REScheck is a software program developed by the U.S. Department of Energy (DOE) to help ensure that new residential and commercial buildings meet the energy efficiency requirements of the International Energy Conservation Code (IECC). The program is used by architects, engineers, builders, and code officials to calculate the energy efficiency of a building and ensure that it meets the minimum requirements for insulation, windows, and other features.

REScheck uses a series of input fields to calculate the amount of energy a building will use, based on factors such as its location, size, and building materials. The program then generates a report that shows whether the building meets the energy code requirements and, if not, which parts of the building need to be improved to comply.

REScheck is an important tool in ensuring that buildings are designed and constructed with energy efficiency in mind, which can help reduce energy consumption and lower utility costs for building occupants.

REScheck is used by architects, engineers, builders, and code officials to determine if a new building or renovation project meets the energy efficiency requirements of the International Energy Conservation Code (IECC). Here are the general steps to use REScheck:

•  Enter the building location, climate zone, and project details: This includes information about the building's insulation, windows, doors, walls, floors, and roof, as well as the HVAC system and lighting.
•  Verify compliance: Once the input data is entered, the REScheck software will calculate the energy consumption of the building and compare it to the requirements of the IECC for that location and climate zone. If the building meets the energy efficiency requirements, then it is compliant. If it does not meet the requirements, then adjustments can be made to the building design to improve its energy efficiency.
•  Submit the report: Once the compliance report is generated, it is typically submitted to the relevant code enforcement agency as part of the building permit process.

REScheck can be a useful tool to ensure that buildings are constructed to meet energy efficiency standards, which can help reduce energy costs and minimize the building's impact on the environment.

REScheck is a free software program developed and provided by the U.S. Department of Energy (DOE) and can be downloaded from the DOE's website. Here are the general steps to download REScheck:

•  Go to the DOE's REScheck website: The REScheck software can be downloaded from the DOE's REScheck website: https://www.energycodes.gov/rescheck
•  Select the appropriate version of REScheck: There are several versions of REScheck available, including desktop software and web-based versions. Choose the version that is most appropriate for your needs.
•  Download the REScheck software: Once you have selected the appropriate version of REScheck, click on the download link and follow the instructions to download and install the software.
•  Verify software compatibility: Make sure your computer meets the system requirements for the REScheck software you are installing.
•  Install the software: Follow the installation instructions provided by the REScheck

Frequently Asked Questions

Is REScheck free?

The U.S. Department of Energy provides REScheck-Web as an online compliance tool. Check the official DOE resource for current access and software information.

Is REScheck the same as COMcheck?

No. REScheck is intended for qualifying residential energy-code compliance, while COMcheck is used for commercial and certain high-rise residential compliance applications.

Does REScheck support the 2024 IECC?

The DOE lists 2024 IECC support in REScheck-Web. The legacy desktop version supports codes only through the 2015 IECC. Verify the applicable code requirements for your jurisdiction before using a particular version.

Does spray foam insulation automatically pass REScheck?

No. Compliance depends on the complete proposed building assembly, the applicable code, and the project inputs. A particular insulation product does not automatically guarantee compliance.

Where can I get help with spray foam equipment?

Contractors can contact Profoam to discuss equipment selection, materials, training, and technical support. For REScheck software support, use the official DOE resources.
