Hello everyone! I expect to use EnergyPlus to study natural ventilation in buildings. In my research, the air temperature of outdoor air (To) and the solar-air temperature (Tsol-air) are a harmonic function of time with angular frequency ꞷ (To=To+ΔTosin(ωt+φ), Tsol-air=Tsol-air+ΔTsol-airsin(ωt+φ)). So I have to develop an EPW file. At present, I know that Elements can modify the outdoor air temperature (To), but I have no idea whether and how the solar-air temperature (Tsol-air) could be modified in Elements. Does anyone know how to do it, or are there any other ways to achieve my purpose? Thank you in advance for answering my question! I am looking forward to your reply!
