Green roof modelling in Apache cdb
Posted: Thu Apr 17, 2014 7:42 am
I try to model educational building with green roof and want to make different in thickness and LAI(leaf area index) to see the different result of heat gain/loss of the building. I found the soil thickness part in 'roof' menu in cdb, but I cannot find where to change LAI.
Can anybody tell me where should I change it? is it even possible to change the LAI in green roof construction in IESVE?
I also read some research paper told that iesve cannot calculate evapotranspiration gain(Qet) and convection gain(Qconv) ,is it true? so I wanna ask, does evapotranspiration and convection have significance effect in cooling or heating load of the building?if so, should I do another calculation after the simulation take place?
I try to look for the answer but still didnt find anything. Please help me T_T
