The aim of the Pythagoras project is the development and assessment of Greek national trainingmaterial in the sector of indoor environmental quality. The need for education in this specific sector isdictated by the significant indoor environment deterioration and associated health hazards, which arecaused by low ventilation levels, combined with the use of many modern building materials thataggravate pollutants emissions. Early in the project, a review is undertaken of the internationalliterature and the syllabuses of foreign research and educational institutions active in indoorenvironment quality issues. At the same time, the requirements of the Greek educational and broadersociety, related to issues of indoor pollution and health, are determined. A training methodology isconsequently developed, with the objective to optimally cover all the parameters associated with theindoor environment quality, for trainees of various disciplines. The training material is produced both inprinted (book) and integrated electronic (e-learning) format. Additionally, four seminars are organizedcovering the respective sections of the training package. The training package is being assessed bothby the trainees but also by international experts in the sector of indoor environment quality.
