Professional Quality Management for the Energy Rating Industry
A national Home Certification Organization built to deliver consistency, transparency, and defensible outcomes—by design.
Recognized by the U.S. Environmental Protection Agency and U.S. Department of Energy.
Why BSI Exists
For decades, the home energy rating industry operated within structures that allowed inconsistency, interpretation drift, and downstream risk to be absorbed by professionals in the field.
BSI was created to address this as a system design problem—not a people problem.
When identical inputs can produce different outcomes, professionalism alone cannot compensate. The structure itself must change.
Common structural challenges included:
• Multiple calculation engines interpreting the same standard
• Quality assurance processes forced to reconcile variance rather than prevent it
• Accountability placed downstream instead of embedded upstream
BSI exists to remove these conditions at the system level.
A Different Oversight Model
BSI is not an improvement layer on existing systems.
It is a different foundation.
The system was designed around governance decisions that prioritize reliability, auditability, and professional integrity.
Structural Consistency
All rating activity operates on a single nationally maintained calculation engine:
OS-ERI, developed and maintained by the National Laboratory of the Rockies.
Transparency & Auditability
Results are traceable to known methodologies, documented assumptions, and reproducible outputs.
Quality assurance verifies conformance—it does not negotiate interpretation.
Standards-Based Governance
The quality management framework aligns with recognized national and international standards, including ISO, ANSI, DOE, and EPA oversight expectations.
Professional Support
Oversight is designed to reinforce competence, accountability, and clarity—without relying on fear, opacity, or discretionary enforcement.
Built in Alignment with Recognized Institutions
BSI operates in alignment with organizations whose mandate is professional rigor and public trust, including:
• U.S. Environmental Protection Agency
• U.S. Department of Energy
• National Laboratory of the Rockies
• American Society for Quality (ASQ)
• Air Conditioning Contractors of America (ACCA)
• Home Innovation Research Labs (HIRL)
• Green Building Certification Institute (GBCI)
These relationships exist to strengthen oversight—not replace it.
Who This System Is Designed For
Designed for professionals who:
• Value consistency over convenience
• Require outcomes that are defensible across jurisdictions
• Prefer standards-based accountability to discretionary interpretation
• Want oversight that scales with professionalism
Not designed for organizations seeking:
• Interpretive flexibility or exception-driven outcomes
• Score optimization disconnected from standards
• Opaque decision-making or informal QA practices
Selectivity Is a Feature
Because system credibility depends on consistent application, BSI is intentionally selective.
Not every applicant is accepted.
Not every organization is a fit.
This protects the integrity of the system—and the credibility of every professional operating within it.
