Under this prerequisite, school projects must prohibit all smoking inside buildings. Designated interior smoking areas are not allowed. You may designate exterior smoking areas as long as they are 25 feet or more from entrances, operable windows, and ventilation system intakes.

You aren’t required to prohibit smoking during construction, but is good practice and will contribute to compliance with other indoor environmental quality credits, including IEQc3.1 and IEQc3.2, Construction IAQ Management Plan.
