Oikostegi - Green Roof in Greece

Greece is known for its ancient culture and well-preserved historic architecture. Did you know they also have green roofs (Oikostegi in Greek)?

The most recent green roof in Greece is on the Treasury building in Athens. Used as a scientific test bed, much like the green roofs in Chicago, this green roof was shown to reduce cooling cost for the 10 story structure by 8% and heating costs by 4%. While these may not seem very significant numbers, they are only part of the equation.

Green roofs not only reduce heating and cooling costs, but also reduce storm water runoff, as well as reducing fine particulate air pollution. Additionally, photovoltaic cells perform more efficiently on green roofs, due to cooler roof temperatures.

Greece can benefit from more green roofs due to its hot summer climate, as well urban air pollution. In a land of ancient beauty, green roofs fit right in!
