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.
Keywords
multizone airflow, pollution transport
Validation/Testing
N/A
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.
Programming Language
FORTRAN
Strengths
Detailed analysis with user-defined schedules; takes many flow paths into account;well
documented; has been validated by the International Energy Agency's Energy Conservation in Buildings
and Community Systems Programme, Annex 23 on Multizone Air Flow Modeling. Graphical user
interface, IISiBat, allows for rapid development of input file.
Weaknesses
Nodal model; no CAD-like interface for describing the geometries.
