisture regime of the selected wooden-framed walls is analyzed. This walls meet the nearly-zero energy buildings recommendations. Totally, there are seven different compositions. They differ with thermal insulation (such as mineral wool, phenolic foam, sheep wool, etc.) and outer surface (coating, aerated cladding). The fragments are installed in two air conditioned rooms. This enables the possibility to maintain indoor boundary climate conditions constant or change dynamically. The outdoor climate is real, one of the wall faces east and one towards the south. Each fragment contains several sensors: Thermocouple, relative humidity, both through the composition on contact with different materials and heat flow on inner surface. It is pavilion type of measurement and results can be interpreted for a whole climate season. Based on the measurements it is possible to calibrate the numerical model and set-up non-steady simulations. Conclusion about coupled heat-moisture transport through fragments will be made further.
