Answer the following questions using the three-zone indoor air quality model tutorial.
What layout in a real home might be realistically represented by three zones?
Adjust the volumes and air flows for the three zones to represent a layout you have in mind. How much exposure might a person in one of the adjacent rooms to a smoker receive in the layout you have chosen?
Using the two-zone mass balance model interactive tutorial, answer the following questions about particle dynamics in two rooms that are connected by an open or closed doorway.
Under what conditions can concentrations in Room #2 exceed those in Room #1?
What parameters affect the distance in time between the concentration peaks in each room?
How realistic do you think this model in describing air pollutant levels in two separate rooms of a real home due to smoking or some other pollution source? What added features would make it more realistic?
List your group's macroactivities and durations for each macroactivity. Compose tables (e.g., Excel PivotTables) summarizing the microactivities (duration in microenvironments, average duration of contact with each object, and frequency of contact with each object) within each macroactivity. Do this for each member of your group. Describe differences or similarities in microactivity statistics and potential reasons for these attributes.
Based on your analysis of activity patterns, state your opinion (with justification) on utilizing macroactivities for modeling dermal
The purpose of this assignment is to create your own personal activity pattern profile and gain insight on the benefits and limitations of the indirect exposure assessment approach.
