The Energy Efficiency Directive (Directive 2012/27/EU, EED), adopted in 2012, in its Article 4, requires EU Member States (MS) to establish a long-term strategy for mobilising investment in the renovation of the national stock of residential and commercial buildings, both public and private.
As required by the EED, the first version of the strategy was published by each Member State in 2014 and this has to be updated every three years and submitted to the Commission as part of the National Energy Efficiency Action Plans (NEEAPs). Therefore Member States have submitted their updates on their long-term building renovation strategies in 2017. This report is a follow-up of the assessment of the first building renovation strategies, published by the JRC in 2016 (Castellazzi et al. 2016).
Similarly to the previous report, this study provides an overview of the EU's national building stocks (e.g. energy performance, etc.), highlighting the availability of data and data gaps. It also assesses the ambition of the planned strategies as well as the appropriateness of the policies and measures to achieve them. The study also identifies good practice examples.
Beyond the assessment of the updated strategies, this report also considers how some of the new elements, which will be required in the future as part of the long-term renovation strategies under the new Article 2a of the EPBD, namely the long-term vision of a decarbonised buildings stock by 2050, the domestically established measurable progress indicators, the indicative milestones for 2030, 2040 and 2050, the alleviation of energy poverty and the mobilisation of investments, are already present and addressed in the current strategies.
Long-term strategies are intended to support the transformation towards a national building stock that is highly-efficient and decarbonised by 2050. Long-term strategies must be underpinned by a roadmap which sets out measures and domestically established measurable progress indicators. The measures must facilitate the cost-effective transformation of existing buildings into nearly zero-energy buildings. The indicators will help measure progress towards the long-term 2050 goal of reducing greenhouse gas emissions in the Union by 80-95% compared to 1990.
Member States must also define indicative milestones for 2030, 2040 and 2050 and must specify how they contribute to achieving the Union's energy efficiency targets set out in the Energy Efficiency Directive (Directive 2012/27/EU). Finally, to support the mobilisation of investment, renovation which is necessary to achieve these objectives, Member States must facilitate access to mechanisms for the aggregation of projects, the reducing of the perceived risk of energy efficiency operations for investors, the use of public funding to leverage additional private-sector investment, guiding investments into an energy efficient public building stock, and accessible and transparent advisory tools.
