Rescheck Info

Designers as well as builders and/or contractors use the RESCheck to ascertain whether their new homes, additions, or alterations conform to the IECC regulations and few other state energy codes.

Additionally, RESCheck enables building officials, plan checkers and inspectors to make energy compliance determinations in a prompt manner on low-rise dwellings that satisfy the code requirements.

One application of REScheck is for insulation and window trade-offs in stand-alone residential one- and two-family buildings or three stories or less above grade within multi-family buildings such as apartments, townhouses, or condominiums.

To determine the building’s overall UA value REScheck employs a simple U-factor x Area (UA) calculation for each building assembly.

The UA for your building is compared with a UA that would occur if your building was code-compliance. 

According to the program’s report, if the total heat loss (expressed as a UA) through your building envelope does not exceed total heat loss from this building complying with the code being checked on; then it means that your structure meets the code.


To determine if new houses, addenda as well as changes meet the International Energy Conservation Code (IECC) or National Energy Code is what Rescheck does. It simplifies compliance determinations for building officials, plan checkers and inspectors by enabling them to determine in a straightforward manner if a low-rise dwelling complies with the code.

The same way as new construction, additions are checked for compliance by Rescheck. When entering an addition, one only needs to show the new parts of the building in the software. To determine compliance, Rescheck trade-offs envelope assemblies.

Rescheck is suited for insulation and window tradeoff calculations in one and two-story family buildings and multi-family buildings less than three stories above grade, such as apartments, condos, and townhouses.
