Buildings.Examples.VAVReheat.Validation.BaseClasses.Floor
Extends Buildings.Examples.VAVReheat.BaseClasses.Floor with CO2 generation from people and CO2 from outside air.
Information
This model is used in the model Buildings.Examples.VAVReheat.Validation.TraceSubstance. It extends Buildings.Examples.VAVReheat.BaseClasses.Floor with CO2 generation from people and CO2 from outside air infiltration. Calculation of the generation from people uses the gain schedule for latent load and assumes 80 W per person latent load to calculate the number of people. Then, it assumes CO2 generation is 0.0048 l/s per person (Table 5, Persily and De Jonge 2017) and density of CO2 to be 1.8 kg/m3, making CO2 generation equal to 8.64e-6 kg/s per person. Outside air CO2 concentration is assumed 400 ppm.
