A ventilation airflow calculator that allows easy, accurate compliance with ASHRAE Standard 62-89. The program automates the cumbersome calculations presented by the Standard's Equation 6-1. The Windows-based program helps building designers design multiple-space ventilation systems that meet the requirements of the Standard. This tool analyzes space and system information from the VAV terminal and air handler unit schedules, calculates ventilation airflow requirements (space minimums and system-level required minimum), and provides additional or revised information for the VAV and AHU schedules.
