Re: Is it possible to get negative value for conduction gain

Dear CP,

thank you for your reply. really appreciate it :) I understand now about the negative conduction gain and its role in building thermal analysis.

I will further do my research now.

where to get annual cooling/heating load in vista?

I am sorry if this question is so basic, but still I still confuse where to get annual cooling/heating load result in vista

I know if I unselect the building geometry then I can see 'load', 'energy' and 'carbon'.

So I look at the 'load ...

Re: Negative Conduction Gains

hi iwmech,

I also experience the same result with you, my 11th-story building have negative conduction gain. as you said, conduction gains are a result of the building fabric absorbing the heat. I want to compare the conduction gain of the bare flat roof compare with the green roof (in this case I ...

Is it possible to get negative value for conduction gain?

I did some 11-story building model for my thesis and run apachesim , I found the electricity consumption, energy consumption, room cooling load and heating load, but when I try to look at external conduction gain and roof conduction gain, the value is all negative. What does it mean?did I do ...

Green roof modelling in Apache cdb

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 ...
