Development Efforts for COMIS

The Airflow and Pollutant Transport Group maintains several research and development efforts aimed at improving COMIS. This area includes:

• Computational Fluid Dynamics. Many of the limitations of multizone models relate to the lack of detail about the airflow and pollutant distribution in the zones. By contrast, Computational Fluid Dynamics (CFD) models solve the governing equations, and so predict what happens in individual rooms. We use CFD both to quantify the errors that arise in multizone models, and as part of an integrated tool that uses CFD to find details for individual rooms in a whole-building multizone simulation.
   
• Integrated Tools. We extend COMIS by combining it with other programs. In addition to the CFD capability described above, these integrated simulation tools include making whole-building airflow predictions available to other programs, for example outdoor dispersion models.
   
• COMIS development. We develop the COMIS code base as needed to support our research interests.
   
• User tools. We develop tools to make COMIS easier to use. These include a graphical interface, GUICI, and alternate input and output formats.
