TABLE: how the ALDREN outcomes could help to fulfil the new requirements of the amended EPBD

The ALDREN project (Alliance for Deep Renovation in buildings) is the extended development and the implementation of a common European Voluntary Certification Scheme (EVCS) for non-residential buildings based on the EPBD Art. 11 (9) and CEN / ISO standards.

 

As a Coordination and Support Action (CSA) of the H2020 funding program of the EU, the main goal of ALDREN is to encourage the construction sector value chain stakeholders to undertake deep renovation projects on their properties. Issuing completed and verified Energy Performance Certificates (EPC) before and after renovation, contribute to the development of innovative financial valuation of building assets and financing instruments (e.g. integrating loans with differentiated interest rates) and establishing business case for deep renovation to motivate private investment.

 

BACKGROUND

The Union is committed to develop a sustainable, competitive, secure and decarbonised energy system by 2050. Member States should seek a cost-efficient equilibrium between decarbonising energy supplies and reducing final energy consumption. To reach these targets, new challenges and requirements are stated in the revised EPBD (amended 30 May 2018) which Member States shall bring into force by 10 March 2020.

 

European standards were developed under the Commission Mandate M/480 to the European Committee for Standardisation (CEN) for the assessment of the energy performance of buildings while European projects were started as support actions for common implementation and to promote skills development and education in the construction and energy efficiency sectors.

 

ALDREN METHODOLOGY

ALDREN has been conceived to catalyse the EPBD requirements through a structure composed by the following modules:

 

>T2.1_Overall Integration

A holistic procedure to assess the overall benefits from building deep renovation – regarding energy performance, confidence in the savings, high quality indoor environments, financial valuation – is needed to engage property owners and stakeholders on deep renovation pathways.

 

>T2.2_Energy Rating and Targets (EVCS)

ALDREN EVC sets the conditions for a consistent benchmark of energy performance at EU level, based on an EU comparable scale with one reference point reflecting approximately the cost optimal level of energy performance. These measures ease the labour of financial institutions and offers the possibility to be linked to existing voluntary certification schemes.

 

>T2.3_Measuring energy

ALDREN proposes the use of validated simulation models based on accurate descriptions of operations, targeting building´s energy performance. The results will be verified during operation through specific submetering systems. To deliver these goals ALDREN provides 2 key documents, a design for testability protocol and a performance verification tool.

 

>T2.4_Health and Wellbeing

ALDREN defines an IEQ rating and the integration of benefits resulting from higher IEQ in the financial valuation of the deep energy renovation projects.

 

>T2.5_Financial Valuation

Financial valuation in the ALDREN project sets a framework to establish explicitly the link between the certified energy performance, wellbeing and IEQ and financial and economic indicators.

 

>T2.6_Building Renovation Passport

Provides building information to the property owners, to the building stock managers who must deal with investment and renovation issues and to potential purchasers, investors, renters or building users.

 

>T3.2_Training

The ALDREN project will provide a certification scheme relevant content for training building professionals.

 

If Member States would adopt the ALDREN outcomes, this would not only facilitate the transposition of the revised EPBD (and save money on national level) but also be a step towards European harmonisation.
