||One of the main problems about air flows pattern studies remains the
experimental validation of numerical codes developped for interzone air flow and
polluant diffusion prediction.
A few years ago, CETHIL developped a real scale experiment made of a
88mē dwelling built in our laboratory hall in a controlled climatic environment. This
experimental tool allows a full control of outdoor climatic conditions: air
temperature, relative humidity, pressure drop can be controlled on the six faces of
the cell: OPTIBAT is thus a reference tool for multizone air flow measurement
techniques, and experimental data sets available for validation of numerical models.
The first phase of this experimental projet allowed us to determine air leakage
characteristics of indoor and outdoor walls of the cell.
The second element required for the validation of multizone air flow codes is
the knowledge of all the interzone air flows. The vast majority of the air flow
measurements made to date have involved multiple tracer gas techniques. Using the
OPTIBAT facility, we have first used only one tracer gas to determine all the air
The present paper describes the experimental cell and gives the first results
about air flows measurements using tracer gas technique. The interzone air flows
are computed using two methods. Each method is completed by an error analysis
which defines the uncertainty of each result. Both methods give the same results.
