Hello! I'm trying to analyze the thermal impact of an open space with a roof of textile material. If is analysed it with a shadow surface until now i found that is impossible to know the space temperature, as well as assigning thermal material properties. Otherwise, if i create an space (and thermal zone) with air walls, i don't know how define different transmittance to the roof surface. Anyone can help me, how could be the best way to analyse the thermal impact of a terrace with textile roof? I'm working with EnergyPlus and OpenStudio. Please...
