4.5 Conclusions
In order to develop appropriate control strategies of the main variables which influ-
ence human comfort (temperature, relative humidity and CO
2
concentration) it is
necessary to use models able to capture the dominant dynamics of the modelled
system. In this chapter, different techniques that allow to obtain a room-level cli-
mate model have been presented. More specifically, in a first approach, an analysis
