13th International BUILDAIR Symposium, 2-3 June 2023, Hannover, Germany

This presentation is the recording of the first 100 airtight tests in Greece, from 2010 until today. The inspections were carried out in private homes and in large-scale commercial buildings, of different construction dates, renovated or not, in various cities of the country and on islands. Most of the inspections were carried out in the area of Attica and in the city of Athens. From the above recording, very useful conclusions emerge about how energy sustainable the cities that have been built in the last 60 years are, their energy footprint and above all the habits of the population that lives in them. Wasteful buildings have created wasteful people and habits with the result that there is a risk of failure of energy upgrade moves, energy savings and a substantial reduction of the energy footprint. The construction techniques used in the past have evolved little, resulting in the use of state-of-the-art materials with old techniques. This results in the failure of new materials and often has more negative consequences than the problems they are trying to solve. A specific method was followed to record the results and the final conclusions described at the end. In addition to recording the inspections, building users, engineers and craftsmen were interviewed on the subject of the airtight housing.
