.Buildings.Examples.VAVReheat.Validation.BaseClasses.Floor

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 internal gain schedule and uses 0.05 people per m² along with the zone area 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.
