A TRNSYS Simulation and Experimental Comparison of the Thermal Behavior of a Building Located in Desert Climate Available to Purchase

This paper describes a TRNSYS simulation of a space of an office building in dessert climate. The space simulated by TRNSYS represents a meeting room which is placed in one of the high mass buildings of the Plataforma Solar of Almeria located in the desert of Tabernas, Spain. The meeting room was selected because hygrothermal variables are being measured. The simulation results are compared with experimental data of the meeting room. The main goal is to describe the thermal behavior of the meeting room of this high mass building in free evolution and verify its thermal performance with the measured data. Climate input variables to the simulation were solar radiation, dry bulb temperature, relative humidity and wind velocity recorded by a meteorological station installed on top of the building. As a first approach coolest winter day and hottest summer day were analyzed. The comparison results between the TRNSYS simulation results and measured ones show a maximum percentage difference of 4.51% (0.60 °C).
