雖然在商業建筑與多種居住房的被動消防中，防火閥是關鍵組件，但在對建筑和其居住者的安全保護中，很多管理者沒有意識到防火閥的作用以及規定時間間隔內，防火閥的檢測、清潔及維護的重要意義。在值得信賴的電動防火閥商業建筑中的建造中我們總會遇到一些麻煩，試圖在能源效率與室內空氣質量之間尋求平衡就是其中。大多商業建筑通過機械通風或空調系統解決，能夠測量和控制整個建筑的空氣變化。在通風管道系統的安裝上就存在上面提到的問題———如何在延遲或電動防火閥阻止火(huo)災蔓延的(de)(de)建筑防(fang)火(huo)分隔(ge)與(yu)所允許空(kong)氣(qi)(qi)自(zi)由流(liu)(liu)通(tong)(tong)的(de)(de)需要(yao)(yao)之(zhi)間達(da)到(dao)平衡。滿(man)足空(kong)氣(qi)(qi)自(zi)由流(liu)(liu)通(tong)(tong)需要(yao)(yao)不可避免地再引入一條(tiao)通(tong)(tong)道，而這卻加快(kuai)了火(huo)勢的(de)(de)蔓延———利用通(tong)(tong)風管道系統(tong)使用的(de)(de)通(tong)(tong)道。毫(hao)無疑(yi)問，這中斷了防(fang)火(huo)分隔(ge)，充當了建筑被動消防(fang)護面的(de)(de)“裂口”。
