Energy Code Compliance
Expert Energy Code Compliance Solutions
Building projects must demonstrate compliance with the energy codes adopted by their jurisdiction. Our specialized energy consulting services help design teams navigate both compliance pathways—prescriptive and performance-based—with a focus on achieving optimal results through the performance path approach. From COMcheck documentation for smaller commercial permits to advanced performance path modeling for complex buildings — we handle the full spectrum of energy code compliance under IECC and ASHRAE 90.1, including the 2024 IECC and ASHRAE 90.1-2022.
The Prescriptive Path
For contractors, architects, and engineers needing fast permit-ready compliance documentation, we produce commercial COMcheck reports on a flat-fee basis — no hourly billing, no surprises. Our COMcheck service covers building envelope, lighting, and mechanical compliance certificates accepted by most U.S. building departments.
| Project size | Service | Fee |
|---|---|---|
| Up to 3,000 ft² | Complimentary COMcheck report | Free |
| Up to 10,000 ft² | COMcheck report + plan review checklist | $150 |
| Up to 25,000 ft² | COMcheck report + plan review checklist | $300 |
| Up to 50,000 ft² | COMcheck report + plan review checklist | $500 |
| Up to 100,000 ft² | COMcheck report + plan review checklist | $750 |
| Larger or complex projects | Custom scope | Custom quote |
Additional fees may apply for expedited delivery, extensive revisions, or complex systems.
What's included in your COMcheck report
- Commercial COMcheck documentation
- IECC compliance coordination
- Permit submission support
- Plan review response assistance
- Minor revisions included
- Fast turnaround for standard projects
The Performance Path
For larger commercial projects where prescriptive compliance is impractical or limiting, the performance path uses advanced energy modeling software to demonstrate IECC or ASHRAE 90.1 compliance by calculating annual energy savings compared to the baseline building— rather than evaluating each component in isolation.
This systems-level approach lets design teams make trade-offs: a high-performance envelope may offset a less efficient mechanical system, for example. The result is the same code compliance target with far greater design freedom.
Why choose performance path over prescriptive compliance?
- Design flexibility: Prioritize strategies based on architectural, programmatic, or sustainability goals — not fixed component thresholds.
- Cost-effective allocation: Direct energy investment where it delivers the most value rather than meeting prescriptive requirements across every assembly.
- Future-ready compliance: Flexible modeling adapts more naturally to increasingly stringent IECC and ASHRAE code cycles.
- Operational cost estimates: Delivers realistic building energy cost projections for clients and stakeholders before construction begins.
Holistic Building System Integration
The performance path treats the building as one connected system, not a set of separate components. Design becomes an integrated process where:
- Window quality affects solar heat gain and HVAC sizing requirements
- Envelope and lighting choices change heating and cooling loads, and with them the size and cost of the HVAC system
- Multiple building systems work together toward efficiency goals
For complex buildings and those with innovative efficiency technologies, the performance path usually gives the best result. Prescriptive requirements alone rarely capture how the systems interact.
Performance Path Implementation Benefits
The performance-based approach promotes energy-conscious early design integration by positioning energy considerations among the critical factors determining a building's form and functionality. This energy-focused design methodology delivers multiple advantages:
- Cost-Effective Energy Strategies:
Allows design professionals to prioritize energy-saving measures based on cost-effectiveness rather than prescriptive requirements - Design Innovation:
Frees creativity and innovation from the limitations of prescriptive component requirements - Workflow Efficiency:
Familiarizes design professionals with modeling workflows applicable to beyond-code targets and certification programs
