Abstract:

Input files for the multi-zone airflow and contaminant dispersal computer program CONTAM88 are described for four large buildings. The files were developed for a twelve-story multi-family residential building, a five-story mechanically-ventilated office building with an atrium, a seven-story mechanically-ventilated office building with an underground parking garage, and a one-story school building. The physical characteristics of each building and its idealization as a multi-zone airflow system are described. These input files enable a user to employ CONTAM88 to study airflow and contaminant dispersal in these large buildings without developing building idealizations and inputting them into CONTAM88. Results of selected computer simulations are presented to demonstrate the effects of wind speed, indoor-outdoor temperature difference, and the percentage of outdoor air intake in the supply air on air change rates and interzonal airflows for these four buildings. Appendices are also included that contain a building component leakage database useful in multi-zone airflow modeling and updated information on the use of CONTAM88.
