Abstract: This paper presents the implementation of a low-order model used to evaluate the thermal behavior of a high number of buildings (district level) via simulation. This model is based on a second degree configuration (R6C2 – six resistors and 2 capacitors) and is implemented in Modelica. The model is validated with several cases from the BESTEST building envelope test. In parallel, a direct comparison with a detailed multizone building model using the Buildings Library from Wetter, et al. (2014) was performed. The results show that the low-order model allows to assess the building thermal demand and the indoor temperature with good accuracy.
