Statistical Analysis of SEEDpass Survey


Knowledge on Passivhaus building design, which requires integral approach and thus encompasses knowledge of different building sector’s professions in one design process, is still very dispersive among different professions. According to survey results it is evident that respective building sector professions lack knowledge required for integral aproach to energy efficient solutions.  Without doubt, the results of the survey show that level of education, different building sector professions and currently available further education in energy efficiency is in a direct relationship with the level of knowledge on Passivhaus design.

Even though in all of the countries part of the respondents stated that they have some kind of currently available additional education in energy efficiency, overall results on Passivhaus design knowledge in Croatia and Greece deviate significantly from the ones in Italy. It is a fact that Italy has introduced Passivhaus building design education on national level 5 years ago, which could implicate that this enforced better overall knowledge results in the case of Italy.
It was expected at the beginning of the Survey, and the results of the statistical analysis have confirmed, that mechanical and electrical engineers lack the basic knowledge on architectural design, whereas architects and civil engineers lack the basic knowledge on building services, in all of the countries. Lack of knowledge, which is required to design energy efficient solutions, and needed to accomplish interior comfort conditions in a feasible manner, is detected overall in every building sector’s profession.
On the other hand, some Survey participating countries have a long record of disseminating information on Passivhaus developments throughout different nationally and internationally funded projects. Regardless that, the level of knowledge needed for designing energy efficient buildings has shown to be still not good enough. This could indicate that the pure dissemination of information cannot guarantee the channeling of the required specific knowledge itself. Going step further and directly offering specific knowledge to the professionals, aside the general information itself, as in the case of Italy, is the next logical step towards bridging the knowledge gap for countries such as Croatia and Greece.With this survey, SEEDpass has enhanced the importance of better education quality, but also the importance of availability of such education on national level.

The national development of high-tech buildings in compliance with the nZEB Directive cannot be possible to achieve only by the legislation definition that numerically describes the nZEB standard. Just as the implementation of the EPBD regulations required additional vocational training for jobs in energy certification, additional professional knowledge for the implementation of much more demanding nZEB directive is the next logical step.
Survey has confirmed that in depth Passivhaus building design educational materials, currently being developed by the SEEDpass Consortium, is without doubt beneficial step to further provision of nZEB solutions.

The criteria of the Passivhaus standard are clear and unambiguous.
