Core and Shell project including restaurant

If the restaurant has the chance for non-smokers to be inside then it is not a designated smoking space. 8/14/2003 ID# 610 The prerequisite requires, "Zero exposure of nonsmokers to ETS by prohibition of smoking in the building, OR, provide a designated smoking room designed to effectively contain, capture and remove ETS from the building". The CIR narrative implies that the entire restaurant is being treated as a smoking room. While this approach will prevent building occupants in other spaces within the building from tobacco smoke exposure, it does not protect non-smoking restaurant patrons from smoke within the space. If smoking cannot be prohibited in the restaurant, the project team and owner may wish to consider creating a fully contained smoking section within the facility that meets the requirements set forth under the prerequisite. Applicable Internationally.

Is the staff serving that side of the restaurant also all smokers? It will be a difficult case to prove. There is a more recent interpretation about connecting a new building to an existing building with smoking. I've modified the text below to your situation. You may want to submit your own official question to GBCI for a ruling. Measures must be taken to ensure that Environmental Tobacco Smoke from the smoking space does not enter the new building. There must be self-closing doors and impermeable deck-to-deck partitions separating the building from the smoking space. Furthermore, there must be an exhaust system sufficient to create a negative pressure differential between the building and the smoking space (or connecting corridor) of at least an average of 5 Pascals (Pa) and a minimum of 1 Pa when the doors between the building and the smoking space are closed. Performance of the required air pressure differentials must be verified by conducting 15 minutes of measurement with a minimum of one measurement every 10 seconds. Note that we are essentially requiring isolation of the connected smoking space with mechanical exhaust as if it were a designated smoking room with respect to the LEED-certifying building. Please refer to Option 2, Case 1, of IEQp2 for additional details on how to properly isolate, and verify the performance of, a designated smoking room. Smoking must also be prohibited within the smoking space within 25ft of the connection to the rest of the LEED building. All other requirements of IEQp2 must also be met for the new building pursuing LEED Certification.
