One of our builders cannot find an Energy Star rated bath exhaust fan that also has a one-hour fire rating (the fire rating is for the entire unit assembly of fan/housing/duct attachment). This is multifamily of course, where one-hour and two-hour fire separations between units and floors are a major code issue.\n\nUpdate: You can buy a fan that has a fire-rated damper built in, but none of the usual suspects (Panasonic, Broan, NuTone) make one that is Energy Star. You can still install an Energy Star fan but have to separately design/engineer/build fire-rated dampers inside the exhaust ducts. I\'m working with the builder and his HVAC/Plumbing team to figure out what the additional cost of this would have been. \n
