NIST Multizone Modeling

The use of multizone modeling in more practical applications is increasing. Along with building research, multizone modeling can be applied to areas of building design and operation.


Contam Concept

This website was developed by the Indoor Air Quality and Ventilation Group to foster the development and facilitate the application of multizone ventilation and indoor environmental modeling in the areas of building design, operation, maintenance, investigation and research. Within this website you download the multizone airflow and contaminant transport modeling software, CONTAM and other modeling tools, information on the applications of the tools, and associated case studies.
