About Refresh Homes


jump to section:



Refresh Homes strives to provide affordable, accessible, useful, and accurate information regarding residential and commercial energy efficiency, safety, comfort, and durability.


Refresh Homes has been in business for over fifteen years. Initially providing renovation and design services, we quickly realized how most buildings and homes were built to be incredibly inefficient. Many were not up to minimal local building code standards, much less up to recommended building science standards.

Prefix Designs

Owner Marshall Minshew graduated from the College of Architecture and Design at Kansas State University with a Bachelor of Science in Interior Architecture then moved to Kansas City and founded Prefix Designs --a space planning and adaptive reuse design firm. Prefix Designs worked with local and regional architects on projects as varied as historical preservation (Topeka Independent Living Resource Center; five-story building in downtown Topeka) to national retail design accounts (Hallmark Cards, Inc.)

Hallmark Cards, Prefix Designs' largest account, eventually hired Marshall full-time where he stayed four years designing for independent retailers nationwide. He designed plans, fixtures, and lighting, as well as developed and implemented new store concepts for corporate prototype stores.

Refresh Homes

After Hallmark, Refresh Homes was established to provide renovation and design services, energy audits and thermal imaging for residential and commercial clients in the Kansas City area.

During 2006 to 2008, Conservation Services Group (CSG) hired Marshall full-time to help implement New Jersey's Home Performance with ENERGY STAR® Program by providing Quality Control and training contractors for BPI certification. Marshall also served as the Lead Solar Inspector for New Jersey's Clean Energy Rebate Program.

BPI Affiliate

From 2008 through 2011, Refresh Homes was a BPI Affiliate, offering individualized training and testing towards BPI certification and accreditation of home performance contractors. We offered residential and commercial thermal imaging services and BPI-recognized Continuing Education.

In 2011, Refresh Homes created the Proctor Network™ in response to rapid growth in demand for BPI Certifications and testing. The Proctor Network™ was designed to help BPI Certified individuals across the country become BPI Proctors and BPI SuperProctors and to enable them to independently proctor BPI certification exams (online tests and field tests) according to their location, schedule, pricing, etc.
