Intent

To improve the home’s overall energy performance and reduce its greenhouse gas emissions.

Requirements

Follow the criteria in EA Prerequisite Minimum Energy Performance to demonstrate a percentage improvement in the proposed building’s performance compared with the baseline building performance of ASHRAE 90.1–2010, or USGBC-approved equivalent standard for projects outside the U.S. Points are awarded according to Table 5.

AND

Earn 1 point for every 4% decrease in conditioned floor area compared with the ENERGY STAR for Homes, version 3, reference home (Table 1). Buildings that are larger than the reference home lose 1 point for every 4% increase in conditioned floor area.

Projects cannot exceed the maximum number of points in the EA section.

  1 2 3 4 5 6 7 8 or more
Floor area (square feet) 1,000 1,600 2,200 2,800 3,400 4,000 4,600 + 600 ft2 per additional bedroom
Floor area (square meters) 93 148 204 260 315 371 426 + 55.6 square meters per additional bedroom

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

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.

Description of change:
Current language reads: Follow the criteria in EA Prerequisite Performance for Energy Star Homes to demonstrate a percentage improvement in the proposed building’s performance compared with the baseline building performance of ASHRAE 90.1–2010, or USGBC-approved equivalent standard for projects outside the U.S. Points are awarded according to Table 5.

Replace the term "EA Prerequisite Performance for Energy Star Homes" with the following: "EA Prerequisite Minimum Energy Performance."

LEED Interpretation
Inquiry:

Our multifamily project is pursuing ENERGY STAR Multifamily New Construction Certification (Version 1, 1.1, OR-WA 1.2). Can this be used in lieu of ASHRAE 90.1-2010 (or approved equivalent standard) to demonstrate energy performance for the project?

Ruling:

Projects that certify to ENERGY STAR Multifamily New Construction Certification under version 1 are considered equivalent to a 5% improvement beyond ASHRAE 90.1-2010 Appendix G. Projects that certify under version 1.1 and 1.2 are considered equivalent to a 15% improvement beyond ASHRAE 90.1-2010 Appendix G. The Home Size Adjuster shall not be used to adjust the number of points awarded when using this ENERGY STAR MFNC equivalency path.

Projects 4 or more stories achieving ENERGY STAR Multifamily New Construction Certification Version 1, 1.1, or 1.2, where the combined retail or commercial space is less than 20% of the conditioned floor, area may follow the LEED BD+C: Homes Annual Energy Use requirements to document up to 29 points (where ERI replaces instances of HERS). The Home Size Adjuster shall not be used to adjust the number of points awarded when using this path.

LEED Interpretation
Inquiry:

Our multifamily project is pursuing Passive House certification. Is there an equivalency to 90.1-2010 for Passive House certified multifamily projects?

Ruling:

Yes, multifamily projects that achieve Passive House certification through the Passive House Institute (PHI) or PHIUS+ certification through the Passive House Institute US (PHIUS) certification may document additional energy performance improvement compared to 90.1-2010, as described below.

Percent Above ASHRAE 90.1-2010

Climate Zones 1A, 2A: 24%
Climate Zones 2B, 3B: 27%
Climate Zones 3A, 4: 31%
Climate Zones 4C, 5: 30%
Climate Zones 6, 7, 8: 38%

Campus Applicable
No
Internationally Applicable:

4/5/2016
LEED Interpretation
Inquiry:

Appliance manufacturers are no longer reporting MEF or WF information and are instead reporting Integrated Modified Energy Factor (IMEF) and Integrated Water Factor (IWF) for any residentially classified washing machines. ENERGY STAR appliances made this change in a recent update.

How should projects apply LEED credits that reference the old MEF and WF use the updated IMEF and IWF?

Ruling:

There is no direct equivalency between MEF and IMEF, nor WF and IWF. Projects should use the ENERGY STAR performance thresholds for IMEF and IWF to meet LEED credit requirements.

Campus Applicable
No
Internationally Applicable:
No
