Measurement of Lightweight Experimental Wall and Comparison with Different Simulation Programs

Abstract

This article deals with the long-term testing of experimental lightweight wall and comparison of the measurement with two different simulation software packages – WUFI and ESP-r in term of temperatures inside the fragments. Two lightweight timber-frame wall fragments with various outdoor coating colors were exposed to the real outdoor boundary climate conditions for four years. The indoor boundary conditions were secured as constant. In the wall fragments there are several built-in sensors.

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.…”

“…

Outdoor climate is an important part of the set-up of simulation in civil engineering of any kind (heat-air moisture transport, heat and cool demand, overheating, etc.). Not only detailed outdoor boundary conditions [1-3], but also the material properties of used materials [3][4][5][6] and the used simulation tool and appropriate model from vast selection are important [7]. Several works deal with the accuracy of used outdoor climate [1,2,6,7].
