Energy Modeling has created a clear barrier-to-entry for passive building professionals that may have been insurmountable for many projects in the past. This has prevented the net zero carbon movement from scaling up in the single family residential market, despite widespread interest. The Phius prescriptive path, introduced under the Phius 2021 certification protocol, offers an alternative path to certification which eliminates the barrier-to-entry posed by energy modeling. This presentation reviews the goals and intent of the Phius 2021 prescriptive path as well as step-by-step guidance through the certification checklist. Webinar hosted by EEBA.
