This webinar focuses on two significant proposed code changes aimed at builders, renovators and energy advisors who use (or consider using) energy modeling and airtightness testing to design and build their energy efficient homes. Alex Ferguson from NRCan will explain how the proposed compliance metric for whole building energy use works and which building shapes and architectural features may profit from the new metric. Mark Rosen from Building Knowledge Canada will explain how and why NLR50 is proposed to become the new airtightness metric for code compliance with the NBC Section 9.36. Like Alex, Mark will also highlight which building types may profit from this proposed change. And if time allows after some questions and answers, we will explain how you can access these and other proposed change document and how to submit comments.
