SPECIAL REPORT

LEEDuser’s viewpoint

Frank advice from LEED experts

LEED is changing all the time, and every project is unique. Even seasoned professionals can miss a critical detail and lose a credit or even a prerequisite at the last minute. Our expert advice guides our LEEDuser Premium members and saves you valuable time.

Credit language

Intent

This credit applies to projects registered prior to March 1, 2024. Projects registered after March 1, 2024 are subject to the v4 2024 Update.

To achieve increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic harms associated with excessive energy use.

Requirements

Establish an energy performance target no later than the schematic design phase. The target must be established as kBtu per square foot-year (kWh per square meter-year) of source energy use.

Choose one of the options below.

Option 1. Tenant-level energy simulation (1–25 points)

Analyze efficiency measures during the design process and account for the results in design decision-making. Analysis can include energy simulation of efficiency opportunities, energy simulation analyses for similar projects, or published data from energy analyses performed for similar projects (such as AEDGs).

Analyze efficiency measures focused on load reduction and HVAC-related strategies; passive measures are acceptable. Project the potential energy savings and cost implications for all affected systems.

Follow the criteria in EA Prerequisite Minimum Energy Performance to demonstrate a percentage improvement in the proposed tenant project performance rating compared with the baseline.

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.

Step 1. Evaluate Base Building Systems for AEDG Compliance -

Delete "four" from the first sentence that begins "Determine whether one of the..."

Add the sentence below after the sentence "AEDG criteria apply to the base building property, not the tenant space.":

"(Exception: Building opaque envelope and glazing system options may be applied to the tenant space using the AEDG if the building meets all AEDG Criteria except the gross floor area. For example, an office space in a 120,000 ft2 office building may document points for meeting the AEDG prescriptive opaque envelope and glazing system requirements even though the building gross area exceeds the 100,000 ft2 AEDG criteria)."

7/1/2014 – Updated: 3/29/2018

Regional ACP

Description of change:

Add the following as a USGBC-approved equivalent standard for projects outside the U.S.

"Projects in Canada may instead demonstrate a percentage improvement in the proposed building performance rating compared with the baseline according to the National Energy Code for Buildings (NECB) 2011. The same percentage improvement in energy performance is required to meet the Prerequisite, and the same points for percentage improvement in energy performance are applicable for the Credit.

The following conditions (where applicable) must be met. Note that unless otherwise noted, CanQUEST (the Canadian energy modelling software based on eQUEST that performs NECB 2011 compliance runs) does not implement these conditions correctly and would require corresponding modifications to the Reference case.

1. Comply with mandatory requirements of ASHRAE 90.1-2010
ASHRAE 90.1-2010 mandatory requirements must be met, in addition to the performance path limitations referenced in the NECB 2011 Sections 3.4.1.2, 5.4.1.2 and 6.4.1.2. In cases where ASHRAE and the NECBC reference requirements concerning the same item, the more stringent requirement shall be adhered to.

2. Apply fenestration area convention similar to ASHRAE 90.1-2010
Maintain the same FWR (as defined by NECB, including doors) for the Reference as exists in the Proposed Design, up to the prescribed maximum. If the Proposed Design’s FWR exceeds the prescribed FWR, scale down the fenestrations in the Reference case accordingly.

3. Apply skylight area convention similar to ASHRAE 90.1-2010
Maintain the same SRR for the Reference as exists in the Proposed Design, up to the prescribed 5% maximum. If the Proposed Design’s SRR exceeds 5%, scale down the skylights in the Reference case accordingly.

4. Model proposed and reference outside air similar to ASHRAE 90.1-2010
Proposed and reference (baseline) outside air rates shall be modelled as per ASHRAE 90.1 – 2010 (G3.1.2.6).

5. Apply ASHRAE kitchen exhaust demand ventilation requirements
Provide for the same demand ventilation requirements as described in ASHRAE Appendix G3.1.1.d.

6. Apply ASHRAE’s chiller heat recovery requirements
Provide for the same chiller heat recovery requirements as applies to ASHRAE.

7. Apply supply air temperature reset controlled based on warmest zone
Reset the minimum supply air temperature to satisfy the cooling requirements of the warmest zone, as stipulated in NECB Section 5.2.8.8. Note that this control setting is already corrected in CanQUEST for the Reference case.

8. Account for uninsulated structural penetrations if they exceed 2% of net wall area
The 2% allowance may be applied, but based on the net opaque wall area, not the entire building envelope area.

9. Follow ASHRAE/LEED rules for renovations to existing buildings
Model existing components consistent with ASHRAE and LEED provisions.

10. Account for all anticipated energy use in building
Fully account for all energy end-uses in the energy performance modeling."

LEED Interpretation

Inquiry:

Can commercial interiors projects use the existing envelope in the baseline energy model in Option 1 of LEED v4 ID+C Energy and Atmosphere (EA) prerequisite Minimum Energy Performance and EA credit Optimize Energy Performance?

