2. operator absent fume hoods in the facility then determine how long the occupied hoods are in use during a typical day and select a control approach which enables you to safely downsize mechanical systems Several studies have shown that typical hood usage is about one hour per day LabPro uses data from a study in which actual usage of hundreds of fume hoods were monitored T he results reveal average usage ranges from about one hour per day for a typical research hood to four and five hours for some analytical and process hoods Employing a simulation program which can run thousands of simulations in seconds LabPro can predict the number of fume hoods in the facility that will be occupied at any given time It also predicts average number of fume hoods being used during a typical day By entering the number of fume hoods on a manifold the probability that the users are in front of their hoods example one hour in a ten hour day equals a 10 percent probability and the percent design criteria defined as the design point such that the system requirements are met a given percent of time along with the airflow levels for occupied and unoccupied fume hoods LabPro can determine both design and average airflow requirements for the facility Once LabPro determines the design flow requirements it uses accepted sizing calculations to estimate the size of supply exhaust and central plant equipment After calculating the equipment size LabPro again u
