Article #123 - What Should I Do if my Mechanical Equipment is Not an Option in the REScheck Software?

REScheck does not allow trade-offs for ground source heat pumps, forced hot water, and some other systems in the Mechanical tab. The software does allow trade-offs for air source heat pumps, air conditioners, fossil fuel furnaces, and boilers.

Note: You do NOT have to enter mechanical equipment information unless you are using such equipment in a trade-off. Simply do not fill out the Mechanical tab at all - the software will judge compliance based only on your envelope inputs.

Major mechanical systems covered by the IECC.

Although mechanical information is not required for REScheck, building codes do have requirements for mechanical equipment, which may include proper sizing, thermostats, piping insulation, and others. You should meet the appropriate requirements for the mechanical code in your area.

If you are installing a system that is not handled in REScheck, you should do two things to help your code official.

1. Make a note in the Project tab of the software that gives your mechanical system specifics.
2. Attach documents to your REScheck compliance report that provide information about equipment type, efficiency, installation, and sizing.
