Modular Home QA & Plant Certification

Certified Energy Raters, LLC is one of the few rating organizations in the country that offers a specialized 3rd party Quality Assurance and high-performance-building program for modular home plants.  Offering a high-performance 3rd party quality assured ready product is becoming more and more important for modular home builders to retain maximum credibility in the marketplace. 

Modular plants have a potentially huge advantage over site "stick-built" builders if they so choose when it comes to high-performance and green builds.  This advantage stems from:  

» A stabilized workforce  

» A climate control build environment  

» Standardized Build Practices

» Better Materials Control & Conservation  

Unfortunately, many modular home plants fail to avail themselves of this product and market advantage.  A simple implementation of high-performance build practices as a "standard" feature of the plant design-build and the placement of an independent 3rd Party Quality Assurance verifier to ensure that these build standards are being consistently implemented would result in a much higher quality home than could be duplicated by "site" builders, better customer satisfaction & a broader marketing platform resulting in more sales.
