Manual J and Rescheck Reports
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. If the total heat loss (represented as a UA) through the envelope of your building does not exceed the total heat loss from the same building conforming to the code, the software generates a report that declares your building is compliant with the code.
What is a Rescheck UA tradeoff?
The UA alternative, commonly known as ResCheck path, also converts everything to a U-value but because it is the sum of u-factor times assembly area, it will allow trade-offs between other items that may be converted to a u-value, as long as the total UA is less than or equal to a prescriptive house (U= 1/R).
Completing your RESchecks is a service provided by REScheck Review.
