Reliable Certification. Fewer Surprises. Predictable Outcomes.
A certification system designed to keep projects moving—without rework, confusion, or last-minute delays.
What Builders Care About (and What We Built Around)
Most builders don’t want to think about rating systems.
They want:
• Inspections to clear on time
• Scores they can plan around
• Documentation that holds up to review
• Fewer callbacks and explanations
• Certifications that don’t become a bottleneck
BSI exists to make certification boring in the best possible way—predictable, consistent, and defensible.
The Problem This System Solves
Across the industry, builders have dealt with:
• The same home producing different ERI scores
• Missed deadlines caused by documentation issues
• Conflicting interpretations during review
• Extra site visits to resolve preventable issues
• Delays that show up late—when schedules are tightest
These problems aren’t caused by builders.
They’re the result of system inconsistency.
BSI was built to remove that inconsistency upstream—before it reaches your project.
How the BSI System Is Different
Consistent Scoring by Design
All ERI scores are generated using OS-ERI, the nationally maintained calculation engine developed by the U.S. Department of Energy and managed by the National Laboratory of the Rockies.
That means:
• Identical homes produce identical results
• Scores don’t shift based on software or interpretation
• Targets are easier to plan around
One Verified Software Path
Ratings are completed using a single, validated platform—HouseRater—aligned directly to the national calculation engine.
No parallel tools.
No conflicting outputs.
No guessing which number will “stick.”
Documentation Checked Early
Inputs and documentation are reviewed before certification, reducing:
• Late-stage corrections
• Surprise QA issues
• Reinspections that disrupt schedules
What This Means for Your Projects
Builders working within the BSI system experience:
• More predictable certification timelines
• Fewer last-minute issues
• Less back-and-forth during review
• Clearer expectations from day one
• Certifications that clear without drama
The goal is not tighter control.
The goal is fewer interruptions.
This Is Not a New Program to Learn
BSI does not change:
• Your codes
• Your performance targets
• Your certification programs
ENERGY STAR®, ERI, Efficient New Homes, and code compliance requirements remain the same.
What changes is the system enforcing them.
Why Selectivity Matters (and Why It Helps Builders)
BSI is selective about who operates within its system.
That selectivity ensures:
• Consistent application of standards
• Predictable review outcomes
• Reduced risk of corner-cutting elsewhere affecting your project
Builders benefit when everyone in the system is held to the same expectations—quietly and consistently.
What Switching Does Not Do
Switching to a BSI-supported rater:
• Does not invalidate past certifications
• Does not require public explanations
• Does not change your builder relationships
• Does not create disruption
Transitions are handled procedurally and without noise.
Who This System Is Best For
A strong fit if you value:
• Schedule reliability
• Defensible documentation
• Fewer surprises during inspection and review
• Professional, standards-based oversight
Not a fit if you rely on:
• Flexible interpretation to hit targets
• Last-minute adjustments
• Variability as a planning strategy
The Bottom Line
Certification should support construction—not compete with it.
BSI was built so that:
• Scores are consistent
• Reviews are predictable
• Projects move forward without unnecessary friction
If your goal is fewer interruptions and more certainty, this system was designed with that reality in mind.
