Europe is already looking into “Affordable low energy buildings”! See more about the most recent project and the Bulgarian participation in it!

The AZEB Project


The project Affordable Zero-Energy Buildings (AZEB) collects, develops and integrates existing solutions for cost effective NZEB’s


AZEB aims to achieve significant construction and lifecycle cost reductions of new NZEB’s through integral process optimization in all construction phases. AZEB means Affordable Zero Energy Buildings. This EU project will create a common methodology for cost effective NZEB and pave the way for innovation. In the 30-month project 8 partners from Italy, Spain, Bulgaria, Germany, France and The Netherlands work together till end 2019.


Although every new building must be a nearly zero energy building according to European legislation from end 2020, the current pace of development is too low. One of the causes is that it is considered to be too expensive. Optimizing construction processes to fully integrate available solutions in the areas of process, technology and contracting is seen as the largest potential in lifecycle cost reduction. The AZEB project will pave the way for the process and organizational innovation in construction, to enable significant cost reduction and solid market acceptance of NZEB’s.


Creating a common NZEB methodology


The main steps of the AZEB project are to evaluate available experience and solutions to create a common methodology for cost reduction, apply the methodology to demonstration projects, finalise the methodology including lessons learned and disseminate the results. Training programs are made for different target groups in the construction and installation sector. These are distributed through existing and new online and offline platforms. See for more information about this ambitious project.


8 partners from 6 countries


The 8 partners are diverse: three knowledge institutes, a university, a housing corporation, a medium sized and a large contractor and an organization representing SME sustainable entrepreneurs in the construction and installation sector. They come from Italy, Spain, Bulgaria, Germany, France and The Netherlands. Due to the high diversity of context, background and competences, much is expected of the collaboration.


In Bulgaria, Oberon Konzeptbau is involved. Being the first building company which successfully realised a certified private Passive house (the Passive house standard is one of the highest world-wide recognised standards for energy efficiency) in 2015 in Bulgaria, Oberon already has significant experience in this area. Now, they goal is to further popularise and develop the energy-efficient buildings, such that hey become standard alternative to conventional projects.


Horizon 2020 program


AZEB has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement number 754174. With AZEB an amount of nearly 2 million euro is involved.
