T修订后的 建筑能源性能指令 (EU) 2024/1275 — the EPBD — entered into force on 28 May 2024, with Member States required to transpose it into national law by 29 May 2026. It raises the bar from nearly-zero-energy to 零排放 建筑，并使热回收成为合规的核心。

What “Zero-Emission Building” Means
近零能耗建筑（ZEB）具有极高的能源性能，且 无现场化石燃料碳排放, with the small remaining energy covered by on-site or nearby renewables. New buildings must also be “solar-ready.” The earlier nZEB definition (in force since 2020) is replaced for new construction by this stricter ZEB standard.
Where Heat Recovery Fits
- 通风是高性能围护结构中最大的负荷之一，因此回收排风能量是向 ZEB 削减供暖和制冷需求最快的方式。
- 非住宅 ZEB 必须监测并调控 室内空气质量，这维持了使回收具有价值的高外气率。
- Building automation and control systems (BACS) are mandated for HVAC systems above 290 kW from 2024 and above 70 kW from 2029 — ideal for sequencing recovery with economizers.
Link to Supply-Side Recovery
ZEB 围护结构缩减了需求，但剩余的供暖和热水负荷最好用电能满足。将通风回热与以下配对： 区域能源站 or CHP 案例研究 以保持建筑无化石燃料。有关回收义务的跨辖区概览，见以下： building code heat recovery mandate 概述。
Implications for Designers
For specifiers, the EPBD shifts recovery from an optional efficiency measure to part of the default pathway to compliance. As envelopes tighten toward zero-emission performance, ventilation becomes a larger share of the remaining load, so recovering exhaust energy is the most direct way to keep heating and cooling demand down. The directive’s building-automation requirement, BACS above 290 kW from 2024 and above 70 kW from 2029, means recovery should be sequenced with economizers and demand-control ventilation under one controller rather than as a standalone add-on. Member States transpose the directive into national law by May 2026, after which local codes will reference ZEB outcomes, so designing to the stricter ZEB intent now avoids rework. Pairing ventilation recovery with electric heat pumps or a district thermal network keeps the building fossil-free and aligns with the solar-ready and renewable-covering provisions of the standard.
常见问题
What is a Zero-Emission Building under EPBD 2024/1275?
A building with very high energy performance and no on-site fossil-fuel carbon emissions, with the remaining energy covered by renewables.
When must Member States transpose the EPBD?
By 29 May 2026, with new public buildings at zero emission from 2028 and all new buildings from 2030.
Where does heat recovery fit in ZEB compliance?
Ventilation is a major load in a tight envelope, so exhaust recovery is the fastest route to cutting heating and cooling demand.
How does EPBD relate to Ecodesign?
Ecodesign sets equipment efficiency floors that support the EPBD's building-level zero-emission intent.
