Emissions

The Emissions object estimates pollutant emissions (CO2, SO2, NOx) produced to meet the electrical demand measured at a parent meter. It must be attached to a meter, from which it periodically samples measured_power and accumulates energy over a configurable cycle_interval (default 15 minutes). At the end of each interval, it dispatches the accumulated energy demand across nine generation sources (nuclear, hydro, solar thermal, biomass, wind, coal, natural gas, geothermal, petroleum) in a user-specified merit order, where each source supplies up to its Max_Out capacity until demand is met, with any leftover demand assigned to coal as a fallback. For each source used, it multiplies the energy produced by that source's conversion efficiency (Btu/kWh) and emission factors (lb/Btu) to compute per-source and total emissions, which are then published as object properties for reporting.

Properties

emissions does not declare inherited parent classes.

The I/O column indicates whether a property is user-settable input (I), simulation-computed output (O), or both (IO).
