COMIS
Air flow distribution model for multizone structures; takes wind, stack and HVAC into account; allows for crack flow, flow through large openings, and single-sided ventilation. Includes pollution transport model. The structure of COMIS (Conjunction of Multizone Infiltration Specialists) was developed at an LBNL workshop in 1987-88.

Expertise Required
Low-level computer skills required to install program; basic HVAC knowledge necessary.
Users
More than 100 in 15 countries.
Audience
Architects, HVAC engineers, physicists.
Input
Air-flow network, operating schedule, weather data; interactive input program (IISiBat) available.
Output
Preformatted hourly data; user designs reports; graphical output available.
Computer Platform
PC-compatible; source code available for implementation on UNIX-computer; IISiBat graphical interface available for Windows 95.
