1. A heating, ventilation, or air conditioning (HVAC) system, the HVAC system comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
performing a plurality of simulations for a plurality of different equipment configurations using a temperature model, an infectious quanta model, and an infection probability to provide results;
using the results of the plurality of simulations to provide (i) a user interface that indicates a tradeoff between the infection probability and at least one of energy cost or energy consumption and (ii) at least one of design data comprising one or more recommended design parameters or operational data comprising one or more recommended operational parameters for the HVAC system; and
initiating an automated action using at least one of the design data or the operational data.
