Mid-Rise-v4 EAc1: Annual energy use 1-30 points

Projects that certify to ENERGY STAR Multifamily New Construction (ESMFNC) may claim credit under Path 1 or Path 2, and document additional points for Home Size Adjuster as indicated below. Projects must use a version and revision applicable to the project location at the time of permitting in accordance with the “ENERGY STAR MFNC Applicable Program Requirements, Versions, and Revisions by Location”. Projects that achieve ESMFNC certification under version 1.1 or later are automatically compliant with the EA Prerequisite: Minimum Energy Performance Commissioning or Testing and Verification requirements.

Path 1. Equivalent ASHRAE 90.1-2010 Appendix G performance improvement

Projects may document achievement of points for the equivalent ASHRAE 90.1-2010 Appendix G improvement indicated in Table 1 for each metric.

Path 2. ERI Path

Projects certifying under the ENERGY STAR MFNC ERI path from version 1.1 or later with combined retail or commercial space less than 20,000 square feet AND less than 20% of the conditioned floor may follow the LEED BD+C: Homes Annual Energy Use requirements to document up to 29 points (where ERI replaces instances of HERS).

AND

Home Size Adjuster (Paths 1 and 2)

Earn 1 point for every 7% decrease in conditioned floor area compared with the ENERGY STAR for Homes, version 3, reference home (Table 2). Buildings that are larger than the reference home lose 1 point for every 7% increase in conditioned floor area. Projects cannot exceed the maximum number of points in the EA section.

For multifamily buildings, home size includes only in-unit space.

International projects:
International projects that are ineligible to achieve ENERGY STAR certification may document achievement of the ENERGY STAR Multifamily New Construction certification requirements rather than submitting the ENERGY STAR MFNC Certificate. Projects registered after March 1, 2024 must use MFNC National v1.1 Rev. 03 or later or MFNC National v1.2 Rev. 03 or later. All Mandatory and Prescriptive requirements apply, except for analogous requirements with LEED approved exceptions for International projects (e.g. LEED Interpretation 10443 allowing exceptions to HERS Qualified Energy Raters, LEED Interpretation 10444 allowing visual inspections in lieu of HERS testing, etc.).

Updated March 1, 2024 to align with changes in the LEED v4 Energy Update and to recognize credit for Home Size Adjuster.
