A. Section R201.1 Scope. See this section of the IECC and add the following: If the same term is defined in the New Mexico construction codes and in the IECC, the term shall have the meaning given it in the New Mexico construction codes.

B. Section R201.3 Terms defined in other codes. Delete this section of the IECC and substitute with the following: Terms that are not defined in this code but are defined in the NMRBC, NMMC, NMPC, NMEC, or any other New Mexico building code shall have the meanings ascribed to them in those codes.

C. Section R202 General definitions. See this section of the IECC except as provided below.

(1) NMRECC means 2021 New Mexico Residential Energy Conservation Code.

(2) NMRBC means 14.7.3 NMAC, current adopted New Mexico Residential Building Code.

(3) NMPC means current adopted 14.8.2 NMAC, New Mexico Plumbing Code.

(4) NMMC means 14.9.2 NMAC, NMMC current adopted New Mexico Mechanical Code.

(5) NMEC means 14.10.4 NMAC, NMEC current adopted New Mexico Electrical code.

(6) RESCHECK. A document describing the overall efficiency of the insulation of a building which 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 of the proposed project building is compared to the code requirements.

(7) RESNET Software. Is an approved software program to meet the performance requirements of the IECC.

(8) ASTM. Means the American society for testing and materials, an international standards organization that develops and publishes voluntary consensus building technical standards for a wide range of materials utilized in construction.

(9) HERS. Means the home energy rating system index and is the industry standard by which home energy efficiency is measured. It is also the nationally recognized system for inspecting and calculating home energy performance.

(10) Electric vehicle (EV). Add the following definition to the IECC: An automotive-type vehicle for on-road use, such as passenger automobiles, buses, trucks, vans, neighborhood electric vehicles, and electric motorcycles, primarily powered by an electric motor that draws current from a building electrical service, EVSE, a rechargeable storage battery, a fuel cell, a photovoltaic array, or another source of electric current. Plug-in hybrid electric vehicles are electric vehicles that have a second source of motive power. Off-road, self-propelled electric mobile equipment such as industrial trucks, hoists, lifts, transports, golf carts, airline ground support equipment, tractors, boats, and the like are not considered electric vehicles.

(11) Electric vehicle supply equipment (EVSE). Add the following definition to the IECC: Equipment for plug-in power transfer including the ungrounded, grounded and equipment grounding conductors, and the electric vehicle connectors, attachment plugs, personal protection system and all other fittings, devices, power outlets or apparatus installed specifically for the purpose of transferring energy between the premises wiring and the electric vehicle.

(12) Unconditioned space. Add the following definition to the IECC: Space within a building that is not mechanically heated or cooled and is outside the building thermal envelope.

(13) Vapor retarder class. Add the following definition to the IECC: A measure of a material or assembly's ability to limit the amount of moisture that passes through that material or assembly. Vapor retarder class shall be defined using the desiccant method of ASTM E96 as follows:

(a)	class I:	0.1 perm or less;
(b)	class II:	> 0.1 perm	<= 1.0 perm;
(c)	class III:	> 1.0 perm	<= 10 perm.
