Dear Ladies and Gentleman,


After five successful international conferences with the topic “High-quality retrofit” I am pleased to invite you to the “ökosan`15” conference.

“ökosan`15” will take place from 17 until 19 of June 2015 in Graz. Main focus of the conference will be on high-quality retrofit and redensification in timber construction systems.


As first event, on Wednesday 17 of June, a technical tour to high-quality retrofit projects will be undertaken.
On Thursday 18 and Friday 19 key-notes and technical presentation dealing with the topics energetic optimised retrofit and redensification of existing buildings will be given.

Besides these presentation, a poster exhibition and an exhibition of innovative companies complements the “ökosan`15” conference.
