What Is A ResCheck?

Are you curious to know what is a rescheck? You have come to the right place as I am going to tell you everything about a rescheck in a very simple explanation. Without further discussion let’s begin to know what is a rescheck?

In the realm of construction and building compliance, ResCheck holds a significant position. But what exactly is ResCheck and why does it matter in the world of construction and renovation?

What Is A ResCheck?

ResCheck is a software tool developed by the U.S. Department of Energy (DOE) to verify if a proposed residential building or renovation project meets the energy efficiency requirements outlined in the International Energy Conservation Code (IECC). Its primary goal is to ensure that the energy usage of a building complies with the standards set by the IECC, specifically in regards to thermal performance and insulation levels.

The Importance Of ResCheck

  • Energy Efficiency Compliance: ResCheck serves as a tool to evaluate and confirm that a building’s design or modifications align with the energy efficiency criteria mandated by the IECC. It ensures that the structure will meet or exceed the minimum requirements for energy conservation.
  • Regulatory Adherence: Many local building codes and jurisdictions require ResCheck compliance as part of the permit approval process. It helps ensure that buildings are constructed or renovated in a way that minimizes energy consumption and reduces environmental impact.
  • Thermal Performance Evaluation: ResCheck assesses various aspects of a building’s thermal performance, including insulation levels, window efficiency, and overall energy consumption, to ensure they meet the standards set by the code.

How ResCheck Works?

  • Inputting Data: Users input specific details about the building’s construction materials, insulation types, window specifications, and other relevant data into the ResCheck software.
  • Analysis and Verification: The software then processes this information to determine if the proposed building or renovation complies with the energy efficiency requirements specified by the IECC.
  • Compliance Reporting: ResCheck generates a report detailing whether the project meets the required standards. This report is often necessary for obtaining building permits and demonstrating compliance with energy codes.

The Role In Construction And Renovation Projects

For architects, builders, and contractors, ResCheck is an essential tool in ensuring that their designs and constructions meet the necessary energy efficiency standards. It’s not only a regulatory requirement but also a means to create more sustainable and environmentally friendly structures.


In the ever-evolving landscape of construction and building compliance, ResCheck stands as a crucial instrument for verifying and confirming the energy efficiency of residential buildings. By ensuring adherence to energy codes and standards, ResCheck contributes to the creation of more sustainable and environmentally conscious structures.

As the focus on energy conservation intensifies, the role of ResCheck in construction and renovation projects remains pivotal, shaping the way buildings are designed and constructed to be more energy-efficient and environmentally friendly.


Who Completes A ResCheck?

The designer, architect, builder, home inspector, and homeowner all have a responsibility to make sure what is proposed to be built is insulated the best it possibly can be. Many times we find at REScheck.info that having a more efficient home does not cost anymore than building an inefficient home.

What Information Is Needed For A ResCheck?

With the software that I use, it requires entering the total square footage of the ceiling, the total square footage of the windows, and total square footage of the walls and floor. I then enter the R-value of each individual area of the house.

What Is A ResCheck For Insulation?

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).

What Is The ResCheck Method Of Compliance?

REScheck works by performing a simple U-factor x Area (UA) calculation for each building assembly to determine the overall UA of a building. The UA that would result from a building conforming to the code requirements is compared against the UA for your building.
