The adjacent walls effects in simplified thermal model of buildings

Share this Post:

The thermal network method is a reliable approach to study the thermal performance of buildings. It is able to simulate the indoor temperature, heating and cooling loads by means of a set of ordinary differential equations. In this work, a 4R3C thermal network has been proposed to study a detached building.

 

Combinations of thermal networks are addressed in order to consider the effects of adjacent walls in other typologies (semi-attached and terraced). Corresponding models, generated by the TRNSYS software, provide the training data used to identify the parameters in the thermal networks. At the end, the accuracy of the model’s output and identified parameters is discussed.
