The project Consortium was established according to professional and educational experience and competences in the fields relevant to Passivhaus design, as well as to the willingness to disseminate the project results after this project ends. 

was established in 1996 as an independent research institute in Darmstadt, Germany. Having developed the concept of cost effective Passivhaus buildings, the institute has gathered many years of experience in the field of research, simulation, quality assurance, design, implementation, project support, measurement and evaluation, training and dissemination in the field of Passivhaus design as well as complete and step-by-step refurbishments with high energy performance. The PHI was the scientific leader of the European CEPHEUS Project and played a substantial role in the EU “Intelligent Energy Europe” project PEP, Passive On, Pass-Net , CEPH. The PHI develops training material and conducts training for architects, engineers and crafts. Four times per year exams are offered globally for trained candidates to become a Certified Passivhaus Designer, Certified Passivhaus Consultant or a Certified Passivhaus Tradesperson. Today there are more than 4000 Certified Passivhaus Designers around the globe. Trainers for such courses are also regularly trained by the PHI

is an independent research Institute which aims to promote the Passivhaus design and nZEB concepts throughout the Mediterranean area, with focus on Italy. ZEPHIR offers consulting, certification and training for designers and tradespeople for low-energy building standards. Within ZEPHIR there are a number of skilled researchers, among which one finds Passivhaus Certifiers, Passivhaus Trainers, Passivhaus  Designers as well as PhD and post-graduate people. ZEPHIR trained several hundreds of people in the use of PHPP tool, as well as in the topics of dynamic simulations, thermal bridges, solar shading analysis, construction of low-energy buildings. Their services also include determination and measurement of indoor air quality and the validation of climate data.

was founded in 2012 in Athens. The organization was established in a decision to join expertize of scientists from the fields of Engineering, Law and Communication in order to promote passive house principles in building sector in Greece and eastern Mediterranean. The Institute has become a leadership organization in Greece for the adoption of the Passivhaus standard and it’s methodology. Their mission is to promote energy efficiency and Passivhaus standard to the industry and government by delivering education to the building sector professionals, by offering scientific and technical support to local  projects and by cooperation with the Public Authorities, Universities, and other relevant organizations, which all recognized the Passivhaus principles as one of the solutions to the implementation of the nZEB 31/2010 EU Directive.

is the oldest civil engineering faculty in Croatia conducting university education at an undergraduate, graduate and postgraduate level in all branches of civil engineering. It is continually developing and advancing higher education, scientific research activities and overall education, and actively participates in the development of the profession and implementation of new technologies. The scientific work of the Faculty is carried out in the framework of national and international scientific projects, including projects that are dealing with research and development of new products, such as ECO-SANDWICH® wall panels.  The Faculty is partner for training in Green Project Management as well as performing Long Life Learning programme for construction engineers approved from Ministry of Construction. It performs education programme for Certified Auditors for Energy Performance of Buildings and licenced Infrared Training for thermography professionals.

The Coordinator of the project, OIKON – Institute for applied ecology, Croatia
is a multidisciplinary company dealing with environmental issues, that has successfully finished more than 500 projects, both national and international. Oikon participated in numerous R&D projects, as well as educational projects, latest being the EU ERASME Project  and have strong experience in project management. The Oikon has a goal to establish capacities within newly created Department for sustainable architecture, which will employ existing Passivhaus experts engaged in this project and train new group of experts, capable of taking advantages of synergistic use of the existing Oikon’s multidisciplinary knowledge (on natural resources, climate, modeling and energy efficiency), thus creating possibilities for future project development, creation of new ideas and new job opportunities.


Passivhaus is a building, for which thermal comfort (ISO 7730) can be achieved solely by post-heating or post-cooling of the fresh air mass, which is required to achieve sufficient indoor air quality conditions – without the need for additional recirculation of air.
