Adequate ventilation with the "right amount of air, to the right place and at the right time" are important factors for achieving a good indoor climate. Thus it is of prime importance that the ventilation system is working properly. Using traditional methods, it is a very time consuming, and some times even impossible, task to balance ventilation systems to achieve correct air distribution. In most countries the growing concern about Indoor Air Quality has resulted in Building Codes demanding increased ventilation rates.
This is the first part of a planned research into the effect of the human being on the indoor climate. The results are among other things intended for CFD calculations. This part deals with the influence from breathing, smoking, bioeffluents and vapour. The results are mainly based on measurements around a breathing thermal model placed in three fundamentally different types of indoor climates:
