PHIUS Certified Passive House Consultant (CPHC®) Training Program
CPHC Trainees receive a free 8-week license to the WUFI® Passive software. WUFI Passive, which combines passive building energy modeling with dynamic hygrothermal modeling capabilities, is also available for purchase from Fraunhofer IBP.
WUFI Passive requires Windows OS. Mac users need to purchase and install VMWare Fusion, Bootcamp or Parallels, along with a Windows operating system. VMWare Fusion is recommended. See the full WUFI Passive system requirements here.
In addition, students must install LBNL THERM. Always download the most recent NFRC-approved version.
The most recent STABLE version as of November 2014 is 7.3.2. It is available as a free download here.
There are known technical issues with THERM installation on Windows 7 and Windows Vista - special installation information for these operating systems can be found here.
Earn the leading passive building credential in North America – become a PHIUS Certified Passive House Consultant (CPHC®) today!
CPHC is the only professional passive building credential training program that includes instruction in energy modeling software and the only professional passive building credential with a continuing education program.
First launched in 2008, PHIUS established the Certified Passive House Consultant (CPHC®) credential to distinguish accomplished passive house professionals in the marketplace. CPHC training was the first – and is still the only – passive building training program tailored to North America’s unique climate variations, market conditions, and building components. PHIUS, the leading North American passive building training provider, has trained over 2,000 professionals to date, including 1,350 CPHCs.
PHIUS-trained CPHCs are leading the adoption of passive building from coast to coast by designing and building quality-assured PHIUS+ Certified passive building projects across all of North America's varied climate zones. Projects earning PHIUS+ Certification follow RESNET QA/QC protocols and achieve both excellent HERS scores and US Department of Energy Zero Energy Ready Home (formerly DOE Challenge Home) status.
Here's your chance to join a robust community of industry leaders and learn the core principles and skills you'll need to be a successful passive building practitioner.
New CPHC Training Platform Launches Spring 2017!
The new CPHC online training platform offers engaging videos featuring PHIUS trainers.
We are pleased to announce that we are launching an exciting new online platform for the Phase I: Online portion of CPHC training that will make self-guided learning easier, more effective, and engaging. The new platform puts into practice the latest recommended best practice tools and strategies of online learning. PHIUS's new partner in this endeavor is Saturn Resource Management, a pioneer in the world of designing online learning systems. Today, the company is one of the most experienced and seasoned online education experts out there. Even better, they also have deep roots in high-performance home and building science education. Together we are working to deliver the highest quality curriculum and advanced skill set necessary to help you become a successfully practicing passive building professional.
- Phase I is offered as online sessions taken at your own pace. Virtual sessions are taught as pre-recorded webinars led by seasoned PHIUS-trained expert instructors with the latest, continually updated curriculum.
- Phase II is offered as five-days of in-class instruction geared specifically toward modeling software and exercises that require personal interaction. Participants travel only once as part of the Phase II in-class CPHC training, reducing travel and lodging costs and overall fees.
- The CPHC exam (optional) is offered on site on the last afternoon of training. Participants must complete both Phase I and II of the training to be eligible to take the final exam.
