EPBD

EPBD Energy Performance of Buildings Directive building EU heat transition Energy Efficiency

EPBD stands for Energy Performance of Buildings Directive, in German Richtlinie über die Gesamtenergieeffizienz von Gebäuden. The recast version, Directive (EU) 2024/1275 of 24 April 2024, is the one that now applies. It was published in the Official Journal of the EU on 8 May 2024. It repeals and replaces the predecessor Directive 2010/31/EU with effect from 30 May 2026. Its stated goal is a zero-emission building stock by 2050. The directive applies to new and existing buildings. It concerns both energy efficiency and the integration of renewable energy.

The core concept is the energy performance of a building. This does not mean only the space heating demand, which is determined by the building envelope. It means the calculated or measured amount of energy for typical operation: space heating, cooling, hot water, ventilation, built-in lighting and other technical building systems. According to the directive, the calculation methodology is also to take into account on-site renewable energy, building automation, heat recovery and smart solutions. The Member States may adapt it nationally and regionally. The result is expressed through indicators such as primary energy demand, final energy demand, greenhouse gas emissions or efficiency classes.

A directive, not a directly applicable detailed law

The EPBD is often treated as if it directly determined which individual building has to be renovated, when and how. That does not reflect its legal nature. An EU directive is addressed to the Member States: it sets targets and minimum requirements and leaves leeway in implementation. Owners are, as a rule, only bound by national implementing law. Under Article 35, certain new provisions had to be transposed by 1 January 2025. Most of it was due by 29 May 2026.

In Germany, implementation has so far run mainly through the Gebäudeenergiegesetz (Building Energy Act). It was fundamentally reformed in 2026 and is now called the Gebäudemodernisierungsgesetz (GModG, Buildings Modernisation Act). The act was promulgated in the Federal Law Gazette on 28 July 2026, and its main new provisions have applied since 29 July 2026. The obligation to use 65 percent renewable energy when replacing a heating system has been dropped. This shows the leeway: the directive sets targets, while the national heating rule is a separate political decision. According to the BDEW, the EPBD parts, such as minimum requirements for non-residential buildings and changes to the energy performance certificate, only enter into force on the first day of the month six months after promulgation, i.e. presumably at the beginning of 2027. In addition, funding conditions, municipal heat planning and further rules, for example on charging infrastructure, have an effect.

Key requirements of the 2024 recast

  • Zero-emission new buildings: New buildings occupied or owned by public bodies must be zero-emission buildings from 2028, and all new buildings from 2030. Such a building must be highly efficient, must not cause any on-site carbon emissions from fossil fuels, and may have at most very low operational greenhouse gas emissions.

  • Life-cycle perspective: For new buildings, the global warming potential over the life cycle (GWP) must be calculated, first for large new buildings over 1000 m², later for all new buildings by 2030. In addition to operation, this brings the embodied emissions of construction products into view. Annex III of the directive has since been replaced by a delegated act that has applied since 24 May 2026.

  • Minimum requirements for non-residential buildings: Each Member State sets threshold values. From 2030, all non-residential buildings must perform better than the worst-performing 16 percent of the national stock, and from 2033 better than the worst-performing 26 percent. The reference is the stock as of 1 January 2020. In practice, this triggers the renovation of the least efficient buildings.

  • Residential buildings: There is no EU-wide renovation obligation for the individual house here. What is required is a national trajectory that gradually lowers the average primary energy use of the entire residential building stock. The Member States decide which instruments they use to achieve this.

  • National building renovation plans: They contain an overview of the building stock, roadmaps with targets for 2030, 2040 and 2050, and information on investment needs and financing. The targets include renovation rates, lower primary energy consumption and emissions, and less energy poverty.

  • Further instruments: New buildings are to make optimal use of their solar potential, and solar installations on buildings are being introduced step by step. In addition there are renovation passports, requirements for technical building systems, charging points and bicycle parking spaces, a smart readiness indicator for buildings, access to building data, one-stop shops, and inspections of heating, ventilation and air-conditioning systems. All energy performance certificates must be uploaded to a national database, and the efficiency class is to appear in sale and rental advertisements.

