What RunBrook helps custom home teams accomplish

RunBrook supports custom home teams that need design, energy modeling, testing, and certification services aligned with code requirements, and project-specific performance goals.

  • Meet energy code and certification requirements without compromising design intent

  • Avoid late-stage design changes caused by overlooked performance requirements

  • Coordinate HVAC, envelope, and testing requirements early in the process

  • Pass inspections and verification testing without unnecessary delays

  • Deliver documentation needed for compliance, certification, and closeout

  • Support high-performance homes with project-specific analysis and recommendations

Support for complex envelopes and custom assemblies

Clear documentation for code officials, certifiers, and project teams

How we work with custom home teams

We review plans early to identify performance requirements, code or above-code certification considerations, and coordination needs before they become field issues.

01 Early design review

We prepare energy modeling and performance-related documentation, while coordinating with the project team on HVAC, envelope, and certification requirements.

02 Modeling & design coordination

We perform required field testing and verification services during construction and prior to closeout.

03 Testing & verification

We provide the documentation needed for compliance, certifications, and final project completion.

Incentive or program-driven projects

Common challenges we help solve

  • Unique home designs that do not fit standard compliance assumptions

  • High-performance goals that require early coordination

  • HVAC systems that need to align with custom layouts and envelope conditions

  • Certification requirements that add documentation complexity

  • Late-stage testing failures that create project delays

If your project requires energy modeling, certification support, HERS ratings, blower door testing, or other building performance services, RunBrook can help keep the process moving from design through final verification.
