Churches are unique in that the sanctuary may have very high ceilings and a need for quiet during lengthy prayers.
I suppose there is a good reason why bars are open seven days a week while churches are only “open for business” on Sunday. In many ways they are similar. There is one main character in each, the Minister, Rabbi, or Imams for the church and often a single bartender for the drinking establishments. These leaders all will listen to your problems, provide counseling, and will gladly accept “donations” for their work. Church members sit on committees to make suggestions as to where the church is headed and provide criticism if they feel the need to do so. Some bar “regulars” do the same, especially after imbibing too much of an unholy “spirit”. The church choir offers inspiring hymns, and while larger churches may hire professional singers, the choir is a chance for wanna-be singers to showcase their vocal talents. Bars don’t have choirs, but they do have karaoke night where solo performances are the focus. One more important similarity is that a church and a chapel sized bar need proper HVAC to maintain a comfortable setting for those who attend. Churches are unique in that the sanctuary may have very high ceilings and a need for quiet during lengthy prayers. These are both challenges for any HVAC design. Some bars still allow smoking so the area must have proper ventilation to keep the smoke away from any dining area. The HVAC in both places will need to account for the heat generated from the bodies of those gathered to dance to the jukebox on Saturday night or atone for the previous night’s behavior on Sunday morning. Bars and churches may have similar HVAC needs but I don’t think running a pew along the bar or setting up wooden bar stools in a church is a very good idea.