Ruling:

Yes. As an alternative to modeling the ASHRAE 90.1 Appendix G prescriptive new construction envelope requirements in the Baseline, project teams may use the existing envelope in the baseline energy model per ASHRAE 90.1-2010 Table G.3.1.5 (baseline) f, subject to revised percentage improvement thresholds for (EA) prerequisite Minimum Energy Performance and EA credit Optimize Energy Performance outlined below.

Project teams modeling the existing envelope in the baseline must demonstrate 5% performance improvement under EA prerequisite Minimum Energy Performance, and must demonstrate a 2% performance improvement above established performance thresholds in EA credit Optimize Energy Performance to earn the corresponding number of points. For example, project teams must demonstrate 6% performance improvement to achieve 4 points, 7% performance improvement to achieve 6 points, 8% performance improvement to achieve 8 points, etc. Project teams must demonstrate 30% performance improvement to achieve 25 points under EA credit Optimize Energy Performance.

Update March 1, 2024:
This LEED Interpretation is not applicable to projects subject to the LEED v4 2024 Update because the allowance is directly incorporated into the v4 2024 Update prerequisite and credit requirements.

LEED Interpretation

Inquiry:

Our project is subject to ASHRAE Standard 90.1-2013 for code compliance. To pursue Option 1: Whole Building Simulation, is there a methodology for documenting additional energy performance for LEED v4 projects regulated by ASHRAE Standard 90.1-2013?

Ruling:

Yes, projects applying Option 1: Whole Building Simulation, and regulated by ASHRAE Standard 90.1-2013 may document additional energy performance improvement under LEED v4 EA credit Optimize Energy Performance as described below. The Appendix G modeling method must be used for the LEED submission, even if the Energy Cost Budget method is used to document local code compliance.

Projects may calculate the Equivalent ASHRAE 90.1-2010 Performance improvement as:
Equivalent performance Improvement = % better than ASHRAE 90.1-2013 + Additional Percent Savings

Projects subject to the v4 2024 update may apply the additional percent savings to each metric (cost, source energy, greenhouse gas emissions)

Where Additional Percent Savings is shown in Table 1:

Table 1: Additional Percent Savings for ASHRAE 90.1-2013

Project Type¹ Additional Percent Savings
NC-Office 5%
NC-Retail (except restaurant/grocery) 5%

LEED Interpretation

Inquiry:

The ENERGY STAR program is continuously releasing new and updated standards for products. Project teams may be unaware that a product they are purchasing is subject to an ENERGY STAR standard. Can a project team exclude equipment covered by recently developed ENERGY STAR product specifications from the prerequisite and credit calculations? If all equipment must be included, are teams required to use the rated power or can teams “discount” the rated power to reflect average consumption or actual operating power demand? And how should international projects apply this to new ENERGY STAR product specifications or other equipment or appliances where an ENERGY STAR option is not available locally?

Ruling:

As required in LEED Interpretation 10044, all equipment classified as eligible by ENERGY STAR must be included in the calculations. Equipment that is procured within two years of the effective date of the first (i.e. Version 1.0) ENERGY STAR product specification for that equipment category may be included or excluded at the discretion of the project team; however, all equipment within that category must be included or excluded consistently. Refer to the ENERGY STAR product specification(s) for the effective date.

Calculations may be completed using either the rated power OR the average annual power consumption, but the metric selected must be consistent for all equipment included in the calculations. For the purposes of demonstrating equivalency to the ENERGY STAR product specification by average annual power consumption, equipment purchased may use no more than the average annual energy consumption of the equivalent ENERGY STAR-qualified product as determined by the appropriate ENERGY STAR savings calculator. The average annual power consumption for purchased equipment may be demonstrated by manufacturer documentation or calculated from actual equipment operating data and anticipated use profiles.

For Uninterruptible Power Supply (UPS) equipment:

If using the rated power methodology, the UPS “rated power” for the LEED Calculation may optionally be derated to 35% of the UPS Rated Output Power to more accurately reflect the relative energy usage associated with UPS equipment compared to other Energy Star equipment.

If using the average annual power consumption methodology, the UPS average annual power consumption (in units of kWh/year) shall be calculated as:
UPS Annual Power Consumption = 6,600 x Power x (1-Eff_AVGMIN)

Where:

Power is the UPS Rated Output Power in units of kW.

Eff_AVGMIN is determined consistently with the ENERGY STAR® Program Requirements, or 93.7% if unknown.

For projects located outside of the United States, the following approved standards may be used in place of ENERGY STAR for equipment categories covered by these standards: EU ENERGY STAR, TCO, Blue Angel. Additionally, equipment classified as eligible by ENERGY STAR but not ENERGY STAR-qualified may be deemed equivalent if the equipment has been labeled by a local energy label and has been rated by the labeling program to use no more than the average annual energy consumption of the equivalent ENERGY STAR-qualified product as determined by the appropriate ENERGY STAR savings calculator.

Updated 3/1/2024 to clarify the LI is not applicable to the v4 2024 update.

Updated 01/05/18 for rating system version applicability and to provide additional calculation options for Uninterruptible Power Supply equipment.
