Rescheck
Rescheck was created by the U.S. Department of Energy (DOE) to see that new structures adhere to energy efficiency demands. It can also be used to demonstrate compliance with local, state or federal energy codes for new homes, alterations or additions.
Each building assembly is assessed by Rescheck performing a U-factor x Area (UA) calculation. This calculation establishes the total heat loss (UA) in a house. If the total heat loss through the envelope of the building does not exceed the total heat loss from same building conforming to the code, then the software generates a report that declares the building is compliant with the code.
A Rescheck uses this calculated trade offs. It takes all parts of a home and puts them into an easy-to-read report with a pass or fail grade.
What is a REScheck report?
A REScheck report is a residential energy code compliance document that shows a home meets International Energy Conservation Code (IECC) insulation and envelope requirements. Building departments commonly require it for permits involving new construction, additions, window replacements, or insulation upgrades.
​
Why did my building department ask for a REScheck?
Many jurisdictions require a REScheck to verify that insulation levels, window performance, and building envelope components meet minimum energy efficiency standards before issuing a permit.
​
Does every state accept REScheck reports?
Most states following the IECC accept REScheck reports. Some areas use enhanced energy codes (often called Stretch Codes) that instead require a projected HERS score or ERI score, which can be completed through energy modeling.
​
Can a REScheck report fail?
Yes. If insulation values, window specifications, or other envelope components do not meet code requirements, the report will show non-compliance and revisions may be needed before approval.

What is a COMcheck report?
A COMcheck report verifies energy code compliance for commercial buildings and certain multifamily structures. It evaluates insulation assemblies, lighting power density, and mechanical system efficiency for permit approval.
What is the difference between REScheck and COMcheck?
REScheck applies to residential buildings such as homes and additions, while COMcheck applies to commercial buildings, tenant improvements, and larger multifamily projects.
Manual J Calculation
The Air Conditioning Contractors of America (ACCA) developed the Manual J8 Residential Load Calculation, also known as Manual J Calculation for short, which is a tool outlining the specific requirements for generating residential load calculations for single family residences. This is then used to determine the proper size of heating and cooling equipment that goes into a house.
HVAC equipment required to condition interior spaces without wasting energy is determined by window measurements, insulation, roof design, local climate, and many other factors.
When is a Manual J load calculation required?
A Manual J load calculation is often required before installing or replacing HVAC equipment to ensure the system is properly sized according to ACCA standards and local building code requirements.
​
What happens if HVAC equipment is oversized?
Oversized systems can short cycle, create uneven indoor temperatures, increase energy costs, and reduce equipment lifespan.
What information is needed to complete a REScheck or Manual J report?
Most projects require:
-
Project location
-
Floor plans and square footage
-
Insulation specifications - if available
-
Window and door details, including size and location - a must
-
Construction type (New Construction, Addition or Alteration)
-
HVAC equipment details (for Manual J)
Providing complete information helps speed up turnaround time.
​
How fast can I receive my energy compliance report?
Most residential REScheck and Manual J reports can be completed within hours once required project details are submitted. Commercial COMcheck reports are typically completed within 1–3 business days depending on project complexity.
​
Are your energy reports accepted by building departments?
Yes. Reports are prepared using recognized compliance software and are suitable for submission to permitting jurisdictions across the United States.
​
Do homeowners order these reports, or only contractors?
Both. Homeowners often order reports after a building department request, while builders and contractors use them to prevent permit delays during project planning.
