3202.2.5 Exterior wall covering systems for prior code buildings.
BC § 3202.2.5
For prior code buildings, exterior insulation and associated cladding systems (i.e. rain screens, EIFS, etc.) that comply with Chapter 14 may be applied to the entire facade of a building and may project not more than 8 inches (203 mm) beyond the street line, in accordance with the following: 1. The exterior wall covering system is necessary to comply with the New York City Energy Conservation Code; or 2. In prior code buildings, the installation of the insulation will reduce greenhouse gas emissions, as demonstrated by achieving not less than a thirty percent reduction of the existing thermal envelope UA (the area-weighted average of assembly u-factors, as defined in the New York City Energy Conservation Code) as compared to the improved thermal envelope UA. For the purposes of calculating the reduction in the thermal envelope UA, the improved thermal envelope UA is the area-weighted average of the proposed opaque U-factor times the alteration area of the opaque wall assembly compared to the area-weighted average UA of the existing wall assembly. The UA calculation shall be performed using a method consistent with the New York City Energy Conservation Code. Exceptions: 1. A veneer may be applied to the entire facade of a building erected before December 6, 1968, provided such veneer does not project more than 4 inches (102 mm) beyond the street line.
2.Exterior wall covering systems installed in accordance with this section on prior code buildings may project not more than 10 inches (254 mm) beyond the street, provided they are located more than 10 feet (3048 mm) above grade.
3.The department may approve the installation of exterior wall covering systems in accordance with this section that project more than 8 inches (203 mm) but not more than 12 inches (305 mm) beyond the street line provided they are substantiated with engineering calculations demonstrating need and practical difficulty, and provided that the applicant demonstrates to the Department of Transportation's satisfaction that the projection of the wall covering system will not adversely impact the use of the public right of way.
