Weatherization Assistance Program

Intermountain Weatherization Training Center
The Intermountain Weatherization Training Center (IWTC), established in 2009, was designed to support the advancement of residential energy efficiency through hands-on, technical training. It also serves as a resource for collaboration among weatherization professionals, energy partners, utilities, educational organizations, and others interested in residential energy efficiency and building science. This 14,000-square-foot, all-weather facility is located within a large warehouse and was built to simulate real-world conditions for weatherization work.
The IWTC is equipped to support hands-on learning and technical demonstrations in a variety of residential energy efficiency practices, including:
- Traditional vs. advanced energy efficient building practices
- Whole house pressure diagnostics and air leakage testing using blower doors, pressure pans, etc.
- Duct sealing and pressure testing using "duct blaster" technology
- Infrared thermography of building components
- XRF identification of existing lead-based paint
- Attic, wall, floor, foundation and duct insulation
- HVAC installation, repair, diagnostics, venting and duct fabrication
- Energy efficient lighting technologies
- Computer based training of all types
Trainings, Tours, & Inquiries
At this time, the training center does not offer courses or facility access to private individuals, contractors, or commercial organizations. Training and technical assistance resources are prioritized for Weatherization Assistance Program (WAP) grantees and partner agencies. As capacity allows, the IWTC may support additional collaboration and training opportunities in the future.
