COMcheck is a U.S. Department of Energy tool used for selected commercial energy compliance analyses. A passing COMcheck report must reflect the correct NYC code edition and the actual systems shown on construction drawings.
New York City recognizes distinct COMcheck implementations for the 2025 NYCECC and 2025 NYC ASHRAE 90.1 compliance approaches. The filing professional must select the governing method, address NYC-specific requirements and document design values not fully represented by the software.
A useful starting point is to review the work or facility type, the controlling rules and the documents already available. See all Energy Code topics for a broader comparison of the subject.

The review should start with a practical question: confirm whether the project is eligible for COMcheck and whether it follows NYCECC commercial provisions or NYC ASHRAE 90.1. Relevant records and professional advice may change how the team addresses that question. One common error is using a report for a code edition that is different from the one applicable to the filing. Each decision should be tied to the specific project facts.
Whether this topic calls for a formal filing, field review or further professional advice depends on existing conditions and applicable rules. Keep the records and responsibilities of each regulator separate.
SLK Buildings supports record organization and project coordination; regulated professional work and legal determinations remain with appropriately qualified providers.
Confirm the current code edition, permit classification, available energy analysis and signed drawing set. Check whether new construction, work at an existing building, trade coordination or required inspections change the next step. A report should never be treated as a substitute for current approved plans.
When a design or field condition changes, the responsible professionals should assess whether the energy analysis, supporting documents, progress inspections or sign-off package must be updated. Agency acceptance and professional certifications should be confirmed in the project record.
For help organizing records and professional coordination concerning COMcheck, contact SLK Buildings or request a proposal. Provide the property address, available job or case number, work description and the documents already received. The right service scope depends on project facts and qualified professional review.
