Abstract: One variation of a method includes: accessing a timeseries of aerosol particle concentrations captured via a set of sensors arranged within an indoor environment during execution of an air test and following dispensation of a tracer load; based on the timeseries of aerosol particle concentrations, 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; in response to the outdoor air-delivery rate exceeding a target outdoor air-delivery rate, interpreting a pass outcome for the air test and calculating a set of environmental controls for implementation at an 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.

Abstract: One variation of a method includes, during a test period: triggering release of a tracer test load into air in an environment, according to a set of release parameters, by a dispenser arranged within the environment, the first tracer test load comprising a first concentration of tracers of a first type in solution; and triggering an air sampler, located in the environment, to record a timeseries of aerosol data representing amounts of aerosol particles detected at the air sampler during the test period. The method further includes: deriving a tracer signal, representing changes in amounts of tracers in air detected at the air sampler during the test period, based on the timeseries of aerosol data and the set of release parameters; based on characteristics of the tracer signal, characterizing a set of aerosol flow metrics representing behavior of aerosols in the environment during the test period.
