The aim of the partnership was to confront national and regional regulation and preferences on designing, building and renovating low-energy housing (even "positive energy" houses) through concrete examples in new construction and restoration technology, with authorities.Partners in 4 countries have compared and demonstrated, in learning situations with trainees, Energy Performance Diagnosis (EPD) with value-added thanks to the use of a thermographic camera and digitally-edited process on associated pictures. Not only wanted this new pedagogical approach made learning energy-efficient-housing technologies attractive, but the trainees have also developped foreign language, multicultural skills and international team as well as test the European qualifications of the curricula in real dynamic labour market.There would also be several benefits at the European level : 1. A common pedagogical documentation on the Energy Performance Diagnosis plus IR test in housing technology was the first result in English, aiming to tend to narrow the gap between the participating countries’ adaptation of their housing construction and maintenance technology.2. A common method (operating mode) for the realization of a pedagogic Energy Performance Diagnosis plus IR test (Testing conditions, pre-requisite data, thermal camera settings, etc...) adaptable to each constructing mode, with value-added thanks to the use of a thermo graphic camera and digitally-edited process on associated pictures.3. A precise analysis of our EPD results with the maximum same input data.4. The content of a vocational training course was the second result for building-accident victims who could be reintegrated into Energetic Performance diagnosis career or for people interested in creating a business dealing with real estate technical diagnosis.
