But I don't think you can translate it clearly this way. I haven't yet understood the sentence: is the 模拟试验之数据推导 something that will happen in the building? Or is it a part of the design process? If we're just talking about the design process here, then my best guess is that this sentence means:

"We ran a data simulation on the positively-pressurised corridors."

But I might well be missing something.
