As part of the Athens_Wave project, energy audits and techno-economic studies were conducted for the building housing the 18^th Unified High School of Athens located at 11 L. Ionias – Ros – Dairpfeld Street in the Municipality of Athens. The building was constructed in 1978 and covers a total surface area of 4.740,87 m².
