Do you have a new single or multi-family residential construction project that requires duct, envelope, or ventilation testing? What about any green building certification requirements?

Blower Door Test

Partnering with a trusted green building consulting company is an excellent way to hit energy code compliance standards and pursue green building certifications. Our team offers green building subcontracting services from start to finish. We work on both new and existing projects, including residential, multi-family, and commercial installations.

We work with builders, contractors, other green building consultants, building managers, architects, property managers, and MEP engineers to offer high-quality testing and verification services. If your company is having trouble covering fieldwork, or cannot comply with the new energy code measures, you can subcontract work to Northwest Energy Collaborative to keep projects on schedule. Our office is in Portland, Oregon, and we work within a 4-hour driving radius.

Our dedication to accuracy, the continued training and development of our staff, and a clear scope of work make Northwest Energy Collaborative an excellent choice. Our principals, William Castrillón and Jonathan Wrobel are hands-on with every project. They ensure accurate results and manage the testing crews from the field, not from a cushy corner office.
