Intention, Principle, Outputs and Aims of the Experimental Pavilion Research of Building Envelopes Including Windows for Wooden Buildings

Abstract

The aim of experimental research in the area of exterior walls and windows suitable for wooden buildings was to build special pavilion laboratories. These laboratories are ideally isolated from the surrounding environment, airtight and controlled by the constant internal climate. The principle of experimental research is measuring and recording of required physical parameters (e.g. temperature or relative humidity). This is done in layers of experimental fragment sections in the direction from exterior to interior, as well as in critical places by stable interior and real exterior climatic conditions. The outputs are evaluations of experimental structures behaviour during the specified time period, possibly during the whole year by stable interior and real exterior boundary conditions. The main aim of this experimental research is processing of long-term measurements of experimental structures and the subsequent analysis. The next part of the research consists of collecting measurements obtained with assistance of the experimental detached weather station, analysis, evaluation for later setting up of reference data set for the research locality, from the point of view of its comparison to the data sets from Slovak Hydrometeorological Institute (SHMU) and to localities with similar climate conditions. Later on, the data sets could lead to recommendations for design of wooden buildings.

Urban Heat Island: Summer Outdoor Climate Measurement Within the University Campus and City

“…This station is working since 2017. Main reason for obtaining own weather station was to have as accurate outdoor climate for the lightweight wooden walls and windows research as possible and the opportunity to conduct simulations [7,[29][30]. Weather station was developed as prototype by the company Kvant and uses Sensirion SHT21 sensor for temperature/relative humidity measurement.…”

Behaviour of various experimental wall fragments exposed to real climate conditions – temperature measurement

“…Lightweight wall constructions become recently more popular in a way of possible reduction of energy consumption [11]. Both experimental walls consist of 5 vertical sections, detailed description is in [7]. Wood If it is needed to have a good thermal inertia, the material has to have the low value of thermal diffusivity (Fig.…”

“…They were recorded by an experimental weather station. Experimental data correspond to samples at a laboratory scale [7]. Some suitable days were selected for evaluation.…”

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

“…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].…”
