NEWARK — Energize Delaware, New Ecology and Green Building United have joined to host a three-day, in-person Phius Certified Builder training July 19-21.

Each day’s course will run from 8 a.m. to 5 p.m. in Newark. The location will be given upon registration.

The cost is $1,550, which includes materials, test registration, and breakfast and lunch all three days.

Registration is open until July 11, but space is limited. Sign up at energizedelaware.org/passive-buildings.

Phius Certified Builders are taught how passive building techniques — such as airtight envelopes, high-performance window installation, third-party quality assurance and attentive site management — result in highly efficient, healthy and resilient construction.

The upcoming session will focus on high-performance building systems, with an emphasis on field inspection, climate-specific construction detailing, air barriers and passive building retrofitting.

Passing the certification exam earns the trainee the Phius Certified Builder credential, joining over 3,000 others in the U.S.

Phius, a 501(c)(3), has the goals of implementing a zero-carbon environment through building science, supporting construction professionals and designers, and certifying the majority of all passive house projects in North America.

Energize Delaware will reimburse a portion of the tuition for those who earn certifications: 75% of the cost for Delaware residents and 50% of the cost to employees of companies licensed in Delaware.
