For each problem area—such as poor indoor air quality in the Safety Pillar or lack of thermal comfort in the Comfort Pillar—Pearl identifies specific high-performance features that can mitigate or eliminate that problem. Points are assigned based on several factors, including whether a feature meets a defined threshold of performance or quality, the specific characteristics of the feature (e.g., efficiency ratings, specific functionalities), and the quality of its installation. Points are awarded for installations documented as adhering to recognized industry protocols or those verified through performance testing.

28 million U.S. residents suffer from asthma caused partly or entirely by poor indoor air1. Over 5 million homes have high radon exposure, resulting in approximately 21,000 deaths a year2.

Blind Spots to Insights: Making Value Visible

Pearl transforms often overlooked home performance features into tangible, measurable value within the real estate marketplace. By capturing detailed data on a home's Safety, Comfort, Operations, Resilience, and Energy (SCORE) attributes—backed by building science and third-party standards—Pearl assigns a comprehensive SCORE™, illuminating features that traditionally go unnoticed. This rigorous evaluation translates into a visible, credible, and easily understandable metric. This SCORE™, and corresponding Pearl Medallion status, empower homeowners to showcase their investments and enable buyers to make informed decisions, effectively converting hidden performance enhancements into market-recognized and appreciated value.
