Stretch Code for HERS Raters

Timing: Tuesday, June 25th @ 1:00 p.m. – 4:00 p.m. EDT.

Location: Online - Webinar

The Massachusetts Stretch Energy Code incorporates a blend of energy rating requirements and International Energy Conservation Code (IECC) requirements, which often leads to confusion. This course covers the requirements of the Energy Rating Index (ERI) path, as amended by Massachusetts, and IECC “mandatory” requirements. This course, specifically designed for HERS Raters, reviews details of the ERI path, including rating standard options, renewable energy bonuses, and verification and documentation requirements. It will also discuss every IECC requirement that is mandatory under the ERI path, including envelope, mechanical system, service hot water, and whole-house mechanical ventilation. The course will also describe duct leakage testing requirements, including IECC and RESNET 301 testing exemptions and related modeling issues. Finally, the course will briefly touch on the alternative ERI path (Passive House), EV-Ready requirements, and solar-ready requirements.
