702 Performance Path

702.1 - Point Allocation

Points from Section 702 (Performance Path) shall not be combined with points from Section 703 (Prescriptive Path) or Section 704 (ERI Target Path).

702.2 - Energy Performance Levels

702.2.1: ICC IECC analysis

Energy efficiency features are implemented to achieve energy cost or source energy performance that meets the ICC IECC. A documented analysis using software in accordance with ICC IECC, Section R405, or ICC IECC Section C407.2 through C407.5, applied as defined in the ICC IECC, is required.

Required Documentation

Energy performance report showing energy savings levels above ICC IECC. See Energy Efficiency Modeling Policy for details on eligible software and accepted approaches. For multifamily projects employing building average or unit-by-unit modeling approaches, submit analysis showing the units modeled and corresponding performance. This can be submitted as an Excel table or another file format.

702.2.2: Energy performance analysis (points per formula; Points = 30 + (percent above NGBS Reference Home) * 2)

Energy savings levels above the ICC IECC are determined through an analysis that includes improvements in building envelope, air infiltration, heating system efficiencies, cooling system efficiencies, duct sealing, water heating system efficiencies, lighting, appliances, and on-site renewable energy.

Multifamily Building Note: Modeling is completed building-wide using one of the following methods: whole building energy modeling, a unit-by-unit approach, or a building average of a unit-by-unit approach.

Required Documentation

Energy performance report showing energy savings levels above ICC IECC. See Energy Efficiency Modeling Policy for details on eligible software and accepted approaches. For multifamily projects employing building average or unit-by-unit modeling approaches, submit analysis showing the units modeled and corresponding performance. This can be submitted as an Excel table or another file format. The 2018 IECC must be the basis for this analysis.

Ekotrope has a 2020 NGBS Green report that demonstrates compliance with this practice. RemRate is working on developing a 2020 NGBS report.

702.2.3: Tropical standard reference design

For the Tropical Climate Zone, the standard reference design shall use the specifications in IECC Section R401.2.1 (Tropical Zone).
