2016 Low -Rise Residential Mandatory Measures Summary
NOTE: Low-rise residential buildings subject to the Energy Standards must comply with all applicable mandatory measures, regardless of the compliance approach
used. Review the respective section for more information. 'Exceptions may apply.
Building Envelope Measures:
Air Leakage. Manufactured fenestration, exterior doors, and exterior pet doors must limit air leakage to 0.3 cfmlft' or less when tested per
§ 110.6(a)1:
NFRC-400 or ASTM E283 or AAMAIWDMAICSA 101/I.S.2/A440-2011,'
§ 110.6(a)5:
Labeling. Fenestration products must have a label meeting the requirements of § 10-111(a),
Field fabricated exterior doors and fenestration products must use U-Factors and solar heat gain coefficient (SHGC) values from TABLES
§ 110.6(b):
110.6-A and 110.6-B for compliance and must be caulked and/or weatherstri
Air Leakage. Alljoints, penetrations, and other openings in the building envelope that are potential sources of air leakage must be caulked,
