An existing 36000 sq ft cold storage warehouse on Titletown, Wisconsin is being renovated into a furniture manufacturing facility. The new building will reuse the existing building and will include a 40000 sq ft addition in order to create office spaces and a product showroom. Due to Titletown's extreme winter temperature, the building owners would like to include a designated indoor smoking area for their employees. What are the design criteria for non-residential buildings that include indoor smoking areas, as required by EQ Prerequisite 2, Environmental Tobacco Smoke (ETS) Control (describe it in the context of this warehouse)?
