Zielone dachy w Termach Maltańskich
Short description of the intervention
The project involves building two green roofs on saunas in Water Park ‘Termy Maltanskie’ in Poznan. The roofs serve multiple purposes including rainwater retention, thermal insulation, habitat for insects, improvement of the air quality by the production of oxygen and absorption of CO2, and aesthetic functions for the visitors to the amenities [1,2,3].

Comments and notes
Comments
There were no official documents/reports in relation to the project available. However, the company that implemented the project has a promotional video (available here: http://www.garte.pl/zielone-dachy) that takes the initiative in Termy Maltanskie as an example to discuss the potential benefits of the green roofs. Therefore the sections on the short project description and goals were based on the information from the company's website. (Updated in 2017)
