Method for characterizing clean air delivery to an indoor environment via an environmental control system

A method comprising:

• during execution of a first air test in an indoor environment within a first test period:
• triggering release of a first tracer load into air in the indoor environment by a dispenser transiently arranged within the indoor environment, the first tracer load comprising a test concentration of aerosol tracer particles;
• and
• recording a first timeseries of aerosol data via a set of sensors transiently arranged within the indoor environment, the first timeseries of aerosol data representing concentrations of aerosol particles present in air at set of sensors during the first test period;
• based on the first timeseries of aerosol data and the test concentration, deriving a first decay rate of aerosol tracer particles detected in the indoor environment during the first test period;
• deriving a clean air-delivery rate for the indoor environment based on the first decay rate;
• accessing a set of building data defined for the indoor environment and comprising:
• a volume of the indoor environment;
• and
• a target occupancy level of the indoor environment;
• based on the clean air-delivery rate and the volume of the indoor environment, estimating a first occupancy level supported by the indoor environment;
• and
• in response to the first occupancy level falling below the target occupancy level:
• interpreting a fail outcome for the first air test;
• generating an electronic notification indicating the fail outcome and the first occupancy level supported by the indoor environment;
• and
• transmitting the electronic notification to a user affiliated with the indoor environment via a native application executing on a device accessed by the user.

A method comprising:

• accessing a timeseries of aerosol data captured via a set of sensors arranged within an indoor environment during execution of an air test, the timeseries of aerosol data representing concentrations of aerosol particles present in air in the indoor environment following dispensation of a tracer load, comprising aerosol tracer particles, into the indoor environment;
• based on the timeseries of aerosol data, deriving a clean air-delivery rate for the indoor environment;
• accessing a set of building data defined for the indoor environment;
• estimating an outdoor air-delivery rate for the indoor environment based on the clean air-delivery rate and the set of building data;
• accessing a target outdoor air-delivery rate defined for the indoor environment;
• and
• in response to the outdoor air-delivery rate exceeding the target outdoor air-delivery rate:
• interpreting a pass outcome for the first air test executed in the indoor environment during the first test period;
• characterizing a difference between the outdoor air-delivery rate and the target outdoor air-delivery rate;
• and
• based on the difference and the set of building data, calculating a set of environmental controls for implementation at the environmental control system within the indoor environment, the set of environmental controls predicted to drive the outdoor air-delivery rate toward the target outdoor air-delivery rate by reducing the outdoor air-delivery rate.
