Duration: 32 months, from 1st March 2014 to 31st October 2016




RePublic_ZEB proposal is focused on the economically sustainable strategies and policies to enforce the refurbishment of the public building stock towards nZEB levels, according to EU 20/20/20 target. Thus, the main objectives of the RePublic_ZEB proposal are to support the South-Eastern European countries to promote on the market a set of concrete technical solutions for the refurbishment of the public building stock toward nZEB by increasing the involved key actors’ confidence on nZEB, and to take concrete steps to accelerate the existing public building renovations. The project mainly focuses on the Mediterranean and the South-East European countries, as there are common conditions in terms of climate, energy performance (both cooling and heating  are important) and available RES potential.

The proposal aims to achieve the objectives through the following phases:

  1. analysis of the public building stock and definition of reference buildings;
  2. assessment of the status quo and analysis of opportunities for refurbishing public buildings towards nZEB;
  3. costs/benefits analysis of the “packages of measures” for the refurbishment towards nZEB;
  4. strategies and guidelines towards nZEBs;
  5. involvement of stakeholders and authorities;
  6. communication and dissemination.

The implementation of RePublic_ZEB proposal in the context of the IEE will bring together different professionals from countries with different energy obstacles and achievements, to develop strategies for the refurbishment towards nZEB of the public building stock, according to the EU 20/20/20 target.
In order to achieve the predicted goals, the key actors involved will be: builders and public building owners, policy developers (authorities), building technology industries and national professionals associations referred to the building industry as architects and engineers. The project primary target group and beneficent will be the relevant Government authorities (from the proposal member’s countries) responsible for the legislation in the area of energy and buildings, as nZEB concept, as well as EPBD recast costs/benefits analysis requirements, are not fully implemented within national regulations yet. In order to promote a large-scale agreements and commitments amongst market actors, and facilitate the building and building technology markets renovations, the secondary target group cover: varieties of Energy Service Companies (ESCOs) and other energy efficiency service providers; energy professionals and energy agencies; national and local authorities (building owners); builders, producers, distributors, installers, and the associations of these, engaged with building renovation materials and measures, both in the field of energy efficiency and renewable energy and stakeholders.
