Systems and methods for indoor air quality based on dynamic people modeling to simulate or monitor airflow impact on pathogen spread in an indoor space and to model an indoor space with pathogen killing technology, and systems and methods to control administration of a pathogen killing technology

A method of modeling and simulating indoor air quality (IAQ) for a heating, ventilation, air conditioning, and refrigeration (HVACR) system, comprising:

• determining behavior parameters for one or more individuals in an indoor space;
• determining spatial parameters of one or more objects in the indoor space;
• generating a model based on the behavior parameters and the spatial parameters;
• and
• determining a critical location of an airflow to disinfect the airflow for the indoor space.

An indoor air quality (IAQ) modelling and simulating system for a heating, ventilation, air conditioning, and refrigeration (HVACR) system, comprising:

• a controller,
• wherein the controller is configured to:
• determine behavior parameters for one or more individuals in an indoor space;
• determine spatial parameters of one or more objects in the indoor space;
• generate a model based on the behavior parameters and the spatial parameters;
• and
• determine a critical location of an airflow to disinfect the airflow for the indoor space.
