The International Code Council (ICC) will be considering the adoption of two ANSI/RESNET/ICC Standards in the 2018 International Energy Conservation Code (IECC). The first is using the ANSI/RESNET/ICC Standard 301 to define how the Energy Rating Index compliance option is calculated. The second will be adoption of the ANSI/RESNET/ICC Standard 380 to define how air and duct leakage testing will be undertaken. To provide information on the two standards RESNET has published two factsheets. The first factsheet is “ANSI/RESNET/ICC 301- 2014: Standard for the Calculation and Labeling of the Energy Performance of Low-Rise Residential Buildings using an Energy Rating Index”. The factsheet introduces standard 301 and covers the following topics: WHAT IS ANSI/RESNET/ICC 301-2014? WHAT DOES ANSI/RESNET/ICC 301-2014 INCLUDE? REFERENCE AND RATED HOME SPECIFICATIONS CERTIFICATION AND LABELING STANDARDS STANDARD 301 AND THE IECC To download the publication go to ANSI/RESNET/ICC 301- 2014: Standard for the Calculation and Labeling of the Energy Performance of Low-Rise Residential Buildings using an Energy Rating Index The second factsheet is “ANSI/RESNET/ICC 380 – 2016: Standard for Testing Airtightness of Building Enclosures, Airtightness of Heating and Cooling Air Distribution Systems, and Airflow of Mechanical Ventilation Systems”. The publication introduces Standard 380 and covers the following topics: WHY ANSI/RESNET/ICC 380 – 2016? IECC Duct Leakage Requirements and Standard 380 IECC Building Envelope Requirements and Standard 380 WHAT IS ANSI/RESNET/ICC 380 – 2016? BUILDING ENVELOPE TESTING Procedures for Measuring Airtightness of Building Enclosures DUCT LEAKAGE TESTING Procedures for Measuring Airtightness of Duct Systems MECHANICAL VENTILATION TESTING Procedures for Measuring Airflow of Mechanical Ventilation Systems To download the publication go to ANSI/RESNET/ICC 380 – 2016: Standard for Testing Airtightness of Building Enclosures, Airtightness of Heating and Cooling Air Distribution Systems, and Airflow of Mechanical Ventilation Systems The publications will prove to be a resource for code officials and other stake holders as they consider the adoption of the 2018 IECC.
