EU Policy News

The second generation of ”CEN EPB” Standards are approaching CEN Enquiry 

The Energy Performance of Buildings Directive (EPBD) refers to European standards to be taken into account in the calculation of the energy performance of buildings and systems. The EU puts strong efforts on the development of European standards, which can enable the harmonisation of diverse methodologies and measures for increasing buildings energy efficiency in the EU member states. 

The second generation of CEN EPB standards will be launched from 2015. The revision work of the existing  standards (more than 40 standards altogether) started in summer 2013, and has included major changes, a few new standards have been added, a couple of standard have merged, a couple have been split into two or more. All standards have changed in their structure: only normative issues will be included in the Standards (EN), and informative issues are put in the Technical Reports (TR).

According to the most recent news from CEN, the public CEN Enquiry for the draft Standards is expected to start in October 2014. 

REHVA has started actions to prepare our profession’s views on CEN EPB standards. REHVA has an official liaison status in three CEN Technical Committees (TC’s 156, 228 and 371), and in several Working Groups (WG’s) under these committees.

New European Commission – Junker merges Energy and Climate change portfolios

President-elect Juncker unveiled the new shape of the next European Commission in September introducing significant changes in the structure and portfolios of the Commission. The new European Commission will be streamlined to focus on tackling the big political challenges Europe is facing among them energy security. A number of portfolios have been reshaped and streamlined.

The new College will have seven Vice-Presidents, six in addition compared to the former structure, which will be in charge of coordinating Project Teams: different commissioners and directorate generals related to the main policy challenges. The Vice-president for Energy Union is Alenka Bratušek, Slovenia’s ex-prime minister, steering and coordinating the Project Team called A Resilient Energy Union with a Forward-Looking Climate Change Policy. The former separate portfolios Energy and Climate Action have been merged under Commissioner Miguel Arias Cañete.

In a next step, the European Parliament (EP) has to give its consent to the entire College of Commissioners. Cañete is expected to face a tough hearing by MEPs at the end of the month. You can follow the online streaming of the EP hearings on EurActive website. Once the European Parliament has given its consent, the European Council formally appoints the European Commission.

Renovation of Buildings - Essential to EU Energy Security and 2030 Debate - Leading industries call for 40% binding energy efficiency target

The 2030 Climate & Energy Package and the EU Energy Security Strategy both feature top of the political agendas ahead of the Ministerial Council on 23rd October. The 28 EU Heads of State have been asked to undertake stress-tests in order to assess their capacity to react in case of disruptions to energy supplies from foreign imports this winter. 

In a letter addressed to the 28 Heads of State, three leading industry associations explain: “A wide-scale deep renovation of the building stock across the EU could drastically reduce EU energy imports with no higher costs than other supply-oriented solutions.  Indeed, given that the building sector is the highest user of gas, reducing our dependence on gas should start with cutting energy waste in buildings”.

Ensuring that a binding energy efficiency target of at least 40% is secured within the 2030 Energy & Climate Package is a pre-requisite to triggering political leadership that will permit an ambitious renovation programme for the EU’s leaky buildings to be rolled out.  With buildings identified as the first area where savings will be realised, setting a 40% binding energy efficiency target represents a golden opportunity to significantly increase energy security in the EU.

MaTrID: Market Transformation Towards Nearly Zero Energy Buildings Through Widespread Use of Integrated Energy Design


Scope of the project: MaTrID aims at supporting the implementation of Nearly Zero Energy Buildings by 2020. In this context the building design phase is of particular importance. Integrated Design (ID) in general is a valuable approach to reduce the complexity of the design process and facilitates the interactions between the members of the design team. ID allows them to provide the best solution for the whole building. It is not limited to energy efficiency and goes beyond this issue. The greatest benefits are provided only if applied in the earliest stages of the project, when changes to the design are still easy to implement. The benefit of EU collaboration is to cross-pollinate best practices among leading European countries (including clients, private industry, etc.). Knowledge transfer among Europe and various actors is the main benefit of MaTrID. For detailed information please visit
