Energy efficiency in buildings: Challenges with the European Directive

Energy efficiency in buildings: Challenges with the European Directive
The European Directive on Energy Efficiency in Buildings has been updated to address current climate challenges and promote the integration of renewable energy. This new version, aligned with the European Green Deal and the Renovation Wave, marks a turning point in the transformation of the European building stock. Below, we review the key points introduced by this regulation and how it may impact the future of construction.

1. European framework for energy efficiency in buildings

The approval of the European Green Deal in December 2019 and the Renovation Wave for Europe strategy in October 2020 has prompted a new and in-depth review of the European Energy Performance of Buildings Directive (EPBD).

This review is based on the assumption that buildings are responsible for 40% of energy consumption in the EU and 36% of greenhouse gas (GHG) emissions. Furthermore, only one percent of the building stock is renovated each year, considering that renovation processes improve energy efficiency and reduce emissions.

2. Main objectives of the new directive

The main objective is to reduce GHG emissions and energy consumption in the EU building sector by 2030. Furthermore, the sector aims to be climate-neutral from 2050 onwards. It also aims to renovate less efficient buildings and improve the exchange of information on energy performance.

3. A new aesthetic for buildings

Among the specific measures approved we highlight:
All new buildings must be climate-neutral by 2030 (2028 for public buildings). Technologies such as BIPV, energy storage, and insulation improvements are key to achieving these goals in new construction and renovation. This will be achieved by replacing conventional materials with others that are highly recyclable and produce lower lifecycle emissions.
Residential buildings: Member States will adopt measures to ensure a reduction in the average primary energy used of at least 16% by 2030 and between 20% and 22% by 2035. This measure is primarily aimed at reducing the use of fossil fuels.
Non-residential buildings: Member States will be required to renovate 16% of the least efficient buildings by 2030.
Solar energy installations: If technically and economically appropriate, Member States must implement solar installations in public and non-residential buildings, as well as in all new residential buildings, by 2030.

4. Impact on the Technical Building Code (CTE)

According to the General Council of Technical Architecture of Spain (CGATE), the transposition of this new version of the Directive into Spanish law, or that of any other European country, will entail a modification of the Technical Building Code (CTE). The objective is to make it “more demanding” and “incorporate a higher percentage of renewable energy in buildings.”

Therefore, investing in the integration of renewable energy in buildings through BIPV technology is an effective solution for meeting climate and energy-saving goals. Furthermore, the implementation of other energy-saving and storage systems in buildings is recommended.

5. Renovation of the building stock: a priority

Currently, more than 80% of the building stock in Spain is over 40 years old. This requires new social awareness campaigns and renewed calls for renovation grants. This situation is similar in the rest of Europe, where new European funding is expected to implement these measures.

6. Would you like to implement energy efficiency solutions in your buildings?

At BIREN, we help you adapt your project to the new European regulatory requirements. We integrate technologies such as BIPV, energy storage, and sustainable insulation systems.

What is the European Energy Performance of Buildings Directive (EPBD)?

It is a European Union regulatory framework that establishes minimum energy efficiency requirements for new and existing buildings, promoting emission reduction and the use of renewable energy.

What changes does the latest revision of the EPBD introduce?

It requires all new buildings to be climate-neutral by 2030 (2028 for public buildings), imposes energy renovation targets, and encourages the installation of solar energy.

How does the Directive affect residential buildings?

Member states must ensure a 16% reduction in primary energy consumption by 2030 and a 20-22% reduction by 2035, prioritizing the elimination of fossil fuels and improving insulation.
