Comparison of measurements and simulations of a “passive house”

This paper presents the results of a comparison between measurements of a co-heating test in a passive house and the simulated response of the building to the same outdoor conditions calculated with the building simulation program Trnsys. Special attention is paid to the level of modelling necessary to get an acceptable level of corresponddence with the measurement results. Several improvements are put to the test in order to quantify their impact. Finally, some guidelines for simulating passive houses are formulated.
