Long Time Testing of Temperature Parameters of Wooden Lightweight External Walls

Abstract

The article will present the partial knowledge of the area of thermal properties of the wooden lightweight external walls. The temperatures on the monitored samples of walls built in the air-conditioned room in the Laboratory of pavilion type for one week in cool, intermediate and warm periods will be shown. It will be described as the wall develops under the stationary conditions of the internal environment and the real conditions outside changed during the selected time period. Further differences in surface temperatures affected tone color design plaster used on the exterior facades will be followed. The thermal parameters of variant wall constructions, obtained under the steady state and non-steady thermal state and simulations will be compared.

Outdoor Climate Change Analysis in University Campus: Case Study with Heat-Air-Moisture Simulation

“…The station is equipped also with two pyranometers for measuring of short wave irradiation, one -Star Pyranometer FLA 628 S is on the horizontal plane. The other one on the vertical plane is not used in this case [9]. All devices are connected to the Almemo 2590 datalogger.…”

“…The University of Zilina Campus is since 2014 equipped with its own weather station, which results are analyzed in this paper as the climate parameters among the years and also in a case study with HAM simulation in WUFI Pro. Main reason for obtaining own weather station was to have as accurate outdoor climate for the lightweight wooden walls research as possible and the opportunity to conduct simulations [9,10]. Also another universities use own weather stations nowadays, to increase accuracy of comparison [11].…”

Usage of Raspberry Pi for Temperature and Relative Humidity Measurements and Comparison with HAM Simulation

“…Sections 1, 2, 4 and 5 are diffusional closed constructions and the 3 rd section is made as a diffusional open construction. More detailed description can be found in [5].…”

Measurement of Lightweight Experimental Wall and Comparison with Different Simulation Programs

“…More detailed descriptions of the wall fragments are mentioned in [1] and results from the long time testing are in [2]. Results of measured thermal conductivities are shown in [3].…”