Distinction from the energy performance certificate, building standards and heating law

An energy performance certificate describes a specific building. The EPBD sets out the rules by which the states must organise such certificates and minimum requirements. The recast is intended to make certificates more comparable across Europe, among other things through a uniform class scale and an independent control system. Building standards such as efficiency house (Effizienzhaus), nearly zero-energy building or zero-emission building are also not the same thing as the directive. They are categories derived from EU requirements or national law. Their exact limit values depend on national calculation methods.

Heating law regulates individual heat generators. The EPBD, by contrast, looks at the building as an energy unit made up of envelope, building systems and energy supply. A heat pump also works in a poorly insulated house, but needs more electricity and a higher output there. Conversely, better insulation reduces demand but does not by itself make the heat supply climate-neutral. The directive requires both to be considered together. It addresses fossil-fuel boilers directly: the Member States are also to inform owners and tenants about replacing such boilers with more sustainable alternatives.

Why the EPBD matters for the power system

According to the recitals of the directive, buildings account for 40 percent of the EU's final energy consumption and 36 percent of energy-related greenhouse gas emissions. Natural gas covers around 39 percent of the energy consumption for space heating in residential buildings. If oil and gas heating systems are replaced by heat pumps, part of the heat demand shifts into the electricity sector. For the grid, what then matters less is the annual volume than the question of when how much power is drawn. Cold winter evenings, when many heat pumps run at the same time, put particular strain on the distribution grid. A well-designed heat pump in an efficient building loads the grid very differently from a tightly sized system in an unrenovated house with high flow temperatures.

Buildings can consume, store and generate electricity. This includes photovoltaics on the roof, battery and hot water storage, controllable charging points and building automation. The EPBD expressly promotes these elements: solar use, storage of renewable energy in the building, charging infrastructure and smart control. This makes the building a possible source of flexibility. The relationship is not linear, however. A house with its own solar installation can generate a lot of electricity over the year and still need grid power on dark winter evenings. Annual balances explain this only incompletely.

Typical misunderstandings

First: calculated efficiency is not the same as actual consumption. Many indicators are based on standardised assumptions. A frugal household in an inefficient building can therefore consume less than a comfort-oriented household in a good building. The recast expressly also allows measured energy values to verify results and make them comparable. For billing, grid load and real emissions, user behaviour, weather and operational management nevertheless remain decisive.

Second: the EPBD does not automatically reduce housing costs. Renovations reduce consumption and emissions in the long term, but initially cost money. For rental housing, this burden is distributed differently than for owner-occupied property. The directive requires minimum requirements to be accompanied by technical assistance and financing, especially for vulnerable households. Whether efficiency gains reach the occupants, however, depends on national tenancy law, funding and energy prices.

Third: the building stock cannot be replaced like a vehicle fleet. Buildings are long-lived, regionally diverse and owned by a great many owners. How fast renovation proceeds depends on skilled-trades capacity, financing, materials, permits and heritage protection. Fourth: the directive does not contain a binding renovation obligation for every individual residential house. For residential buildings it requires a target trajectory for the entire stock. Strict minimum requirements at EU level apply only to non-residential buildings, and even there only after national implementation.

Institutional function and limits

The EPBD makes the building sector measurable and politically steerable. Renovation plans, minimum requirements, energy performance certificates, databases and requirements for building technology serve this purpose. This information function is often underestimated. The directive requires, for example, that local authorities be given access to the efficiency data of the buildings in their area, which they need for heating and cooling plans. Without comparable indicators, funding, investment and progress can hardly be assessed.

At the same time, the EPBD does not answer all questions of the building sector. It regulates land policy, living space, construction costs, supply chains and municipal infrastructure only at the margins. Whether district heating, a heat pump, biomass or another solution makes sense locally cannot be read off a single indicator. For this, building condition, heat and electricity grids, local generation, costs and emission pathways must be considered together. The directive is complemented by further EU rules, such as the Energy Efficiency Directive and the Renewable Energy Directive, as well as emissions trading for fuels in buildings.

For the heat transition, the EPBD is an organising framework, not a single technical lever. It steers building policy away from isolated individual measures and towards long-term requirements for efficiency, renewable supply, data quality and renovation planning. It only becomes effective when its requirements are translated into national law, financeable renovation pathways, reliable standards and sufficient implementation capacity.
