About Mandatory Provision ASHRAE 90.1-2010 point 5.4.3.2 Air Leakage. Must this prescription be applied also to fenestration and doors of a warehouse not heated or cooled? We are in Climate zone 4. The warehouse area will be occupied and ventilated with Exhaust air (EA by Exhaust fan) and Makeup air (OA by louver provided with filter media and flow monitoring).
Are skylight and smoke-out skylight included in the fenestration category?

Unconditioned spaces do not have to meet the envelop requirements.
