A TRNSYS Component to Calculate Natural Ventilation and Indoor Air Quality in Multizone Buildings

The prediction of air infiltration is very important when simulating a building, due to the couplingaspects of the thermal and ventilation problem. So, the development of codes capable of performingsimple yet precise calculations is of great usefulness. Their utility can even be enlarged if we addsubroutines capable of air quality calculation and automation of some preliminary but necessaryassessments, like local pressure coefficients over the building facades and wind speed profiles.
