LEED 能量回收得分

Energy recovery contributes to the Energy & Atmosphere (EA) credits that dominate LEED scoring. Whether you register under LEED v4.1 (still open in 2026) or the newer LEED v5 (2025–2030 cycle), ventilation recovery reduces the modeled energy use that the credit is scored on.

LEED v4.1 BD+C

• EA Credit: Optimize Energy Performance is worth up to 18 points, scored from the ASHRAE 90.1 energy model (split since 2024 into 9 points energy efficiency + 9 points GHG).
• A high-effectiveness recovery core lowers the heating and cooling loads in that model, directly raising the percentage improvement over baseline.
• EA Prerequisite: Minimum Energy Performance is the gate — and 90.1’s recovery rule (see ASHRAE 90.1 requirements) is part of that baseline.

LEED v5 BD+C (what changed)

Area	v4.1	v5
Enhanced Energy Efficiency credit	up to 18 pts	1–10 pts, prescriptive path on ASHRAE 90.1-2022 §11
Electrification credit	none	new (favors heat pumps over combustion)
Reduce Peak Thermal Loads	none	new — ventilation energy recovery is an explicit measure
Required standard	90.1-2019/2022	90.1-2022 required after 1 Jan 2028

How to Use Recovery for Points

1. Model the building with and without the recovery core; the delta is your saving.
2. For v5, count recovery under both the Enhanced Energy Efficiency prescriptive measures and the new Peak Thermal Loads credit.
3. Pair recovery with a high-efficiency heat pump or 高温热泵 to support the Electrification credit and cut on-site combustion.

Because v5 rewards decarbonization over cost, an electrically driven recovery-plus-heat-pump strategy scores better than a gas-fired reheat baseline. Document the modeled effectiveness using the recognized test standards.

Modeling and Documentation

The credit is won or lost in the energy model, so the recovery core’s modeled effectiveness must use the same test basis the rating system expects. In v4.1 the savings show up as a percentage improvement over the ASHRAE 90.1 baseline, where the baseline itself already includes the 90.1 recovery rule, so a project must beat that baseline, not merely meet it. In v5 the credit is split and recovery appears under both Enhanced Energy Efficiency, prescriptive on 90.1-2022 section 11, and the new Reduce Peak Thermal Loads measure, while the Electrification credit rewards pairing recovery with heat pumps over combustion. Document the core’s measured effectiveness from a recognized standard, the system boundary, and the baseline assumptions; reviewers increasingly ask for the model inputs. Coordinating recovery with an electrically driven heat-pump strategy also strengthens the decarbonization narrative that v5 scores heavily.

常见问题

How does energy recovery earn LEED points?
By lowering modeled heating and cooling loads, raising the percentage energy improvement over the ASHRAE 90.1 baseline.

What changed in LEED v5 versus v4.1?
v5 splits the efficiency credit, adds an Electrification credit, and adds a Reduce Peak Thermal Loads credit that explicitly rewards ventilation recovery.

Is meeting the ASHRAE 90.1 recovery rule enough for LEED?
No. The baseline already includes that rule, so the project must beat the baseline, not merely meet the code minimum.

Should recovery be paired with heat pumps for LEED?
Yes. An electrically driven recovery-plus-heat-pump strategy supports the Electrification credit and cuts on-site combustion.
