Upon repair or alteration of any window in a residential building which leads to an unheated area, such window shall be weatherstripped so as to effectively and reliably limit air infiltration. Any window which is fire-rated is specifically exempted from this requirement. In determining which types of weatherstripping are acceptable, the Director shall consider, among other matters, whether the weatherstripping meets the energy conservation goals of this Code and is cost-effective.
